Imodium (Loperamide)

Over-the-counter
Treats diarrhea.

One day is too many days to have diarrhea. Having Imodium (Loperamide) on hand to relieve your symptoms can be a life-saver.

5.8/ 7 average rating with 285 reviewsforImodium
Relieves heartburn and indigestion.

Maalox (aluminum / magnesium / simethicone) gives quick relief for heartburn, gas, and bloating, but it may not be as effective or last as long as other antacids.

Upsides
  • Most people who take Imodium feel there's no hassle and it's definitely worth it!
  • Non-habit forming and available over-the-counter.
  • It comes in caplets, liquid, and chewable tablets so you can use it anywhere you need it.
  • Imodium is used for short-term, chronic and traveler's diarrhea. It's also used for people who have diarrhea caused by cancer or certain medicines that treat cancer.
  • Works quickly.
  • Inexpensive and available over-the-counter.
  • Is one of the first choice medications for heartburn relief if you are pregnant.
Downsides
  • Imodium only treats your diarrhea symptoms. Diarrhea may be caused by a number of conditions and will need specific treatment that deals with the underlying issue.
  • Studies in people taking Imodium for chronic diarrhea showed if the maximum number of doses didn't relieve symptoms in 10 days, then it probably won't work for that condition. You can talk to your doctor about other treatment options.
  • Doesn't last very long. Talk to your doctor or pharmacist if you need longer lasting relief.
  • Is not a good option if you have frequent symptoms (more than 2 times a week). Talk to your doctor or pharmacist about stronger medications.
