Loperamide

Imodiumâ„¢

What It's For & How To Take

Loperamide is used, along with other treatment such as fluid and salt replacement, to treat diarrhea. This medication decreases the urgent feeling as well as how often you need to move your bowel.

Loperamide is used to treat sudden attacks of diarrhea (including traveler’s diarrhea) as well as on-going diarrhea that someone with irritable bowel syndrome might have. This medication treats the symptoms of diarrhea, not the cause.

This medication is taken, by mouth, after each loose bowel movement or as directed. Adults, if self-treating with the over-the-counter loperamide, should never use more than four tablets in 24 hours. Read the package and do not take more than is written in the instructions.

If you are prescribed this medication, your doctor may have you take up to 8 tablets in 24 hours.

If your symptoms are not getting better within 48 hours or are getting worse, call your doctor.

If you forget to take a dose, take it as soon as you remember. If it is near the time for your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
