What does rifaximin 550 mg cost (and what price should you expect)?
Rifaximin 550 mg pricing depends heavily on whether you mean the brand product (Xifaxan) or a generic, plus your country, pharmacy, and insurance coverage. In the U.S., the most widely used comparison point is the brand’s current list price and what manufacturers set for the NDCs sold by pharmacies.

Is there a generic version of rifaximin 550? Does that lower the price?
Generic rifaximin is typically cheaper than the branded 550 mg product, but the exact savings vary by pharmacy and by which generic NDC is dispensed. If you’re quoted a high price, it can help to ask the pharmacy whether they can substitute a generic (if eligible under your prescription and local rules) and to confirm the exact NDC on the label.
How do insurance and copays change the “out-of-pocket” price?
Even if the “sticker” price is high, many patients pay a much lower amount with:
- Commercial insurance (copay or coinsurance)
- Medicare Part D
- Patient assistance programs (when available and eligible)
Because rifaximin is often prescribed for specific indications, coverage rules can differ by diagnosis and prior authorization requirements. The same prescription can land in a different price tier depending on plan formularies.
What’s the fastest way to get an accurate price near you?
To get a real number quickly, ask your pharmacy for:
- The cash price for the exact strength (550 mg)
- The cash price for generic vs brand
- The price with your insurance and the exact copay amount
- The NDC they plan to dispense
If you share your country (and whether you mean brand Xifaxan or generic) and whether you want cash price or with insurance, I can help you narrow what a typical range looks like and what to ask the pharmacy.
