Pentasa is the only medication I am currently on. I was diagnosed in January and was on pentasa as well as prednisone to stop my flare. I have been off of prednisone for 3 months and am doing fine. I don't have any side effects, but I know some people feel that it does not help them or some people's symptoms get worse. I do have some gas and gas pain, but other than that I am fine. This disease is so individual, as are the medications that will help each person. Are you taking pentasa now?
Good luck to you!
