Azathioprine, sold under the brand name Imuran, among others, is an immunosuppressive medication.[5] It is used for the treatment of rheumatoid arthritis, granulomatosis with polyangiitis, Crohn's disease, ulcerative colitis, and systemic lupus erythematosus; and in kidney transplants to prevent rejection. It is listed by the International Agency for Research on Cancer as a group 1 human carcinogen.[5][6][7][8] It is taken by mouth or injected into a vein.[5]

Common side effects include bone-marrow suppression and vomiting.[5] Bone-marrow suppression is especially common in people with a genetic deficiency of the enzyme thiopurine S-methyltransferase.[5] Other serious risk factors include an increased risk of certain cancers.[5] Use during pregnancy may result in harm to the baby.[5] Azathioprine belongs to the purine analogues subclass of antimetabolites family of medications.[5][9] It works via 6-thioguanine to disrupt the making of RNA and DNA by cells.[5][9]

Azathioprine was first made in 1957.[9] It is on the World Health Organization's List of Essential Medicines.[10] In 2018, it was the 358th most commonly prescribed medication in the United States, with more than 800,000 prescriptions.[11]
