What medicines should be taken in i.b.s?

Depends. Depends on what type of IBS you have… Constipation type we have a few different medications, for diarrhea type there are fewer options. Before diagnosing yourself with IBS though, make sure you have colonoscopy and EGD and labs done and an examination as IBS is what we call a diagnosis of exclusion, where we "rule Out" other causes then call it IBS.
