FDA Box Warning
• Increased susceptibility to infection and possible lymphoma development may result from immunosuppression. Give drug under supervision of physician experienced in immunosuppressive therapy and management of renal, cardiac, or hepatic transplant patients, in facility with adequate diagnostic and treatment resources. Physician responsible for maintenance therapy should have complete information needed for patient follow-up.
• Use of CellCept during pregnancy is associated with increased risk of pregnancy loss and congenital malformations. Female patients of childbearing potential who are taking CellCept must use contraception.
Inhibits binding of interleukin (IL)-1 to IL-1 receptors, preventing proliferation and differentiation of activated B and T cells. Binds to intracellular proteins to prevent T-cell activation, suppressing immune responses.

• Severe chronic renal impairment
• Hypersensitivity to drug or its components, mycophenolic acid, or polysorbate 80 (I.V. form)
Use cautiously in:
• lymphoma, cancer, neutropenia, renal disease, or GI disorders
• elderly patients
• pregnant or breastfeeding patients
• children (indicated for kidney transplant only).
• Give P.O. form at least 1 hour before or 2 hours after meals. To enhance absorption, don't give with other drugs.
• Give delayed-released tablets whole. Don't let patient crush or chew them.
• Know that pharmacist should mix oral solution before dispensing.

Drug-drug. Acyclovir, ganciclovir, other drugs that undergo renal tubular secretion: increased risk of toxicity from either drug
Antacids containing aluminum or magnesium: decreased mycophenolate absorption
Cholestyramine: reduced mycophenolate bioavailability
Hormonal contraceptives: reduced contraceptive efficacy
Phenytoin, theophylline: increased blood levels of both drugs
Probenecid, salicylates: increased mycophenolate blood level
Drug-diagnostic tests. Cholesterol: increased level
Drug-herbs. Astragalus, echinacea, melatonin: interference with immunosuppressant effect
• Monitor CBC with white cell differential, electrolyte levels, lipid panel, blood chemistry, and liver function tests frequently.
• Evaluate vital signs. Assess cardiovascular and respiratory status carefully. Watch for signs and symptoms of bronchitis and pneumonia.
☞ Assess all body systems carefully for signs and symptoms of infection.
☞ Monitor patient closely for bleeding tendency.
• Advise patient to take oral drug at least 1 hour before or 2 hours after meals. Tell him not to crush, break, or chew tablets, not to open or chew capsules, and not to take with other drugs.

☞ Instruct patient to take his temperature and promptly report fever or other signs or symptoms of infection. Tell him to immediately report unusual bleeding or bruising.
• Caution patient to avoid driving and other hazardous activities until he knows how drug affects concentration and alertness.
• Instruct patient to avoid crowds and people with known infections.

mycophenolate mofetilA mycophenolic ester used as a therapeutic immunosuppressant, which is similar to, but less toxic than, azathioprine. Mycophenolate mofetil inhibits purine metabolism in T and B cells, and lymphocyte proliferation in vitro.
Prevent or manage GVHD, rejection of heart, kidney, lung and other allograft transplants, autoimmune disorders (e.g., Behçet disease, pemphigus vulgaris, systemic lupus erythematosus).
Hyperglycaemia, hypercholesterolaemia, increased BUN, potassium, leukopaenia, anaemia, diarrhoea, emesis.
