Drug Precautions ::


Pregnancy: Category D. Lactation: Excreted in breast milk. Children: Safety and efficacy not established. Carcinogenesis/mutagenesis: Chronic immunosuppression with azathioprine increases risk of neoplasia. Patients with rheumatoid arthritis previously treated with alkylating agents (eg, cyclophosphamide, chlorambucil, melphalan) may have prohibitive risk of neoplasia. GI toxicity: Hypersensitivity reaction with severe nausea and vomiting may occur. Frequency of gastric disturbances can be reduced by giving in divided doses or after meals. Hematologic effects: Severe hematologic toxicities may occur; monitor blood counts. Hepatoxicity: Occurs primarily in allograft recipients. Rare but life-threatening hepatic veno-occlusive disease has occurred in transplant patients; monitor liver function tests. Superinfection: Serious fungal, viral, bacterial and protozoal infections may develop in patients on long-term immunosuppression.


Drug Side Effects ::

 Adverse Reactions

DERM: Rash. GI: Nausea; vomiting. HEMA: Leukopenia; thrombocytopenia; macrocytic anemia; bleeding; selective erythrocyte aplasia. OTHER: Serious infections; neoplasias.

Drug Mode of Action ::  

 Action Suppresses cell-mediated hypersensitivities; alters antibody production and may reduce inflammation.
