Im from the Crohns board and most of us have tried it at some point. It is an anti-inflamatory. Helped me for awhile then stopped. Maybe 6 months or so. I then switched to Pentasa which is released in a different part of the GI tract. I hadnt heard of it being prescribed for IBS but if you are inflammed I guess it could help.
