I'm allergic to Asacol and Lialda. My D went from 10-15 times a day to 20-30 times a day when I was on this. I also had severe joint pain(neck and wrists) and then, vomitting, and then severe abdominal pain. I just can't use any 5 asa's. I also tried Imuran and I'm allergic to that also. My doc said that about
50% of people allergic to 5 asa's are allergic to imuran and 6mp. Luck me. I have severe UC throughout my whole colon. I start remi on July 23rd. Alot of people have success on 5 asa's hopefully you do too.
