Xifaxan generically known as rifaximin is an antibiotic medication that is used to treat traveler's diarrhea caused by E. coli bacteria, irritable bowel syndrome with diarrhea (IBS-D), and hepatic encephalopathy (HE). Xifaxan contains an active ingriedents called rifaximin. Rifaximin is a rifamycin antibiotic. It works by inhibiting bacterial RNA synthesis, stopping the growth, and spread of bacteria in the body.
