Lupus Medications – CellCept (mycophenolate mofetil)


Updated June 11, 2014

What is CellCept?:

CellCept (mycophenolate mofetil, or MMF) is an immunosuppressant often used in patients with lupus nephritis (in which the disease attacks the kidneys). Immunosuppresives are used in the treatment of lupus because:

  • They are potent drugs and help control disease activity in major organs, and,
  • May reduce or eliminate the need for steroids.
It is available only by prescription.

It should be noted that MMF has been shown to significantly reduce steroid dosage for patients with lupus nephritis or treatment-resistant systemic lupus erythematosus, and is considered a first-line therapy for lupus nephritis, often replacing cyclophosphamide.

How does it work?:

As an immunosuppressive, it works by weakening the body's immune system so it will not produce auto-antibodies. The immune system of lupus patients produces auto-antibodies at a rapid rate, which in turn attack the immune system. When this happens, victims can suffer inflammation (the primary feature of lupus), pain, and tissue damage.

Who shouldn’t take, or should check with their doctor before taking CellCept?:

  • Pregnant and nursing mothers
  • Those planning to have children (both women and men)
    • Note: On Oct. 29, 2007, Roche, which manufactures CellCept, and the FDA notified healthcare providers that use of MMF is associated with increased risk of first trimester pregnancy loss and increased risk of congenital malformations, especially external ear and facial abnormalities including cleft lip and palate, and anomalies of the distal limbs, heart, esophagus, and kidney. The pregnancy category for MMF has been changed from Category C (risk of fetal harm cannot be ruled out) to Category D (positive evidence of fetal risk).
  • Those taking acetazolamide, acyclovir, antibiotics; azathioprine, chlorothiazide, cimetidine, cholestyramine, colestipol, ethacrynic acid, furosemide, ganciclovir, isoproterenol, meperidine, morphine, oral contraceptives, phenytoin, probenecid, procainamide, quinine, salicylate pain relievers, choline magnesium trisalicylate, choline salicylate, diflunisal, magnesium salicylate and salsalate, and theophylline.
  • Those who suffer from liver or kidney disease
  • Those who suffer from Lsech-Nyhan or Keeley-Seegmiller Syndrome
