Loperamide is a medication commonly used to treat diarrhea. It works by slowing down the movement in the gut, which decreases the number of bowel movements and makes the stool less watery. Loperamide is available over-the-counter and is often found in products like Imodium. While generally safe for short-term use, it is important to follow the recommended dosage. Overuse can lead to serious side effects, including constipation and abdominal pain. Loperamide should not be used for diarrhea caused by certain infections or conditions, so consulting a healthcare professional is advisable if symptoms persist.
