Price of xifaxan 550 mg?

Xifaxan (rifaximin) is sold only under the brand name, so you won’t find a generic price. In the United States a typical 20‑tablet bottle (each 550 mg) usually retails for about $300–$400 – roughly $15–$20 per capsule.

Prices can swing a lot depending on the pharmacy, any coupons or patient‑assistance programs you qualify for, and whether you’re using insurance. If you’re looking at a different region or a longer course (e.g., 10–12 weeks for IBS‑D), the total cost will climb proportionally.

Tip: Check with your pharmacy or insurer for the most accurate price for your specific prescription. If you’re in the U.S., the manufacturer’s patient‑assistance program often offers a 30‑day supply for free or heavily discounted, which can cut the cost dramatically.
