GENERIC NAME: AZATHIOPRINE - ORAL (ay-za-THYE-oh-preen)
BRAND NAME(S): Imuran
WARNING: Long-term use of azathioprine may infrequently increase your risk of developing certain types of cancer (e.g., skin cancer, lymphoma). This risk is higher in people using azathioprine after an organ transplant and in children/young adults being treated for certain bowel diseases (such as Crohn's disease, ulcerative colitis). You must be closely monitored by your doctor during treatment and regularly afterwards if your doctor stops treatment with this medication.
Azathioprine may also cause serious (rarely fatal) blood disorders (decreased bone marrow function leading to anemia, low number of white blood cells and platelets). It can lower your body's ability to fight an infection.
Keep all medical and laboratory appointments. Tell your doctor immediately if you develop any of the following signs: unusual skin changes, change in the appearance/size of moles, unusual growths/lumps, swollen glands, swollen or painful abdomen, unexplained weight loss, night sweats, unexplained itching, signs of infection (e.g., fever, persistent sore throat), easy bruising/bleeding, or unusual tiredness.
