    DOSAGE & INDICATIONS

    For asthma maintenance treatment.
    Oral Inhalation dosage (inhalation aerosol; i.e., Qvar Redihaler)
    Adults

    40 to 80 mcg (1 to 2 oral inhalations of 40 mcg/actuation) twice daily, approximately 12 hours apart for patients not currently on an inhalational corticosteroid (ICS). For patients switching from another ICS, select the initial dose based on previous product use and disease severity (40 to 320 mcg twice daily). May titrate after 2 weeks of initial therapy if response is not adequate. Max: 4 oral inhalations of the 80 mcg/actuation twice daily (320 mcg twice daily). Improvement in asthma symptoms can occur within 24 hours of the beginning of treatment and should be expected within the first or second week, but maximum benefit should not be expected until 3 to 4 weeks of therapy. Improvement in pulmonary function is usually apparent within 1 to 4 weeks after the start of therapy. Titrate to the lowest effective dose once asthma stability is achieved.

    Children and Adolescents 12 years and older

    40 to 80 mcg (1 to 2 oral inhalations of 40 mcg/actuation) twice daily, approximately 12 hours apart for patients not currently on an inhalational corticosteroid (ICS). For patients switching from another ICS, select the starting dosage based on the previous product use and disease severity (40 to 320 mcg twice daily). May titrate after 2 weeks of initial therapy if response is not adequate. Max: 4 oral inhalations of the 80 mcg/actuation twice daily (320 mcg twice daily). Improvement in asthma symptoms can occur within 24 hours of the beginning of treatment and should be expected within the first or second week, but maximum benefit should not be expected until 3 to 4 weeks of therapy. Improvement in pulmonary function is usually apparent within 1 to 4 weeks after the start of therapy. Titrate to the lowest effective dose once asthma stability is achieved.

    Children 4 to 11 years

    40 mcg (1 oral inhalation of 40 mcg/actuation) twice daily, approximately 12 hours apart, is the recommended starting dosage. Base starting dosage on previous asthma therapy and asthma severity. May titrate to 80 mcg (2 oral inhalations of 40 mcg/actuation or 1 oral inhalation of 80 mcg/actuation) twice daily after 2 weeks if response is not adequate. Max: 2 oral inhalations of 40 mcg/actuation or 1 oral inhalation of 80 mcg/actuation twice daily (80 mcg twice daily). Improvement in asthma symptoms can occur within 24 hours of the beginning of treatment and should be expected within the first or second week, but maximum benefit should not be expected until 3 to 4 weeks of therapy. Improvement in pulmonary function is usually apparent within 1 to 4 weeks after the start of therapy. Titrate to the lowest effective dose once asthma stability is achieved.

For other patients, select dose based on previous therapy and asthma severity (40 to 320 mcg twice daily). Max: 4 oral inhalations of the 80 mcg/actuation twice daily (320 mcg twice daily). Titrate to the lowest effective dose. Regular ICS (controller) use reduces the incidence of EIB.

    Children and Adolescents 12 years and older

    40 to 80 mcg (1 to 2 oral inhalations of 40 mcg/actuation) twice daily, approximately 12 hours apart is the recommended dosing for asthma maintenance in patients not currently on an inhalational corticosteroid. For other patients, select dose based on previous therapy and asthma severity (40 to 320 mcg twice daily). Max: 4 oral inhalations of the 80 mcg/actuation twice daily (320 mcg twice daily). Efficacy for EIB has been studied in pediatric patients. Titrate to the lowest effective dose. Regular ICS (controller) use reduces the incidence of EIB.

    Children 6 to 11 years

    40 mcg to 80 mcg (1 to 2 oral inhalations of the 40 mcg/actuation or 1 oral inhalation of the 80 mcg/actuation) twice daily, approximately 12 hours apart, is the recommended dosing. Max: 1 oral inhalation of the 80 mcg/actuation twice daily (80 mcg twice daily). Efficacy for EIB has been studied in pediatric patients. Titrate to the lowest effective dose. Regular ICS (controller) use reduces the incidence of EIB.

    Children 5 years

    40 to 80 mcg (1 to 2 oral inhalations of the 40 mcg/actuation or 1 oral inhalation of the 80 mcg/actuation) twice daily, approximately 12 hours apart, is the recommended dosing. Max: 1 oral inhalation of the 80 mcg/actuation twice daily (80 mcg twice daily). Efficacy for EIB has been studied in pediatric patients, using as low as once-daily dosing. Titrate to the lowest effective dose. Regular ICS (controller) use reduces the incidence of EIB.

    For the maintenance treatment of chronic obstructive pulmonary disease (COPD)† (e.g., chronic bronchitis† and emphysema†).
    Oral Inhalation dosage (inhalation aerosol; i.e., Qvar Redihaler)
    Adults

    The optimal dose for COPD is not established, although inhaled corticosteroids (ICS) are well-accepted treatments for patients at risk for exacerbation per COPD guidelines. Typical doses range from 40 to 320 mcg inhaled orally twice daily, using commercially available products. Max: 4 actuations of 80 mcg/actuation twice daily (320 mcg twice daily).  High dose therapy (up to 1,000 mcg inhaled twice daily) has also been studied, using formulations not commercially available. Do not use for the relief of acute bronchospasm; use a short-acting beta-2 agonist (SABA). According to the Global Initiative for Chronic Lung Disease (GOLD) guidelines, ICS may be used in combination with an inhaled long-acting beta-2 agonist (LABA) as initial therapy in group D (those with a high risk of exacerbation). Combination of a LABA with an ICS has the greatest likelihood of reducing exacerbations in patients with blood eosinophil counts of 200 cells/microL or more. An ICS combined with a LABA is more effective than the individual components in improving lung function and health status and reducing exacerbations in patients with exacerbations and moderate to very severe COPD; however clinical trials failed to demonstrate a statistically significant effect on survival. At follow-up, if the patient is still experiencing dyspnea, consider switching inhaler device and investigate for other causes of dyspnea. If the patient has exacerbations, consider triple therapy with a long-acting muscarinic antagonist (LAMA), a LABA, and an inhaled corticosteroid (ICS).

    ADMINISTRATION

    Inhalation Administration
    Oral Inhalation Administration

    General Information
    To avoid the spread of infection, do not use the inhaler for more than one person.
    Instruct patient on proper use of the inhaler device; see manufacturer's "Instructions for Use".
     
    Oral inhalation (HFA pressurized, metered-dose aerosol) (Qvar Redihaler):
    The canister does not require shaking prior to administration; do not shake the inhaler with the cap open to avoid possible actuation of the device.
    The white cap on the Redihaler must be closed before each inhalation; do not open the white cap until ready to give the inhalation. If the dose requires more than 1 inhalation the white cap must be closed between each inhalation.
    Do not use with a spacer device or volume holding chamber with the Redihaler.
    The Redihaler does not require priming.
    The Redihaler has a dose counter attached to the actuator. When first opened, the number 120 will be displayed. The dose counter will count down each time a spray is released. When the dose counter reaches 20, red numbers appear warning to refill the medication.
    Instruct patient on proper inhalation technique for the device.
    After administration, have patient rinse mouth thoroughly with water without swallowing to remove beclomethasone deposited in the mouth.
    Keep the inhaler clean and dry. For normal hygiene, clean the mouthpiece of the inhaler with a clean dry tissue or cloth. Do not put any part of the Redihaler in water; if washed or placed in water the inhaler must be replaced. Never take the Redihaler apart.
    Throw away the Redihaler when the dose counter displays 0 (background will be a solid red) or the product expires, whichever comes first. Do not throw away in a fire or incinerator.
    Storage: Keep the white cap on the inhaler closed during storage. Store so the inhaler rests on the concave end of the canister with the plastic actuator on top when not being used. Store at room temperature. Do not use or store near heat or open flame. Exposure to temperatures above 120 degrees F (49 degrees C) may cause the canister to burst.

    Intranasal Inhalation Administration

    Different nasal dosage forms are commercially available. Products are not always interchangeable due to differences in route of administration and in the amount of active drug released per spray.
    To avoid the spread of infection, do not use the container for more than 1 person.
     
    Nasal inhalation (metered-dose aerosol) (i.e., Qnasl):
    Instruct patient to shake the canister well before administering.
    Prior to first use, instruct the patient to prime the pump by actuating 4 times into the air, away from the eyes and face. After the initial priming, the dose-counter should read 120 (120-actuation products) or 60 (60-actuation products).
    If the canister is not used for 7 consecutive days, instruct the patient to prime by actuating 2 times.
    Instruct patient on proper administration technique (see manufacturer-provided patient instructions).
    After administration, wipe the nasal actuator tip with a clean, dry tissue or cloth. Replace the cap right after cleaning.
     
    Nasal inhalation (pump spray) (e.g., Beconase AQ):
    Instruct patient to shake the nasal sprayer well before administering.
    Prior to first use, instruct the patient to prime the pump by actuating 6 times into the air or until a fine spray appears, away from the eyes and face.
    If the pump is not used for 7 consecutive days, instruct the patient to prime by actuating until a fine spray appears.
    Instruct patient on proper administration technique (see manufacturer-provided patient instructions).
    After administration, rinse the tip of the bottle with hot water, taking care not to suck water into the bottle, and dry with a clean tissue. Replace the cap right after cleaning.

    CONTRAINDICATIONS / PRECAUTIONS

    General Information

    Use of beclomethasone does not contraindicate administration of live-virus vaccines. According to the Advisory Committee on Immunization Practices (ACIP), administration of live-virus vaccines is safe and effective when steroid therapy is administered by the inhalation route.

    Acute bronchospasm, status asthmaticus

    Inhaled beclomethasone is contraindicated as primary therapy for patients with status asthmaticus or other types of acute episodes of asthma, such as acute bronchospasm, for which intensive and immediate therapy is warranted. Patients should be advised that beclomethasone is not to be used as a bronchodilator and is not indicated for relief of acute bronchospasm. Although inhaled corticosteroids (ICSs) are not indicated for primary treatment of an acute exacerbation, they may be initiated at any time during an exacerbation for patients not using long-term control therapy. An ICS may also be continued during an exacerbation for patients previously using the drug for chronic control. Additionally, the drug is contraindicated for use in any patient with a known hypersensitivity to beclomethasone.

    Paradoxical bronchospasm

    As with other inhaled asthma medications, paradoxical bronchospasm can occur with an immediate increase in wheezing after administration of inhaled beclomethasone that may be life-threatening. If bronchospasm occurs after dosing, treat the patient immediately with a fast-acting inhaled bronchodilator, discontinue beclomethasone, and institute alternative therapy.

    Abrupt discontinuation, adrenal insufficiency, Cushing's syndrome, hypothalamic-pituitary-adrenal (HPA) suppression, surgery

    Systemic absorption of inhaled or intranasal beclomethasone may result in varying complications depending on the clinical situation and type of administration. Carefully observe patients for evidence of systemic corticosteroid effects and adrenal insufficiency, particularly during periods of physiologic stress (e.g., trauma, surgery, infection). Systemic absorption of inhaled or intranasal corticosteroids has produced reversible hypothalamic-pituitary-adrenal (HPA) suppression, manifestations of Cushing's syndrome, hyperglycemia, and glucosuria in some patients; use with caution in patient's with underlying Cushing's syndrome. To minimize the risk of HPA dysfunction, do not exceed recommended dosages and titrate patients to the lowest effective dosage. Patients with low body mass index (BMI) may have an increased risk of HPA suppression; some experts recommend adrenal screening in this population. If signs of HPA suppression occur, the drug should be slowly reduced; intranasal corticosteroids should be ultimately discontinued. If HPA suppression occurs with any beclomethasone formulation, patients will require systemic corticosteroids during periods of physiologic stress. If surgery is required, patients should notify all health care providers that they have received corticosteroids within the last 12 months. Use beclomethasone with caution when substituting it for systemic corticosteroid administration and avoid abrupt discontinuation; deaths due to adrenal insufficiency have been reported in asthma patients during and after such a change. Beclomethasone may not produce systemic concentrations high enough to avoid adrenocortical insufficiency in patients transitioning from systemic corticosteroids. Adult patients who have been maintained on at least 20 mg of prednisone equivalent may be most susceptible; the precise dosage that increases risk in children is not as clearly defined. Recommended doses of inhaled corticosteroids (ICSs) provide less than normal physiologic amounts of systemic glucocorticoid and do not provide the mineralocorticoid necessary for coping with stress. Patients receiving ICS may require initiation or resumption of systemic corticosteroids during periods of stress or during severe asthma attacks. When transferring patients to ICS therapy, systemic corticosteroids should be weaned slowly. Monitor patients closely for asthma control (e.g., lung function, beta-agonist use, asthma symptoms) as well as signs and symptoms of adrenal insufficiency (e.g., fatigue, lassitude, weakness, nausea, vomiting, and hypotension). Infrequently, signs and symptoms of corticosteroid withdrawal may occur, requiring supplemental systemic corticosteroids.

    Fungal infection, herpes infection, infection, measles, tuberculosis, varicella, viral infection

    The incidence or course of acute viral infection or bacterial infection is probably minimally affected by inhaled corticosteroids in most immunocompetent individuals. However, the use of inhaled beclomethasone in the presence of infection, specifically active or latent tuberculosis of the respiratory tract; untreated systemic fungal, bacterial, parasitic, or viral infections; or ocular herpes infection should be initiated or continued cautiously, if at all. Because of the potential for worsening infection, beclomethasone therapy may need to be interrupted during some active infections. Chickenpox (varicella) and measles can have a more serious or even fatal course in susceptible children using corticosteroids; the exact risk associated with inhaled beclomethasone is unclear. If an unimmunized patient is exposed to chickenpox or measles, proper prophylaxis may be indicated. Corticosteroid therapy can reactivate tuberculosis and should not be used except when chemoprophylaxis is instituted concomitantly. The use of nasal or orally inhaled beclomethasone may result in localized fungal infection of the nose, mouth, and pharynx with Candida albicans. Instruct patients to rinse mouth after each use of orally inhaled beclomethasone to minimize risk. If oropharyngeal candidiasis develops, it should be treated with appropriate local or systemic antifungal therapy while still continuing beclomethasone therapy; temporary interruption of inhaler use should only be done under close medical supervision. Patients using beclomethasone nasal spray for extended periods (i.e., months) should be examined periodically for evidence of infection or other adverse effects on the nasal mucosa.

    Malnutrition, osteoporosis, tobacco smoking

    Detrimental effects on bone metabolism, such as osteoporosis, are expected to be much lower with inhaled corticosteroids than systemically-administered corticosteroids. However, some data suggest that high-dose inhaled beclomethasone (more than 1000 mcg/day) may also decrease bone formation and increased resorption, and decreases in bone mineral density have been reported in patients receiving long-term therapy of inhaled corticosteroids. Compounding risk factors for bone loss include preexisting osteopenia, prolonged immobilization, family history of osteoporosis, tobacco smoking, malnutrition, and use of other medications that may reduce bone mass.

    Nasal septal perforation, nasal surgery, nasal trauma

    Nasal septal perforation and ulceration have been reported with intranasal beclomethasone use. As with any long-term topical treatment of the nasal cavity, patients using intranasal beclomethasone over several months or longer should be examined periodically for possible changes in the nasal mucosa. Furthermore, because of the inhibitory effect of corticosteroids on wound healing, patients who have experienced recent nasal septal perforation or ulcer, nasal surgery, or nasal trauma should not use a nasal corticosteroid until healing has occurred.

    Infants, neonates, pregnancy

    There are no adequate and well-controlled studies with beclomethasone in pregnant women; there are clinical considerations with the use of beclomethasone in pregnant women. Current studies of beclomethasone therapy during pregnancy are incomplete; but published medical literature describing the drug's use during gestation does exist. Despite adverse effects observed with the parenteral use of beclomethasone in animal studies, fetal harm from inhaled administration in humans appears remote. Human reports evaluating the use of inhaled beclomethasone currently do not support an association between drug use and congenital defects. Infants and neonates born of mothers receiving substantial doses of beclomethasone during pregnancy should, however, be observed for adrenal suppression. A position statement by the American College of Allergy, Asthma and Immunology notes that beclomethasone is a potential alternative for pregnant women requiring inhaled steroids for effective asthma or allergy management. Low-dose inhaled corticosteroids are considered first line therapy for control of mild persistent asthma during pregnancy according to the 2004 guidelines of the National Asthma Education and Prevention Program (NAEPP) Asthma and Pregnancy Working Group. Data on the use of medium to high dose inhaled corticosteroid during pregnancy are limited. However, dose titration may be considered for those with moderate to severe persistent asthma, preferably using budesonide. Due to the availability of safety information during pregnancy, budesonide is preferred over other inhaled corticosteroid. However, there are no data to indicate safety concerns with other inhaled corticosteroids, and maintaining a previously established treatment regimen may be more beneficial to the patient. Selection of any pharmacologic treatment for asthma control during pregnancy should include the specific needs of the patient, based on an individual evaluation, and consideration of the potential benefits or risks to the fetus.

    Breast-feeding

    Corticosteroids distribute into breast-milk in low concentrations; according to FDA-approved product labels of beclomethasone, caution should be exercised when administering beclomethasone to women who are breast-feeding. Beclomethasone via inhaled administration typically results in low systemic concentrations; therefore, the amount excreted into breast-milk after inhalation is expected to be very low. Reviewers and an expert panel consider inhaled and oral corticosteroids acceptable to use during breast-feeding. Low-dose inhaled corticosteroids are considered first line therapy for control of mild persistent asthma during pregnancy and lactation according to the National Asthma Education and Prevention Program (NAEPP) Asthma and Pregnancy Working Group. Due to greater availability of data in pregnancy, budesonide is the preferred agent in this population. However, there are no data to indicate safety concerns with other inhaled corticosteroids and maintaining a previously established treatment regimen may be more beneficial to the patient. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally administered drug, healthcare providers are encouraged to report the adverse effect to the FDA.

    Children, growth inhibition, increased intracranial pressure

    The safety and efficacy of nasally- and orally-inhaled formulations of beclomethasone in children varies depending on the product. A reduction in growth velocity in children may occur as a result of inadequate control of chronic diseases (e.g., asthma) or from use of corticosteroids for asthma or allergy treatment. Growth inhibition has been observed in the absence of laboratory evidence of hypothalamic-pituitary-adrenal (HPA) suppression, suggesting that growth velocity is a more sensitive indicator of systemic corticosteroid exposure in pediatric patients. The long-term effects of this reduction in growth velocity, including the impact on final adult height, are unknown. In a 56 week study of asthmatic children 6 to 8 years of age receiving montelukast 5 mg per day, inhaled beclomethasone 168 mcg twice daily, or placebo, children receiving either montelukast or placebo had higher growth rates than those receiving inhaled beclomethasone. Health care professionals should closely follow the growth of children taking beclomethasone and weigh the benefits of therapy and disease control against the possibility of growth suppression and HPA-suppression. Pediatric patients receiving maximal dosages of beclomethasone oral or intranasal inhalation may be more susceptible to these effects. To minimize the effects of intranasal or orally inhaled corticosteroids, each patient should be titrated to the lowest effective dose. Pediatric patients may be more susceptible to developing systemic toxicity; adrenal suppression and increased intracranial pressure have been reported with the use and/or withdrawal of intranasal and orally inhaled corticosteroid formulations in young patients.

    Diabetes mellitus, hyperglycemia

    Systemic absorption of inhaled corticosteroids has produced reversible hyperglycemia and glucosuria in some patients. Inhaled corticosteroids should generally be used with caution in those patients with diabetes mellitus. Exacerbation of diabetes may occur with significant systemic absorption of the inhaled corticosteroid.

    Cataracts, glaucoma, increased intraocular pressure, ocular exposure, visual disturbance

    Rare instances of glaucoma, increased intraocular pressure, and cataracts have been reported after the inhaled administration of corticosteroids. Use inhaled beclomethasone with caution in patients potentially predisposed to these conditions; have patients using beclomethasone report any unexplained visual disturbance promptly. To avoid adverse ophthalmic effects related to drug administration, remind patients to avoid unintended ocular exposure by actuating the medication properly. Patients with a change in vision or a history of increased intraocular pressure, glaucoma, or cataracts should be closely monitored during corticosteroid therapy. Consider referral to an ophthalmologist in patients who develop ocular symptoms or who use beclomethasone long term.[46707] [46709] [62224]

    Corticosteroid hypersensitivity

    Although true corticosteroid hypersensitivity is rare, patients who have demonstrated a prior hypersensitivity reaction to beclomethasone should not receive any form of beclomethasone. It is possible, though also rare, that such patients will display cross-hypersensitivity to other corticosteroids. It is advisable that patients who have a hypersensitivity reaction to any corticosteroid undergo skin testing, which, although not a conclusive predictor, may help to determine if hypersensitivity to another corticosteroid exists. Such patients should be carefully monitored during and following the administration of any corticosteroid.

    Depression, psychosis, suicidal ideation

    Use beclomethasone with caution in patients with psychosis. During postmarketing experience, psychiatric events and behavioral changes such as aggression, depression, sleep disorders, psychomotor hyperactivity, and suicidal ideation have been reported; these effects were primarily reported in children.

    Hepatic disease

    Use inhaled and intranasal beclomethasone cautiously in patients with severe hepatic disease as the drug is primarily eliminated by the liver. Adverse effects may be more pronounced in this population.

    Geriatric

    The federal Omnibus Budget Reconciliation Act (OBRA) regulates medication use in residents (e.g., geriatric adults) of long-term care facilities (LTCFs). The OBRA guidelines caution that orally inhaled corticosteroids, such as beclomethasone, can cause throat irritation and oral candidiasis, particularly if the mouth is not rinsed after administration.

    DRUG INTERACTIONS

    Abatacept: (Moderate) Concomitant use of immunosuppressives, as well as long-term corticosteroids, may potentially increase the risk of serious infection in abatacept treated patients. Advise patients taking abatacept to seek immediate medical advice if they develop signs and symptoms suggestive of infection.
    Acetaminophen; Aspirin, ASA; Caffeine: (Moderate) Salicylates or NSAIDs should be used cautiously in patients receiving corticosteroids. While there is controversy regarding the ulcerogenic potential of corticosteroids alone, concomitant administration of corticosteroids with aspirin may increase the GI toxicity of aspirin and other non-acetylated salicylates. Withdrawal of corticosteroids can result in increased plasma concentrations of salicylate and possible toxicity. Concomitant use of corticosteroids may increase the risk of adverse GI events due to NSAIDs. Although some patients may need to be given corticosteroids and NSAIDs concomitantly, which can be done successfully for short periods of time without sequelae, prolonged coadministration should be avoided.

Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Indapamide: (Moderate) Additive hypokalemia may occur when indapamide is coadministered with other drugs with a significant risk of hypokalemia such as systemic corticosteroids. Coadminister with caution and careful monitoring.
    Inebilizumab: (Moderate) Concomitant usage of inebilizumab with immunosuppressant drugs, including systemic corticosteroids, may increase the risk of infection. Consider the risk of additive immune system effects when coadministering therapies that cause immunosuppression with inebilizumab.
    Insulin Degludec; Liraglutide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment.

    Insulins: (Moderate) Monitor patients receiving insulin closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Interferon Alfa-2a: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
    Interferon Alfa-2b: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
    Interferon Alfa-2b; Ribavirin: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
    Irbesartan; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Isoproterenol: (Moderate) The risk of cardiac toxicity with isoproterenol in asthma patients appears to be increased with the coadministration of corticosteroids. Intravenous infusions of isoproterenol in refractory asthmatic children at rates of 0.05 to 2.7 mcg/kg/min have caused clinical deterioration, myocardial infarction (necrosis), congestive heart failure and death.
    Isotretinoin: (Minor) Both isotretinoin and corticosteroids can cause osteoporosis during chronic use. Patients receiving systemic corticosteroids should receive isotretinoin therapy with caution.
    Labetalol: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    L-Asparaginase Escherichia coli: (Moderate) Concomitant use of L-asparaginase with corticosteroids can result in additive hyperglycemia. L-Asparaginase transiently inhibits insulin production contributing to hyperglycemia seen during concurrent corticosteroid therapy. Insulin therapy may be required in some cases. Administration of L-asparaginase after rather than before corticosteroids reportedly has produced fewer hypersensitivity reactions.
    Levetiracetam: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    Levomethadyl: (Major) Caution is advised when using levomethadyl in combination with other agents, such as corticosteroids, that may lead to electrolyte abnormalities, especially hypokalemia or hypomagnesemia.
    Linagliptin; Metformin: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Liraglutide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued.

The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Lisinopril; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Lixisenatide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents.

Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Lomustine, CCNU: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
    Lonapegsomatropin: (Moderate) Corticosteroids can retard bone growth and therefore, can inhibit the growth-promoting effects of somatropin. If corticosteroid therapy is required, the corticosteroid dose should be carefully adjusted.
    Loop diuretics: (Moderate) Corticosteroids may accentuate the electrolyte loss associated with diuretic therapy resulting in hypokalemia and/or hypomagnesemia. While glucocorticoids with mineralocorticoid activity (e.g., cortisone, hydrocortisone) can cause sodium and fluid retention. Close monitoring of electrolytes should occur in patients receiving these drugs concomitantly.
    Losartan; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Macimorelin: (Major) Avoid use of macimorelin with drugs that directly affect pituitary growth hormone secretion, such as corticosteroids. Healthcare providers are advised to discontinue corticosteroid therapy and observe a sufficient washout period before administering macimorelin. Use of these medications together may impact the accuracy of the macimorelin growth hormone test.
    Magnesium Salicylate: (Moderate) Salicylates or NSAIDs should be used cautiously in patients receiving corticosteroids. While there is controversy regarding the ulcerogenic potential of corticosteroids alone, concomitant administration of corticosteroids with aspirin may increase the GI toxicity of aspirin and other non-acetylated salicylates. Withdrawal of corticosteroids can result in increased plasma concentrations of salicylate and possible toxicity. Concomitant use of corticosteroids may increase the risk of adverse GI events due to NSAIDs. Although some patients may need to be given corticosteroids and NSAIDs concomitantly, which can be done successfully for short periods of time without sequelae, prolonged coadministration should be avoided.
    Mannitol: (Moderate) Corticosteroids may accentuate the electrolyte loss associated with diuretic therapy resulting in hypokalemia. Also, corticotropin may cause calcium loss and sodium and fluid retention. Mannitol itself can cause hypernatremia. Close monitoring of electrolytes should occur in patients receiving these drugs concomitantly.
    Mecasermin rinfabate: (Moderate) Additional monitoring may be required when coadministering systemic or inhaled corticosteroids and mecasermin, recombinant, rh-IGF-1. In animal studies, corticosteroids impair the growth-stimulating effects of growth hormone (GH) through interference with the physiological stimulation of epiphyseal chondrocyte proliferation exerted by GH and IGF-1. Dexamethasone administration on long bone tissue in vitro resulted in a decrease of local synthesis of IGF-1. Similar counteractive effects are expected in humans. If systemic or inhaled glucocorticoid therapy is required, the steroid dose should be carefully adjusted and growth rate monitored.
    Mecasermin, Recombinant, rh-IGF-1: (Moderate) Additional monitoring may be required when coadministering systemic or inhaled corticosteroids and mecasermin, recombinant, rh-IGF-1. In animal studies, corticosteroids impair the growth-stimulating effects of growth hormone (GH) through interference with the physiological stimulation of epiphyseal chondrocyte proliferation exerted by GH and IGF-1. Dexamethasone administration on long bone tissue in vitro resulted in a decrease of local synthesis of IGF-1. Similar counteractive effects are expected in humans. If systemic or inhaled glucocorticoid therapy is required, the steroid dose should be carefully adjusted and growth rate monitored.
    Meglitinides: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Mepenzolate: (Minor) Anticholinergics, such as mepenzolate, antagonize the effects of antiglaucoma agents. Mepenzolate is contraindicated in patients with glaucoma and therefore should not be coadministered with medications being prescribed for the treatment of glaucoma. In addition, anticholinergic drugs taken concurrently with corticosteroids in the presence of increased intraocular pressure may be hazardous.
    Metformin: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Metformin; Repaglinide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells. (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued.

The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Metformin; Sitagliptin: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Methazolamide: (Moderate) Corticosteroids may increase the risk of hypokalemia if used concurrently with methazolamide. Hypokalemia may be especially severe with prolonged use of corticotropin, ACTH. Monitor serum potassium levels to determine the need for potassium supplementation and/or alteration in drug therapy. The chronic use of corticosteroids may augment calcium excretion with methazolamide leading to increased risk for hypocalcemia and/or osteoporosis.
    Methenamine; Sodium Acid Phosphate: (Moderate) Use sodium phosphate cautiously with corticosteroids, especially mineralocorticoids or corticotropin, ACTH, as concurrent use can cause hypernatremia.
    Methenamine; Sodium Acid Phosphate; Methylene Blue; Hyoscyamine: (Moderate) Use sodium phosphate cautiously with corticosteroids, especially mineralocorticoids or corticotropin, ACTH, as concurrent use can cause hypernatremia.
    Methoxsalen: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
    Methyclothiazide: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Metolazone: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Metoprolol; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Metyrapone: (Major) Medications which affect pituitary or adrenocortical function, including all corticosteroid therapy, should be discontinued prior to and during testing with metyrapone. Patients taking inadvertent doses of corticosteroids on the test day may exhibit abnormally high basal plasma cortisol levels and a decreased response to the test. Although systemic absorption of topical corticosteroids is minimal, temporary discontinuation of these products should be considered if possible to reduce the potential for interference with the test results.
    Micafungin: (Moderate) Leukopenia, neutropenia, anemia, and thrombocytopenia have been associated with micafungin. Patients who are taking immunosuppressives such as the corticosteroids with micafungin concomitantly may have additive risks for infection or other side effects. In a pharmacokinetic trial, micafungin had no effect on the pharmacokinetics of prednisolone. Acute intravascular hemolysis and hemoglobinuria was seen in a healthy volunteer during infusion of micafungin (200 mg) and oral prednisolone (20 mg). This reaction was transient, and the subject did not develop significant anemia.
    Midazolam: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    Mifepristone: (Major) Mifepristone for termination of pregnancy is contraindicated in patients on long-term corticosteroid therapy and mifepristone for Cushing's disease or other chronic conditions is contraindicated in patients who require concomitant treatment with systemic corticosteroids for life-saving purposes, such as serious medical conditions or illnesses (e.g., immunosuppression after organ transplantation). For other situations where corticosteroids are used for treating non-life threatening conditions, mifepristone may lead to reduced corticosteroid efficacy and exacerbation or deterioration of such conditions. This is because mifepristone exhibits antiglucocorticoid activity that may antagonize corticosteroid therapy and the stabilization of the underlying corticosteroid-treated illness. Mifepristone may also cause adrenal insufficiency, so patients receiving corticosteroids for non life-threatening illness require close monitoring. Because serum cortisol levels remain elevated and may even increase during treatment with mifepristone, serum cortisol levels do not provide an accurate assessment of hypoadrenalism. Patients should be closely monitored for signs and symptoms of adrenal insufficiency, If adrenal insufficiency occurs, stop mifepristone treatment and administer systemic glucocorticoids without delay; high doses may be needed to treat these events. Factors considered in deciding on the duration of glucocorticoid treatment should include the long half-life of mifepristone (85 hours).
    Mitoxantrone: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
    Mivacurium: (Moderate) Limit the period of use of neuromuscular blockers and corticosteroids and only use when the specific advantages of the drugs outweigh the risks for acute myopathy. An acute myopathy has been observed with the use of high doses of corticosteroids in patients receiving concomitant long-term therapy with neuromuscular blockers. Clinical improvement or recovery after stopping therapy may require weeks to years.
    Moxifloxacin: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    Natalizumab: (Major) Ordinarily, patients receiving chronic immunosuppressant therapy should not be treated with natalizumab. Treatment recommendations for combined corticosteroid therapy are dependent on the underlying indication for natalizumab therapy. Corticosteroids should be tapered in those patients with Crohn's disease who are on chronic corticosteroids when they start natalizumab therapy, as soon as a therapeutic benefit has occurred. If the patient cannot discontinue systemic corticosteroids within 6 months, discontinue natalizumab. The concomitant use of natalizumab and corticosteroids may further increase the risk of serious infections, including progressive multifocal leukoencephalopathy, over the risk observed with use of natalizumab alone. In multiple sclerosis (MS) clinical trials, an increase in infections was seen in patients concurrently receiving short courses of corticosteroids. However, the increase in infections in natalizumab-treated patients who received steroids was similar to the increase in placebo-treated patients who received steroids. Short courses of steroid use during natalizumab, such as when they are needed for MS relapse treatment, appear to be acceptable for use concurrently.
    Nateglinide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Nelarabine: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
    Neostigmine: (Moderate) Concomitant use of anticholinesterase agents, such as neostigmine, and systemic corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, anticholinesterase agents should be withdrawn at least 24 hours before initiating systemic corticosteroid therapy.
    Neuromuscular blockers: (Moderate) Limit the period of use of neuromuscular blockers and corticosteroids and only use when the specific advantages of the drugs outweigh the risks for acute myopathy. An acute myopathy has been observed with the use of high doses of corticosteroids in patients receiving concomitant long-term therapy with neuromuscular blockers. Clinical improvement or recovery after stopping therapy may require weeks to years.
    Nicardipine: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    Nonsteroidal antiinflammatory drugs: (Moderate) Although some patients may need to be given corticosteroids and NSAIDs concomitantly, which can be done successfully for short periods of time without sequelae, prolonged concomitant administration should be avoided. Concomitant use of corticosteroids appears to increase the risk of adverse GI events due to NSAIDs. Corticosteroids can have profound effects on sodium-potassium balance; NSAIDs also can affect sodium and fluid balance. Monitor serum potassium concentrations; potassium supplementation may be necessary. In addition, NSAIDs may mask fever, pain, swelling and other signs and symptoms of an infection; use NSAIDs with caution in patients receiving immunosuppressant dosages of corticosteroids. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
    Ofatumumab: (Moderate) Concomitant use of ofatumumab with corticosteroids may increase the risk of immunosuppression. Monitor patients carefully for signs and symptoms of infection. Ofatumumab has not been studied in combination with other immunosuppressive or immune modulating therapies used for the treatment of multiple sclerosis, including immunosuppressant doses of corticosteroids.
    Olmesartan; Amlodipine; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids.

    Olmesartan; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Ondansetron: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    Oxymetholone: (Moderate) Concomitant use of oxymetholone with corticosteroids or corticotropin, ACTH may cause increased edema. Manage edema with diuretic and/or digitalis therapy.
    Pancuronium: (Moderate) Limit the period of use of neuromuscular blockers and corticosteroids and only use when the specific advantages of the drugs outweigh the risks for acute myopathy. An acute myopathy has been observed with the use of high doses of corticosteroids in patients receiving concomitant long-term therapy with neuromuscular blockers. Clinical improvement or recovery after stopping therapy may require weeks to years.
    Pegaspargase: (Moderate) Monitor for an increase in glucocorticoid-related adverse reactions such as hyperglycemia and osteonecrosis during concomitant use of pegaspargase and glucocorticoids.
    Penicillamine: (Major) Agents such as immunosuppressives have adverse reactions similar to those of penicillamine. Concomitant use of penicillamine with these agents is contraindicated because of the increased risk of developing severe hematologic and renal toxicity.
    Phenylephrine: (Moderate) The therapeutic effect of phenylephrine may be increased in patient receiving corticosteroids, such as hydrocortisone. Monitor patients for increased pressor effect if these agents are administered concomitantly.
    Photosensitizing agents (topical): (Minor) Corticosteroids administered prior to or concomitantly with photosensitizing agents used in photodynamic therapy may decrease the efficacy of the treatment.
    Physostigmine: (Moderate) Concomitant use of anticholinesterase agents. such as physostigmine, and systemic corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, withdraw anticholinesterase inhibitors at least 24 hours before initiating corticosteroid therapy.
    Pimozide: (Moderate) According to the manufacturer of pimozide, the drug should not be coadministered with drugs known to cause electrolyte imbalances, such as high-dose, systemic corticosteroid therapy. Pimozide is associated with a well-established risk of QT prolongation and torsade de pointes (TdP), and electrolyte imbalances (e.g., hypokalemia, hypocalcemia, hypomagnesemia) may increase the risk of life-threatening arrhythmias. Pimozide is contraindicated in patients with known hypokalemia or hypomagnesemia. Topical corticosteroids are less likely to interact.
    Pioglitazone; Glimepiride: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Pioglitazone; Metformin: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Potassium Chloride: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    Potassium Phosphate; Sodium Phosphate: (Moderate) Use sodium phosphate cautiously with corticosteroids, especially mineralocorticoids or corticotropin, ACTH, as concurrent use can cause hypernatremia.
    Potassium: (Moderate) Corticotropin can cause alterations in serum potassium levels. The use of potassium salts or supplements would be expected to alter the effects of corticotropin on serum potassium levels. Also, there have been reports of generalized tonic-clonic seizures and/or loss of consciousness associated with use of bowel preparation products in patients with no prior history of seizure disorder. Therefore, magnesium sulfate; potassium sulfate; sodium sulfate should be administered with caution during concurrent use of medications that lower the seizure threshold such as systemic corticosteroids.
    Potassium-sparing diuretics: (Minor) The manufacturer of spironolactone lists corticosteroids as a potential drug that interacts with spironolactone. Intensified electrolyte depletion, particularly hypokalemia, may occur. However, potassium-sparing diuretics such as spironolactone do not induce hypokalemia. In fact, hypokalemia is one of the indications for potassium-sparing diuretic therapy. Therefore, drugs that induce potassium loss, such as corticosteroids, could counter the hyperkalemic effects of potassium-sparing diuretics.
    Pramlintide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Prasterone, Dehydroepiandrosterone, DHEA (Dietary Supplements): (Moderate) Corticosteroids blunt the adrenal secretion of endogenous DHEA and DHEAS, resulting in reduced DHEA and DHEAS serum concentrations.
    Prasterone, Dehydroepiandrosterone, DHEA (FDA-approved): (Moderate) Corticosteroids blunt the adrenal secretion of endogenous DHEA and DHEAS, resulting in reduced DHEA and DHEAS serum concentrations.
    Prilocaine; Epinephrine: (Moderate) Corticosteroids may potentiate the hypokalemic effects of epinephrine.
    Promethazine; Phenylephrine: (Moderate) The therapeutic effect of phenylephrine may be increased in patient receiving corticosteroids, such as hydrocortisone. Monitor patients for increased pressor effect if these agents are administered concomitantly.
    Propranolol: (Moderate) Patients receiving corticosteroids during propranolol therapy may be at increased risk of hypoglycemia due to the loss of counter-regulatory cortisol response. This effect may be more pronounced in infants and young children. If concurrent use is necessary, carefully monitor vital signs and blood glucose concentrations as clinically indicated.
    Propranolol; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required. (Moderate) Patients receiving corticosteroids during propranolol therapy may be at increased risk of hypoglycemia due to the loss of counter-regulatory cortisol response. This effect may be more pronounced in infants and young children. If concurrent use is necessary, carefully monitor vital signs and blood glucose concentrations as clinically indicated.
    Purine analogs: (Minor) Concurrent use of purine analogs with other agents which cause bone marrow or immune suppression such as other antineoplastic agents or immunosuppressives may result in additive effects.
    Pyridostigmine: (Moderate) Concomitant use of anticholinesterase agents. such as pyridostigmine, and corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, anticholinesterase agents should be withdrawn at least 24 hours before initiating corticosteroid therapy.
    Quetiapine: (Moderate) Use caution when administering quetiapine with corticosteroids. QT prolongation has occurred during concurrent use of quetiapine and medications known to cause electrolyte imbalance (i.e. corticosteroids).
    Quinapril; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Rapacuronium: (Moderate) Limit the period of use of neuromuscular blockers and corticosteroids and only use when the specific advantages of the drugs outweigh the risks for acute myopathy. An acute myopathy has been observed with the use of high doses of corticosteroids in patients receiving concomitant long-term therapy with neuromuscular blockers. Clinical improvement or recovery after stopping therapy may require weeks to years.
    Regular Insulin: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    Repaglinide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Ritodrine: (Major) Ritodrine has caused maternal pulmonary edema, which appears more often in patients treated concomitantly with corticosteroids. Patients so treated should be closely monitored in the hospital.
    Rituximab: (Moderate) Rituximab and corticosteroids are commonly used together; however, monitor the patient for immunosuppression and signs and symptoms of infection during combined chronic therapy.
    Rituximab; Hyaluronidase: (Moderate) Rituximab and corticosteroids are commonly used together; however, monitor the patient for immunosuppression and signs and symptoms of infection during combined chronic therapy.
    Rocuronium: (Moderate) Limit the period of use of neuromuscular blockers and corticosteroids and only use when the specific advantages of the drugs outweigh the risks for acute myopathy. An acute myopathy has been observed with the use of high doses of corticosteroids in patients receiving concomitant long-term therapy with neuromuscular blockers. Clinical improvement or recovery after stopping therapy may require weeks to years.
    Salicylates: (Moderate) Salicylates or NSAIDs should be used cautiously in patients receiving corticosteroids. While there is controversy regarding the ulcerogenic potential of corticosteroids alone, concomitant administration of corticosteroids with aspirin may increase the GI toxicity of aspirin and other non-acetylated salicylates. Withdrawal of corticosteroids can result in increased plasma concentrations of salicylate and possible toxicity. Concomitant use of corticosteroids may increase the risk of adverse GI events due to NSAIDs. Although some patients may need to be given corticosteroids and NSAIDs concomitantly, which can be done successfully for short periods of time without sequelae, prolonged coadministration should be avoided.
    Salsalate: (Moderate) Salicylates or NSAIDs should be used cautiously in patients receiving corticosteroids. While there is controversy regarding the ulcerogenic potential of corticosteroids alone, concomitant administration of corticosteroids with aspirin may increase the GI toxicity of aspirin and other non-acetylated salicylates. Withdrawal of corticosteroids can result in increased plasma concentrations of salicylate and possible toxicity. Concomitant use of corticosteroids may increase the risk of adverse GI events due to NSAIDs. Although some patients may need to be given corticosteroids and NSAIDs concomitantly, which can be done successfully for short periods of time without sequelae, prolonged coadministration should be avoided.
    Sargramostim, GM-CSF: (Major) Avoid the concomitant use of sargramostim and systemic corticosteroid agents due to the risk of additive myeloproliferative effects. If coadministration of these drugs is required, frequently monitor patients for clinical and laboratory signs of excess myeloproliferative effects (e.g., leukocytosis). Sargramostim is a recombinant human granulocyte-macrophage colony-stimulating factor that works by promoting proliferation and differentiation of hematopoietic progenitor cells.
    Semaglutide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    SGLT2 Inhibitors: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Sodium Benzoate; Sodium Phenylacetate: (Moderate) Corticosteroids may cause protein breakdown, which could lead to elevated blood ammonia concentrations, especially in patients with an impaired ability to form urea. Corticosteroids should be used with caution in patients receiving treatment for hyperammonemia.
    Sodium Chloride: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    Sodium Phenylbutyrate: (Moderate) The concurrent use of corticosteroids with sodium phenylbutyrate may increase plasma ammonia levels (hyperammonemia) by causing the breakdown of body protein. Patients with urea cycle disorders being treated with sodium phenylbutyrate usually should not receive regular treatment with corticosteroids.
    Sodium Phosphate Monobasic Monohydrate; Sodium Phosphate Dibasic Anhydrous: (Moderate) Use sodium phosphate cautiously with corticosteroids, especially mineralocorticoids or corticotropin, ACTH, as concurrent use can cause hypernatremia.
    Somatropin, rh-GH: (Moderate) Corticosteroids can retard bone growth and therefore, can inhibit the growth-promoting effects of somatropin. If corticosteroid therapy is required, the corticosteroid dose should be carefully adjusted.
    Spironolactone; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Succinylcholine: (Moderate) Limit the period of use of neuromuscular blockers and corticosteroids and only use when the specific advantages of the drugs outweigh the risks for acute myopathy. An acute myopathy has been observed with the use of high doses of corticosteroids in patients receiving concomitant long-term therapy with neuromuscular blockers. Clinical improvement or recovery after stopping therapy may require weeks to years.
    Sulfonylureas: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Telbivudine: (Moderate) The risk of myopathy may be increased if corticosteroids are coadministered with telbivudine. Monitor patients for any signs or symptoms of unexplained muscle pain, tenderness, or weakness, particularly during periods of upward dosage titration.
    Telmisartan; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Testosterone: (Moderate) Coadministration of corticosteroids and testosterone may increase the risk of edema, especially in patients with underlying cardiac or hepatic disease. Corticosteroids with greater mineralocorticoid activity, such as fludrocortisone, may be more likely to cause edema. Administer these drugs in combination with caution.
    Thiazide diuretics: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.

Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Thyroid hormones: (Moderate) The metabolism of corticosteroids is increased in hyperthyroidism and decreased in hypothyroidism. Dosage adjustments may be necessary when initiating, changing or discontinuing thyroid hormones or antithyroid agents.
    Tobramycin: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    Tolazamide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Tolbutamide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
    Tositumomab: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
    Tranexamic Acid: (Moderate) Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
    Tretinoin, ATRA: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
    Triamterene; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.
    Tuberculin Purified Protein Derivative, PPD: (Moderate) Immunosuppressives may decrease the immunological response to tuberculin purified protein derivative, PPD. This suppressed reactivity can persist for up to 6 weeks after treatment discontinuation. Consider deferring the skin test until completion of the immunosuppressive therapy.
    Tubocurarine: (Moderate) Limit the period of use of neuromuscular blockers and corticosteroids and only use when the specific advantages of the drugs outweigh the risks for acute myopathy. An acute myopathy has been observed with the use of high doses of corticosteroids in patients receiving concomitant long-term therapy with neuromuscular blockers. Clinical improvement or recovery after stopping therapy may require weeks to years.
    Valsartan; Hydrochlorothiazide, HCTZ: (Moderate) Additive hypokalemia may occur when non-potassium sparing diuretics, including thiazide diuretics, are coadministered with other drugs with a significant risk of hypokalemia, such as corticosteroids. Monitoring serum potassium levels and cardiac function is advised, and potassium supplementation may be required.

Clinical improvement or recovery after stopping therapy may require weeks to years.
    Vigabatrin: (Major) Vigabatrin should not be used with corticosteroids, which are associated with serious ophthalmic effects (e.g., retinopathy or glaucoma) unless the benefit of treatment clearly outweighs the risks.
    Vincristine Liposomal: (Moderate) Use sodium phosphate cautiously with corticosteroids, especially mineralocorticoids or corticotropin, ACTH, as concurrent use can cause hypernatremia.
    Voriconazole: (Moderate) Monitor for potential adrenal dysfunction with concomitant use of voriconazole and beclomethasone. In patients taking corticosteroids, voriconazole-associated CYP3A4 inhibition of their metabolism may lead to corticosteroid excess and adrenal suppression. Corticosteroid exposure is likely to be increased. Voriconazole is a strong CYP3A4 inhibitor, and beclomethasone is a CYP3A4 substrate.
    Vorinostat: (Moderate) Use vorinostat and corticosteroids together with caution; the risk of QT prolongation and arrhythmias may be increased if electrolyte abnormalities occur. Corticosteroids may cause electrolyte imbalances; hypomagnesemia, hypokalemia, or hypocalcemia and may increase the risk of QT prolongation with vorinostat. Frequently monitor serum electrolytes if concomitant use of these drugs is necessary.
    Warfarin: (Moderate) Monitor the INR if warfarin is administered with corticosteroids. The effect of corticosteroids on warfarin is variable. There are reports of enhanced as well as diminished effects of anticoagulants when given concurrently with corticosteroids; however, limited published data exist, and the mechanism of the interaction is not well described. High-dose corticosteroids appear to pose a greater risk for increased anticoagulant effect. In addition, corticosteroids have been associated with a risk of peptic ulcer and gastrointestinal bleeding.
    Zafirlukast: (Minor) Zafirlukast inhibits the CYP3A4 isoenzymes and should be used cautiously in patients stabilized on drugs metabolized by CYP3A4, such as corticosteroids.

    PREGNANCY AND LACTATION

    Pregnancy

    Corticosteroids distribute into breast-milk in low concentrations; according to FDA-approved product labels of beclomethasone, caution should be exercised when administering beclomethasone to women who are breast-feeding. Beclomethasone via inhaled administration typically results in low systemic concentrations; therefore, the amount excreted into breast-milk after inhalation is expected to be very low. Reviewers and an expert panel consider inhaled and oral corticosteroids acceptable to use during breast-feeding. Low-dose inhaled corticosteroids are considered first line therapy for control of mild persistent asthma during pregnancy and lactation according to the National Asthma Education and Prevention Program (NAEPP) Asthma and Pregnancy Working Group. Due to greater availability of data in pregnancy, budesonide is the preferred agent in this population. However, there are no data to indicate safety concerns with other inhaled corticosteroids and maintaining a previously established treatment regimen may be more beneficial to the patient. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally administered drug, healthcare providers are encouraged to report the adverse effect to the FDA.

    MECHANISM OF ACTION

    Beclomethasone is a corticosteroid that exhibits anti-inflammatory, antipruritic, vasoconstrictive effects as well as limiting allergic responses. The specific mechanisms of action depend on the route of administration and condition being treated.
     
    Treatment of asthma:
    Clinical effects in asthma include a reduction in bronchial hyperresponsiveness to allergens, a decreased number of asthma exacerbations, and an improvement in FEV1, peak-flow rate, and respiratory symptoms. Because corticosteroid effects take several hours to days to become clinically noticeable, they are ineffective for primary treatment of severe acute bronchospastic attacks or for status asthmaticus. Inhaled corticosteroids have no bronchodilatory properties. In the treatment of asthma, orally inhaled corticosteroids block the late phase allergic response to allergens. Mediators involved in the pathogenesis of asthma include histamine, leukotrienes (the slow-releasing substance of anaphylaxis, SRS-A), eosinophil chemotactic factor of anaphylaxis (ECF-A), neutrophil chemotactic factor (NCF), cytokines, hydroxyeicosatetraenoic acids, prostaglandin-generating factor of anaphylaxis (PGF-A), prostaglandins, major basic protein, bradykinin, adenosine, peroxides, and superoxide anions. Different cell types are responsible for the release of these mediators including airway epithelium, eosinophils, basophils, lung parenchyma, lymphocytes, macrophages, mast cells, neutrophils, and platelets. Corticosteroids inhibit the release of these mediators, attenuate mucous secretion and eicosanoid generation, up-regulate beta-receptors, promote vasoconstriction, and suppress inflammatory cell influx and inflammatory processes.
     
    Treatment of allergies:
    Intranasal beclomethasone inhibits the activity of several cell types (e.g., mast cells and eosinophils) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in the allergic response. Clinically, symptoms such as rhinorrhea and postnasal drip, nasal congestion, sneezing, and pharyngeal itching are reduced. In vitro data have shown that beclomethasone-17-monopropionate (the active entity) displays a binding affinity for the glucocorticoid receptor that is approximately 13 times that of dexamethasone, 6 times that of triamcinolone acetonide, 1.5 times that of budesonide, and 25 times that of beclomethasone dipropionate (the prodrug).

    PHARMACOKINETICS

    Beclomethasone is administered by oral or nasal inhalation.
     
    The major route of elimination of inhaled beclomethasone appears to be via metabolism. Three major metabolites of beclomethasone are formed via hepatic cytochrome P450 3A-family catalyzed biotransformation: beclomethasone-17-monopropionate (17-BMP, the most active metabolite), beclomethasone-21-monopropionate (21-BMP) and beclomethasone (BOH). More than 90% of inhaled beclomethasone is found as 17-BMP in the systemic circulation. For the oral inhalation route, some metabolism occurs in the lungs before entering the systemic circulation; the lung tissues metabolize beclomethasone rapidly to 17-BMP and more slowly to BOH. The mean elimination half-life of 17-BMP is 2.8 hours; the biological half-life of beclomethasone is roughly 15 hours. Irrespective of the route of administration (injection, oral, or inhalation), beclomethasone and its metabolites are excreted predominantly in the feces. Less than 10% of the drug and its metabolites are excreted in the urine.

    Inhalation Route

    Nasal inhalation absorption: After nasal inhalation, beclomethasone is absorbed through the nasal mucosa, with minimal amounts absorbed systemically. Approximately 10% to 25% of a nasally administered dose enters the respiratory tract, while a portion of the dose that is deposited into the mouth and oropharynx and is swallowed.
    Oral inhalation absorption (Qvar): After oral inhalation, roughly 50% to 60% of the administered dose reaches the respiratory tract. The onset of action of the drug typically occurs within 24 hours, but full effects can take as long as 1 to 4 weeks to be apparent. The mean peak plasma concentration (Cmax) was 88 pg/mL and occurred 30 minutes after inhalation of 320 mcg (4 puffs of the 80 mcg/actuation strength). The mean Cmax of the major and most active metabolite, 17-BMP, occurs roughly 0.7 hour after inhalation of the same dosage. When the same nominal dose is provided by the two strengths (40 and 80 mcg/actuation), equivalent systemic pharmacokinetics can be expected. The Cmax of 17-BMP increases proportionally with dose in the normal dosage range.
    Oral inhalation absorption (Qvar Redihaler): After oral inhalation, the onset of action of the drug typically occurs within 24 hours, but full effects can take as long as 3 to 4 weeks to be apparent. The mean peak plasma concentration (Cmax) was 6,635 pg/mL at 2 minutes after inhalation of 320 mcg (4 inhalations of the 80 mcg/inhalation strength). The mean Cmax of the major and most active metabolite, 17-BMP, was 1,464 pg/mL at 10 minutes after inhalation of 320 mcg.
