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.
How it works

Imodium (Loperamide) is an antidiarrheal medicine. It's actually an opioid related to morphine, though it doesn't affect the brain like opioid pain medicines do. Instead, it works directly on muscles in your large intestine to stop contractions and increase the time it takes for stool to move through. The result is less diarrhea and more formed stool.
