What drugs are used to treat ibs?

IBS: For mild........Low fat, high fiber diet. Medications are laxatives such as metamucil. For moderate........Laxatives such as chronulac or sorbitol, imodium, (loperamide) questran, levsin, bentyl. For severe..............Antidepressants for constant pain.

I prefer None: I have never prescribed drugs for so called ibs. You have to change some bad habits like eating at regular times daily, same quantities, moderate fiber intake and most important 80-100 ounces of caffeine free/alcohol free fluids. Over time possibly 1-3 months your symptoms will reolve, but you must maintin this regimen of retraining your bowel.
