My doctor had me on it for my ulcer a long time ago however I could not take it anymore because it caused my constipation to be worse. I haven't heard it used for IBS or any other disorder. I know that my doctor had me on it as a short term treatment and didn't know it could be used long term. Did you doctor prescribe it to you to use short term or as a regular maintenance med?
