For Crohn's Disease, Maintenance "I have started the Pentasa. It has given me diarrhea and some stomach cramps when taking it. I have to see if after taking it for a week how it will do with the Crohn's or see about getting off of it. I am also getting cramps in the stomach area when taking this medication."

For Inflammatory Bowel Disease "Pro: It kind of worked a bit. My bloodwork improved, and the mildest part of the inflammation went away. Cons: It didn't work enough. The area of more severe inflammation hasn't budged, unfortunately, and I'm still having bad stomach cramps every day. I tried upping my dose from 2 grams to 4 grams, and that actually made my symptoms worse, so I went back down. I'm also losing a lot of hair, but it's not really noticeable to anyone else, and I will say that that's the only side effect I've had from this medication on a 1-2 grams dosage, which I think is pretty good. If your doctor tells you to take this medication, definitely take it! I wish it had worked for me. It does work for a lot of people. I would be happy to take this medication every day for the rest of my life if it only worked!"

For Crohn's Disease, Maintenance "I have had a good experience with Pentasa. I have been on 4g a day for the last 10 years for Crohn's disease. I don't think I have any major side effects. I have been in remission, blood and scope wise, for years. I do have some symptoms, like cramps and upset stomach every now and then, and have to pace myself sometimes, but overall I'm happy with it. It's not completely perfect symptom wise, but I can live a decent life with it, so all good."
