Micofenolato De Mofetilo Tillomed (Mycophenolate Mofetil)

Mycophenolate Mofetil acts on the immune system to inhibit lymphocyte proliferation, making it useful in several immunologically mediated conditions.

• Prevention of organ transplant rejection: lowers the risk of acute and chronic graft rejection after kidney, heart or liver transplantation.
• Treatment of lupus nephritis: reduces renal inflammation and helps preserve kidney function in systemic lupus erythematosus.
• Management of certain autoimmune diseases: suppresses immune activity in disorders such as vasculitis or dermatomyositis.

• Mycophenolate Mofetil is converted intracellularly to mycophenolic acid, which selectively inhibits inosine monophosphate dehydrogenase (IMPDH). This blockade reduces guanosine nucleotide synthesis, a pathway essential for the proliferation of T and B lymphocytes, thereby dampening the adaptive immune response while sparing other cell types.

Adverse reactions may vary in frequency and severity.

Common Side Effects

• Nausea: mild to moderate upset stomach.
• Diarrhea: increased bowel movements, sometimes watery.
• Headache: transient cranial discomfort.
• Abdominal pain: cramping or discomfort in the stomach area.
• Infections: higher susceptibility to common viral or bacterial infections.

Serious or Rare Side Effects

• Leukopenia: significant reduction in white blood cells.
• Severe infections: opportunistic infections such as Pneumocystis jirovecii pneumonia.
• Hepatotoxicity: elevated liver enzymes or liver injury.
• Malignancy risk: increased incidence of certain cancers with long‑term use.
• Progressive multifocal leukoencephalopathy (PML): rare demyelinating disease of the brain.

Patients should be monitored closely for safety concerns before and during therapy.

• Monitor blood counts: regular CBC to detect leukopenia or anemia.
• Monitor liver function: periodic LFTs to identify hepatotoxicity.
• Avoid in pregnancy: drug is contraindicated; effective contraception required.
• Use caution in renal impairment: dose adjustment may be needed.
• Counsel on infection risk: advise prompt reporting of fever or signs of infection.
• Store at room temperature: keep in original packaging, protect from moisture and direct sunlight.

Mycophenolate Mofetil may interact with several medicines, affecting efficacy or safety.

Major Interactions (Avoid)

• Live vaccines: may cause uncontrolled infection.
• Strong CYP3A4 inducers (e.g., rifampin, carbamazepine): markedly reduce drug exposure.
• Antacids containing aluminum or magnesium: decrease absorption if taken simultaneously.

Moderate Interactions (Monitor Closely)

• Other immunosuppressants (e.g., azathioprine, tacrolimus): increase risk of bone marrow suppression.
• ACE inhibitors or ARBs: may worsen renal function when combined.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): elevate risk of kidney injury.
• Vaccines (non‑live): monitor immune response effectiveness.
