What Are Warnings and Precautions for Mycophenolate?

Warnings

Increased susceptibility to infection as consequence of immunosuppression.

Drug should be prescribed only by healthcare providers experienced in immunosuppressive therapy and management of renal, cardiac, or hepatic transplant patients.

Patients receiving drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources.

Drug increases risk of developing lymphoma and risk of skin malignancy.

Myfortic and CellCept dosage form absorbed differently; not for use interchangeably.

Healthcare provider responsible for maintenance therapy should have all information required for follow-up.

Risk of first-trimester miscarriage and congenital malformations; after negative pregnancy test and follow-up, women of child-bearing age should use 2 forms of reliable contraception (hormone plus barrier) during entire course of mycophenolate therapy and continue until 6 weeks after drug discontinuation.

This medication contains mycophenolate. Do not take CellCept, Myfortic, or MMF if you are allergic to mycophenolate or any ingredients contained in this drug.

Keep out of reach of children. In case of overdose, get medical help or contact a Poison Control Center immediately.

Contraindications

  • Hypersensitivity
  • Intravenous (IV) formulation (CellCept) in patients allergic to polysorbate 80

Long-Term Effects

Cautions

Pure red-cell aplasia reported in patients treated with MMF or MPA in combination with other immunosuppressive agents.

Avoid use in hypoxanthine-guanine phosphoribosyltransferase (HGPRT) deficiency (Lesch-Nyhan, Kelley-Seegmiller syndrome).

Risk of miscarriage and congenital malformations, especially external ear and other facial abnormalities including cleft lip and palate, and anomalies of the distal limbs, heart, esophagus, kidney and nervous system (see Warnings).

MMF oral suspension contains aspartame.

MPA not indicated for hepatic or cardiac transplants.

Use may be rarely associated with gastric or duodenal ulcers, gastrointestinal (GI) bleeding and/or perforation.

Safety and effectiveness of MPA for de novo pediatric renal transplant not established.

Neutropenia may occur (may require dose reduction).

Must not be administered by rapid or bolus intravenous (IV) injection.

Toxicity may increase in renal impairment; use caution.

Serious infections and viral reactivation:

  • Increased risk of developing bacterial, fungal, protozoal, and new or reactivated viral infections, including opportunistic infections
  • Because of danger of oversuppression of immune system, which can increase susceptibility to infection, combination immunosuppressant therapy should be used with caution
  • May increase risk of new or reactivated viral infections, including polyomavirus-associated nephropathy (PVAN), JC virus-associated progressive multifocal leukoencephalopathy (PML), cytomegalovirus (CMV) infections, and reactivation of hepatitis B or C
  • PVAN, especially when due to BK virus infection, is associated with serious outcomes, including deteriorating renal function and renal graft loss
  • PML, which is sometimes fatal, typically presents with hemiparesis, apathy, confusion, cognitive deficiencies, and ataxia

Pregnancy and Lactation

  • Use mycophenolate during pregnancy only in LIFE-THREATENING emergencies when no safer drug is available. There is positive evidence of human fetal risk.
  • Mycophenolate can cause fetal harm when administered to pregnant females. Use of MMF during pregnancy is associated with an increased risk of first trimester pregnancy loss and increased risk of congenital malformations, especially external ear and other facial abnormalities including cleft lip and palate, and anomalies of distal limbs, heart, esophagus, kidney and nervous system.
  • It is unknown whether mycophenolate is excreted in breast milk; avoid using mycophenolate, or do not nurse.
