Has anyone experience with side effects on imuran (azathioprine)?

Side Effects: The typical side effects i tell my patients about include: 1. Leukopenia (low white blood cell count) 2. Transaminitis (increased liver function test levels) 3. Nausea/vomiting 4. Fatigue the drug can be reduced in terms of its dosage to prevent or decrease some side effects.

Bone marrow toxicity: Imuran (azathioprine) is a non specific immunosuppressive drug that works by blocking the proliferation of activated immune white blood cells (lymphocytes, monocytes, granulocytes, etc.). It can cause too much bone marrow suppression, liver toxicity, hair loss, nausea, vomiting, etc. You should discuss any side effects with your doctor.
