Rifaximin

Rifaximin is a prescription antibiotic used to treat certain bacterial infections in the gut. It works by staying mostly in the intestines and helping stop bacteria from growing, which can reduce infection-related symptoms.

It is commonly used for traveler’s diarrhea caused by certain bacteria, hepatic encephalopathy, and irritable bowel syndrome with diarrhea in some patients. Use it exactly as prescribed, and tell your healthcare provider if you are pregnant, breastfeeding, or have severe liver disease.
