Generic drug for xifaxan?

Generic name: Rifaximin

Xifaxan® is the brand name for rifaximin. In most countries the same medication is sold under its generic name, rifaximin, without the brand prefix. It contains the exact same active ingredient (rifaximin) and has the same dosage forms (usually 200 mg tablets) and strength, but typically at a lower price.

If you’re looking for a generic alternative, simply ask your pharmacist for “rifaximin.” It’s available in the same doses (e.g., 200 mg tablets for 14‑day courses) and can be used for the same indications:

• Traveler’s diarrhea (after a single 200 mg dose or a 14‑day regimen)
• Irritable bowel syndrome with diarrhea (IBS‑D) – 550 mg twice daily for 2 weeks, then 550 mg once daily for 12 weeks
• Hepatic encephalopathy – 550 mg twice daily

Check with your prescriber or pharmacist for local availability, insurance coverage, and any formulary specifics.
