It is not known if tolnaftate is absorbed through the epidermis nor how tolnaftate is metabolized, therefore use with caution. Quantitative recommendations are not available.
For storage information, see specific product information within the How Supplied section.
Topical tolnaftate preparations are for external use only. Do not apply to blistered, oozing, or raw skin. Do not apply to the eye or mucus membranes.Cleanse and dry affected area thoroughly prior to using topical tolnaftate preparations.Do not use dressings that do not allow air circulation over the affected area (occlusive dressings) unless otherwise directed. A light breathable dressing may be used to protect clothing.
Cream: Rub tolnaftate cream solution gently into cleansed affected skin.
Gel or solution: Rub tolnaftate gently into cleansed affected skin.Aerosol liquid or aerosol powder: Shake well before using. Spray onto cleansed affected skin. Spray evenly, at a distance of 6 to 10 inches from the infected area. If treating the feet, spray between the toes.Powder: Apply to cleansed affected skin. The powder may be used in conjunction with other preparations of tolnaftate for active treatment.Wipes or swabs: Rub wipe gently into cleansed affected skin.

Clinical studies with tolnaftate did not include sufficient numbers of elderly patients 65 years of age and older to determine whether they respond differently from younger patients; however, differences in response are not expected.
Tolnaftate should not be used in patients with known tolnaftate hypersensitivity or sensitivity to any components of the specific formulation (components can include parabens, alcohols, propylene glycol, etc., check package labels); use with caution if paraben hypersensitivity or other hypersensitivities exist. If irritation or hypersensitivity occurs or if the patient's skin disease does not improve within 10 days or becomes worse during self medication with tolnaftate, treatment should be discontinued and the patient should consult a health care provider. This drug does not treat bacterial infections or yeast infections. Use of tolnaftate is recommended only in patients who have a superficial dermatophyte infection. As with many other topical antifungal drugs, topical tolnaftate is not effective for onychomycosis; this condition usually requires treatment with an oral (systemic) antifungal drug. Tolnaftate should be used externally only. It should not be applied to the eyes (avoid ocular exposure). Tolnaftate should not be applied to blistered, oozing, or raw skin. After application, the use of an occlusive dressing is not recommended, but a breathable dressing may be used to protect the area and clothing. Keep preparations containing alcohol or packaged with contents under pressure away from open flames or heat due to flammability; do not use while tobacco smoking.
Tolnaftate should not be used for self-treatment in patients with immunosuppression or patients with diabetes mellitus or peripheral vascular disease. Fungi are more likely to penetrate the dermal layer and cause systemic infection in these patient populations. A health care provider should be consulted for evaluation of the condition before treatment.
Safe and effective use of tolnaftate for self treatment in neonates, infants and children < 2 years and infants has not been established; consult a health care provider before use.
Tolnaftate has not been assigned a specific FDA pregnancy risk category rating. Its absorption through the epidermis and potential effects on the fetus and reproductive capacity are unknown. As with any drug in pregnancy, use only under the advise of a physician (not for self medication).
Data are limited regarding use of tolnaftate during breast-feeding, and its excretion in human milk is unknown. Following topical application, it is poorly absorbed and likely poses low risk to a nursing infant. To minimize potential infant exposure, instruct patients to avoid topical application to the breast. 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, health care providers are encouraged to report the adverse effect to the FDA.

There are no drug interactions associated with Tolnaftate products.
Mechanism of Action: Tolnaftate, like naftifine and terbinafine, is a reversible and noncompetitive inhibitor of fungal squalene epoxidase. The membrane bound epoxidase plays a key role in the biosynthetic pathway from acetate to sterols. The blockade of this enzyme results in the accumulation of squalene and a deficiency of ergosterol. Tolnaftate has been shown to distort hyphae and stunt mycelial growth in susceptible fungi. Resistance to tolnaftate has been reported only rarely. However, the potential to develop resistance by the action of multidrug efflux transporters does exist. Tolnaftate is fungistatic or fungicidal depending on its concentration at the site of infection and the specific susceptibility of the organism.Tolnaftate, compared to naftifine and terbinafine, is the least effective topical antimycotic. In general, tolnaftate is active against the following organisms in vitro: Microsporum gypseum, M. canis, M. audouinii, M. japonicum, Trichophyton rubrum, T. mentagrophytes, T. schoenleinii, T tonsurans, and Epidermophyton floccosum. Tolnaftate is ineffective against Candida albicans, Cryptococcus neoformans, and Aspergillus fumigatus.
Tolnaftate is applied topically. There are no data available on the pharmacokinetics of tolnaftate. It is unknown if tolnaftate is absorbed through the epidermis or if detectable systemic concentrations of tolnaftate are achieved in the blood.
