Imodium A-D: Uses & Side Effects

Imodium A-D (loperamide) slows the rhythm of digestion so that the small intestines have more time to absorb fluid and nutrients from the foods you eat. It is used to treat diarrhea and to reduce the amount of stool in people who have an ileostomy (re-routing of the bowel through a surgical opening in the stomach).

 

What should you know before taking this medicine?

You should not use Imodium A-D if you are allergic to loperamide, or if you have:
