Imodium (loperamide) (loperamide) — Uses, Dosage, Side Effects & Safety

Drug class: Antidiarrheal

Overview

Imodium (loperamide) is a medication used to treat sudden (acute) and long-lasting (chronic) diarrhea in adults and children. It works by slowing down the movement of the gut, which helps reduce the frequency and urgency of bowel movements. Loperamide acts on the opioid receptors in the intestinal wall, decreasing peristalsis and increasing the absorption of fluids and electrolytes from the intestines. It does not treat the underlying cause of diarrhea but helps manage symptoms. Key points: Imodium should not be used for diarrhea caused by certain infections or in cases of bloody or high-fever diarrhea. Always follow dosing instructions and consult a healthcare provider if symptoms persist or worsen.
