Azathioprine
"Been taking it for 7 months prior to this had really bad flares nothing worked. Steroids wouldn't control. Had UC for 19 years and had spread further up my colon. Was offered azathioprine. So thought why not. Best thing I have ever done, I have my life back.  My regular bloods are all normal. Not taking anything else for UC. Toilet once a day. Have joint pain but that a small price to pay. Don't have to worry about being near a toilet."
