Been taking 150mg azathioprine for 15 years. excellent control of u colitis. sister had n-hodgkin's lymphoma. i am 65. should i stop azathioprine now?

See your G.I. doc.: it is good that azathioprine has been able to help you achieve a long-term remission for your ulcerative colitis. A decision to stop it will depend on the appearance of your colitis and other health conditions, including a consideration of your family history, and the possibility of a recurrence after stopping it. I would refer you back to your gastroenterologist for this discussion. Good luck.
