Information for Healthcare Professionals: Mycophenolate Mofetil (marketed as CellCept) and Mycophenolic Acid (marketed as Myfortic)
This information reflects FDA's current analysis of data available to FDA concerning this drug. FDA intends to update this sheet when additional information or analyses become available.
FDA is aware of reports of infants born with serious congenital anomalies, including microtia and cleft lip and palate, following exposure to mycophenolate mofetil (MMF) during pregnancy. MMF, the active drug substance in CellCept, is an ester of the active metabolite mycophenolic acid (MPA), the active drug substance in Myfortic.
MMF and MPA increase the risk of spontaneous abortion in the first trimester and can cause congenital malformations in the offspring of women who are treated during pregnancy. The labeling for both MMF and MPA was revised in November 2007 to change the Pregnancy Category to "D" (positive evidence of human fetal risk, but potential benefits may warrant use of the drug in pregnant women despite the potential risk) and to add these findings about the risk of early pregnancy loss and congenital malformations to the Boxed Warning.
Prior to prescribing MMF or MPA, clinicians should:
- Provide information on the fetal risks.
- Provide counseling about contraception options.
- Provide instruction on the appropriate use of contraceptive methods.
- Confirm that the woman is not pregnant.
