Mycophenolic Acid Accord Healthcare (Mycophenolic Acid)

Mycophenolic Acid is an immunosuppressant that acts on lymphocyte proliferation to protect transplanted organs.

• Kidney transplant: prevents acute rejection and supports long‑term graft function.
• Heart transplant: reduces the risk of early rejection episodes.
• Liver transplant: helps maintain graft viability and reduces rejection rates.
• Maintenance therapy: sustains graft health after the initial post‑operative period.

• Mycophenolic Acid reversibly inhibits inosine monophosphate dehydrogenase (IMPDH), the key enzyme for guanosine nucleotide synthesis in lymphocytes. By depleting guanosine pools, it selectively suppresses proliferation of T and B cells, thereby reducing immune‑mediated graft rejection while sparing other cell types.

Adverse reactions may occur with mycophenolic acid therapy.

Common Side Effects

• Nausea: mild to moderate gastrointestinal upset.
• Diarrhea: frequent loose stools.
• Vomiting: occasional emesis.
• Abdominal pain: cramping or discomfort.
• Headache: transient mild headache.
• Infections: increased susceptibility to common infections.

Serious or Rare Side Effects

• Leukopenia: significant reduction in white blood cells.
• Anemia: decreased red blood cell count.
• Severe infections: opportunistic or life‑threatening infections.
• Malignancy: increased risk of certain cancers.
• Hepatic dysfunction: elevated liver enzymes or hepatitis.
• Progressive multifocal leukoencephalopathy (PML): rare demyelinating disease.

Patients receiving mycophenolic acid should be monitored closely for safety.

• Monitor blood counts: regular CBC to detect leukopenia or anemia.
• Monitor renal function: assess creatinine and eGFR periodically.
• Avoid use in uncontrolled infection: defer therapy until infection is treated.
• Adjust dose in hepatic impairment: consider reduced dosing if liver function is compromised.
• Counsel on contraception: advise effective birth control due to unknown pregnancy safety.
• Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Mycophenolic acid can interact with several medicines; some require avoidance while others need careful monitoring.

Major Interactions (Avoid)

• Azathioprine: additive bone‑marrow suppression.
• Cyclosporine: increased mycophenolic acid exposure.
• Tacrolimus: heightened immunosuppressive effect.
• Live vaccines: risk of severe infection.
• Cholestyramine: reduces oral absorption.

Moderate Interactions (Monitor Closely)

• Antacids (aluminum or magnesium): may lower absorption.
• NSAIDs: potential for renal impairment.
• Warfarin: may alter anticoagulant effect.
• Ribavirin: increased hematologic toxicity.
• Fluconazole: modest increase in mycophenolic acid levels.
