Stephen: I am a strong believer on staying on some sort of maintenance med. (although you will find differing opinions). I have been lucky since my 1990 resection to have limited care compared to what others have had. I believe that the Pentasa I take helps---maybe not dramatically and not when I really flare, but it keeps me more stable. I know because I experimented with "med holidays" where I would abandon the pentasa for a while. I noticed a big difference. Pentasa and Asacol work in differnt parts of the body. I would discuss this with your doc....glad you are going in!
