What is Rifaximin 550 mg used for?
Rifaximin 550 mg is an antibiotic used to treat irritable bowel syndrome with diarrhea (IBS-D) and hepatic encephalopathy. It works by stopping the growth of certain bacteria in the gut. This helps reduce symptoms like bloating, belly pain, and loose stools. In people with liver disease, it can lower the chance of brain problems caused by too much ammonia in the blood.
