Imodium 2 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions
What Is Imodium 2 mg?
Imodium 2 mg is an over-the-counter and prescription medicine containing loperamide hydrochloride, an antidiarrhoeal medication used to treat acute (short-term) diarrhoea and help manage certain types of chronic diarrhoea under medical supervision.
Loperamide works by slowing the movement of the intestines, allowing more water and electrolytes to be absorbed from the stool. This helps reduce the frequency of bowel movements and makes stools firmer.
Imodium 2 mg is commonly available as:
- Capsules
- Tablets
- Orodispersible (melt-in-the-mouth) tablets (in some countries)
How Imodium Works
During diarrhoea, food and fluids pass through the intestines too quickly, reducing the amount of water absorbed.
Loperamide works by:
- Slowing intestinal muscle contractions.
- Allowing more water and salts to be absorbed.
- Reducing the number of bowel movements.
- Making stools firmer.
- Helping relieve the urgent need to use the toilet.
It treats the symptoms of diarrhoea but does not treat the underlying cause, such as a bacterial or viral infection.
