Irritable bowel syndrome (IBS)
Certain types of bacteria, such as E. coli and Salmonella

The recommended dosage of Imodium for adults is 2-4 mg (one or two capsules) after the first loose stool, then 2 mg (one capsule) after each subsequent loose stool. The maximum daily dose is 16 mg.
For children ages 6-12, the recommended dosage is 1-2 mg after the first loose stool, then 1 mg after each subsequent loose stool. The maximum daily dose is 8 mg.
Imodium may interact with other medications, including:
heart rhythm medications
Do not take Imodium if you are taking any of these medications. Speak to your doctor about all of the medications you are taking before starting Imodium.
Mechanism of Action
Imodium works by slowing down the movement of the intestines. This action reduces the number of bowel movements and makes stool less watery.
Imodium is rapidly absorbed from the gastrointestinal tract. The peak plasma concentration is reached within 1-2 hours. Imodium is widely distributed throughout the body and has a half-life of 8-10 hours. It is metabolized in the liver and eliminated in the urine.
There have been several clinical trials conducted to evaluate the efficacy of Imodium in the treatment of diarrhea. In a study of 535 adults with traveler’s diarrhea, Imodium was found to be effective in reducing the duration and severity of diarrhea.
In a study of children with acute infectious diarrhea, Imodium was found to be effective in reducing the duration of diarrhea by an average of 1.3 days.
A study of people with IBS found that Imodium significantly reduced the number of bowel movements and improved stool consistency.
Researches suggest that loperamide, the active ingredient in Imodium, may be an effective treatment for chronic idiopathic constipation.
Alternatives to Imodium
There are a number of alternative medications that can be used to treat diarrhea, including:
Bismuth subsalicylate (Pepto-Bismol)
Speak to your doctor about which medication is right for you.
Is Lomotil more effective than Imodium?
There is no definitive answer to this question as both medications are effective in treating diarrhea. Some studies suggest that Lomotil may be more effective than Imodium, while other studies have found no difference in efficacy. Speak to your doctor about which medication is right for you.
