Azasan oral Warnings
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.
Azasan oral Uses
Azathioprine is used with other medications to prevent rejection of a kidney transplant. It works by weakening your body's defense system (immune system) to help your body accept the new kidney as if it were your own. This medication belongs to a class of drugs known as immunosuppressants.
Azathioprine is also used to treat patients with severe rheumatoid arthritis who have not responded to other medications (e.g., nonsteroidal anti-inflammatory drugs/NSAIDs such as ibuprofen). Rheumatoid arthritis is thought to be caused by the immune system attacking the joints. Early treatment of rheumatoid arthritis with more aggressive therapy such as azathioprine helps to reduce further joint damage and to preserve joint function.
Talk to the doctor about the risks and benefits of azathioprine, especially when used in children and young adults.
