Indications & Clinical Uses

Azathioprine is used across several immune‑mediated disease categories to modulate overactive lymphocyte activity.

  • Organ transplantation: helps prevent graft rejection by suppressing immune response.
  • Rheumatoid arthritis: reduces joint inflammation and slows disease progression.
  • Inflammatory bowel disease: maintains remission in Crohn’s disease and ulcerative colitis.
  • Systemic lupus erythematosus: diminishes systemic inflammation and autoantibody production.

How It Works

  • Azathioprine is an antimetabolite that is converted intracellularly to 6‑mercaptopurine, which interferes with purine nucleotide synthesis. This disruption hampers DNA replication in rapidly dividing lymphocytes, leading to reduced proliferation of T and B cells and overall immunosuppression.

Side Effects

Azathioprine may cause a range of adverse reactions, from mild to severe.

Common Side Effects

  • Nausea or vomiting: gastrointestinal upset occurring shortly after dosing.
  • Leukopenia: reduced white blood cell count that may increase infection risk.
  • Elevated liver enzymes: mild hepatic enzyme rise detectable on routine labs.

Serious or Rare Side Effects

  • Bone marrow aplasia: profound suppression of blood cell production requiring immediate medical attention.
  • Severe infections: opportunistic infections due to immunosuppression.
  • Hepatotoxicity: significant liver injury manifesting as jaundice or hepatitis.

Precautions & Warnings

Before initiating therapy, several safety considerations should be addressed.

  • Blood count monitoring: perform baseline and periodic CBC to detect leukopenia.
  • Liver function monitoring: assess hepatic enzymes regularly for signs of toxicity.
  • Pregnancy risk: avoid use in pregnancy (Category D) unless benefits outweigh risks.
  • Dose adjustment: consider renal or hepatic impairment when determining dose.
  • Infection vigilance: educate patients to report fever or signs of infection promptly.
  • Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Azathioprine interacts with several medicines that can alter its efficacy or safety profile.

Major Interactions (Avoid)

  • Allopurinol: may increase azathioprine toxicity by inhibiting its metabolism.
  • Warfarin: can enhance anticoagulant effect, raising bleeding risk.
  • Live vaccines: immunosuppression may lead to uncontrolled infection from the vaccine strain.

Moderate Interactions (Monitor Closely)

  • NSAIDs: may increase risk of bone marrow suppression.
  • ACE inhibitors: potential additive effect on renal function.
  • Sulfonamides and azole antifungals: may interfere with azathioprine metabolism, requiring dose adjustments.

Frequently Asked Questions

Imuran Mitis contains azathioprine, which is prescribed to prevent organ transplant rejection, manage rheumatoid arthritis, control inflammatory bowel disease such as Crohn’s disease and ulcerative colitis, and treat systemic lupus erythematosus by suppressing excessive immune activity.

Azathioprine is converted to 6‑mercaptopurine inside cells, where it blocks purine synthesis. This limits DNA replication in rapidly dividing lymphocytes, reducing their proliferation and dampening the immune response that drives inflammation and graft rejection.

The appropriate dose of Imuran Mitis is individualized by the prescribing clinician based on the specific indication, patient weight, renal and hepatic function, and laboratory monitoring results. Patients should follow the exact regimen provided by their healthcare professional.

Azathioprine is classified as Pregnancy Category D, indicating evidence of risk to the fetus. It should generally be avoided during pregnancy unless the potential benefit justifies the risk. Limited data exist for breastfeeding; the decision should be made with a physician’s guidance.

To request Imuran Mitis, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Both azathioprine and mycophenolate mofetil are antimetabolite immunosuppressants, but they inhibit different enzymes in the purine pathway. Azathioprine is often used where mycophenolate is contraindicated or not tolerated, and each drug has a distinct side‑effect profile and monitoring requirements.

Imuran Mitis should be stored at temperatures below 25 °C, in its original container, protected from moisture and direct sunlight. Keeping the tablet in a dry, cool place helps maintain its potency throughout its shelf life.

Imuran Mitis is taken orally, usually with food or a glass of water to reduce gastrointestinal irritation. The exact dosing schedule—once daily, twice daily, or as otherwise directed—must follow the prescribing clinician’s instructions.

Serious risks include bone marrow aplasia leading to severe pancytopenia, life‑threatening infections due to immunosuppression, hepatotoxicity that can progress to liver failure, and an increased long‑term risk of certain malignancies. Prompt reporting of symptoms such as fever, unexplained bruising or jaundice is essential.

Imuran Mitis is contraindicated in patients with known hypersensitivity to azathioprine or its metabolites, those with active severe infections, pregnant women unless absolutely necessary, and individuals with severe hepatic or bone‑marrow impairment. A thorough medical assessment is required before initiation.
