Route & Dosage

Note: CellCept and Myfortic are not interchangeable.

Prophylaxis for Kidney Transplant Rejection
Adult: PO/IV Start within 24 h of transplant, 1 g (mofetil) or 720 mg (sodium) b.i.d. in combination with corticosteroids and cyclosporine
Child: PO 600 mg/m2 (mofetil) or 400 mg/m2 (sodium) b.i.d. (max: 2 g/d mofetil, 720 mg/d sodium)

Prophylaxis for Heart/Liver Transplant Rejection
Adult: PO/IV 1.5 g (mofetil) b.i.d. started within 24 h of transplant


  • Give oral drug on an empty stomach.
  • Adjust dosage with severe chronic kidney failure.
  • Do not open or crush capsules; avoid contact with powder in capsules, and wash thoroughly with soap and water if contact occurs.

PREPARE: IV Infusion: Reconstitute each vial with 14 mL D5W. Further dilute each 500 mg in an additional 70 mL of D5W to yield 6 mg/mL.  

ADMINISTER: IV Infusion: Slowly infuse over ≥2 h. Avoid rapid injection.  

INCOMPATIBILITIES Solution/additive & Y-site: Do not mix or infuse with other medications.

  • Begin IV mycophenolate mofetil within 24 h of transplant and continued for up to 14 d.
  • Switch patient to oral drug as soon as possible.
  • Store at 15°–30° C (59°–86° F).

Adverse Effects (≥1%)

CNS: Headache, tremor, insomnia, dizziness, weakness. CV: Hypertension. Endocrine: Hyperglycemia, hypercholesterolemia, hypophosphatemia, hypokalemia, hyperkalemia, peripheral edema. GI: Diarrhea, constipation, nausea, anorexia, vomiting, abdominal pain, dyspepsia. Urogenital: UTI, hematuria, renal tubular necrosis, burning, frequency, vaginal burning or itching, vaginal bleeding, kidney stones. Hematologic: Leukopenia, anemia, thrombocytopenia, hypochromic anemia, leukocytosis. Respiratory: Respiratory infection, dyspnea, increased cough, pharyngitis. Skin: Rash. Body as a Whole: Leg or hand cramps, bone pain, myalgias, sepsis (bacterial, fungal, viral).


Drug: Acyclovir, ganciclovir may increase mycophenolate serum levels. antacids, cholestyramine decreases mycophenolate absorption. Mycophenolate may decrease protein binding of phenytoin or theophylline, causing increased serum levels.


Absorption: Rapidly from GI tract; 94% reaches systemic circulation; absorption decreased by food. Onset: 4 wk. Metabolism: In liver to active form, mycophenolic acid. Elimination: 87% in urine. Half-Life: 11 h.

Nursing Implications

Assessment & Drug Effects

  • Prior to initiating therapy: baseline CBC with differential.
  • Withold dose and notify physician if neutropenia develps (ANC <1.3 x 103/mcL).
  • Lab tests: Monitor CBC weekly for first month, biweekly for second and third months, then once per month for first year; periodic kidney function tests, LFTs, serum electrolytes, lipase, amylase, blood glucose, and routine urinalysis.
  • Monitor for and report any S&S of sepsis or infection.

Patient & Family Education

  • Comply exactly with dosing regimen and scheduled laboratory tests.
  • Report to physician immediately S&S of infection, such as UTI or respiratory infection, or signs of bleeding (e.g., black tarry stools, blood in urine, easy bruising).
  • Report all troubling adverse reactions (e.g., blood in urine and swelling in arms and legs) to physician as soon as possible.
  • Avoid taking OTC antacids simultaneously with mycophenolate mofetil. Separate the two drugs by 2 h.
  • Women should use effective contraception during and for 6 wk after treatment is completed.
