Azathioprine and mercaptopurine work to keep people who have Crohn's disease in remission. They are also used to allow the person to stop using corticosteroids.1
Mercaptopurine may be able to prevent Crohn's disease from coming back after surgery. It can at least lengthen the amount of time without disease after surgery. It's likely that azathioprine works as well.1
Both azathioprine and mercaptopurine can treat and heal fistulas.1
Methotrexate works to stop symptoms of active Crohn's disease and to put the disease in remission. It can keep Crohn's disease in remission when taken long term. It is also used to help people who have Crohn's disease stop taking corticosteroids.1
Azathioprine and mercaptopurine work to stop active symptoms of ulcerative colitis. They can also be used to help people who have ulcerative colitis stop taking corticosteroids.1

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Women who use this medicine during pregnancy have a slightly higher chance of having a baby with birth defects. If you are pregnant or planning to get pregnant, you and your doctor must weigh the risks of using this medicine against the risks of not treating your condition.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
