Lychol is a brand name for a medication that contains the active ingredient loperamide. It is primarily used to manage acute and chronic diarrhea by slowing down gut movement, which helps reduce the frequency of bowel movements. Lychol is often available in over-the-counter formulations and is typically used for symptomatic relief. However, it's important to consult a healthcare professional before using it, especially in cases of severe or prolonged diarrhea.
