Got an upset stomach and need to stop the runs? Loperamide is the over‑the‑counter drug that slows down your gut so you can get back to feeling normal. It’s the active ingredient in popular brands like Imodium, and doctors often recommend it for short‑term diarrhea relief.
Even though it’s widely available, using loperamide correctly matters. The right dose can ease symptoms in a few hours, but the wrong dose can cause constipation, abdominal pain, or even more serious issues.

Taking more than the recommended amount won’t speed up relief; it only raises the risk of constipation and rare heart rhythm problems.
Most users only feel a bit of constipation if they take a little too much. Other possible reactions include:
