I was in remission (with a few minor flares until my final refractory flare leading to colectomy) for nearly 24 years with Azulfidine, my husband has been in remission for the most part for about 10 years with Asacol, and my son has been in remission for about 4 years with Colazal.
These are all 5-ASA drugs and first line treatment for UC (due to generally good response and low rate of side effects). Since everyone here either had colectomy or is heading for it, naturally they would have failed medical treatment (unless they had surgery for dysplasia or cancer).
