FDA Issues an FDA Alert and Information for Healthcare Professional Sheet for Mycophenolate Mofetil (CellCept) and Mycophenolic Acid (Myfortic)

May 16, 2008--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. In most cases, the mothers were taking MMF following an organ transplant to prevent organ rejection. However, some mothers taking MMF were being treated for immune-mediated conditions such as systemic lupus erythematosus (SLE) and erythema multiforme. Treatment began before their pregnancies and continued into the first trimester or until the pregnancy was detected. MMF is approved in the U.S. for use in the prophylaxis of organ rejection in patients receiving allogeneic renal, cardiac or hepatic transplants and MPA is approved in the U.S. for use in the prophylaxis of organ rejection in patients receiving allogeneic renal transplants. In patients who are transplant recipients, these drugs are almost always used in combination with other immunosuppressant drugs.
