Xifaxan (rifaximin) is an antibiotic that’s used for certain intestinal conditions. The most common uses include treatment of traveler’s diarrhea caused by noninvasive strains of E. coli and prevention of recurrence of hepatic encephalopathy (brain function problems caused by severe liver disease), depending on the indication and country label.
What is Xifaxan used for?
Xifaxan (rifaximin) is marketed as an oral antibiotic for gastrointestinal and liver-related indications. The main labeled uses typically include:
- Traveler’s diarrhea due to noninvasive E. coli [1]
- Hepatic encephalopathy (to help prevent recurrence) in people with liver disease [2]
What is the difference between Xifaxan and rifaximin generics?
Xifaxan is the brand name for rifaximin. Generic rifaximin products usually contain the same active ingredient, rifaximin, but may differ in tablet strength, dosing schedule, excipients, and price. If you’re switching products, it’s best to match the prescribed dose and follow your clinician’s guidance.
How is Xifaxan usually taken?
Dosing depends on the specific condition being treated or prevented. Your prescription label should specify the strength and how many tablets to take and when. If you tell me your dose strength (e.g., 200 mg or 550 mg) and the condition (traveler’s diarrhea vs. hepatic encephalopathy), I can help interpret typical labeling directions.
What side effects do people report with Xifaxan?
Commonly reported side effects for rifaximin brands can include gastrointestinal symptoms such as nausea, abdominal pain, and diarrhea, plus headache. Serious reactions are uncommon, but any new or severe symptoms should be reported to a clinician promptly.
