Dicyclomine for IBS

Dicyclomine is used for treating symptoms of irritable bowel syndrome (abdominal pain, accompanied by diarrhea and constipation associated with stress.) It works by blocking a chemical in the smooth muscle of the stomach and intestines, causing them to relax, which helps reduce cramping.
