What is loperamide?
Loperamide slows the rhythm of digestion so that the small intestines have more time to absorb fluid and nutrients from the foods you eat.
Loperamide is used to treat diarrhea. Loperamide is also used to reduce the amount of stool in people who have an ileostomy (re-routing of the bowel through a surgical opening in the stomach).
Loperamide may also be used for other purposes not listed in this medication guide.
Do not use this medication if you are allergic to loperamide, or if you have:
- stools that are bloody, black, or tarry; or
- if you have diarrhea that is caused by taking an antibiotic.
Before taking loperamide, tell your doctor if you are allergic to any drugs, or if you have:
- a fever;
- mucus in your stools;
- a history of liver disease; or
- if you are taking an antibiotic.
If you have any of these conditions, you may need a dose adjustment or special tests to safely take loperamide.

Loperamide can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor’s instructions about the type and amount of liquids you should drink.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, call your doctor. Do not use loperamide to stop the diarrhea unless your doctor has told you to.
