What’s the generic version of Xifaxan (rifaximin) likely to cost?
Xifaxan is brand rifaximin. Generic rifaximin pricing varies a lot by dose, formulation (tablet vs. pill strength), quantity (e.g., 42 vs. 60 vs. 120 tablets), and whether you’re buying retail cash price or using insurance.
If you’re comparing “generic Xifaxan” pricing, the most useful approach is to check current offer prices for the exact strength and count you need, because rifaximin is typically priced and billed by strength/pack size.
Is “generic Xifaxan” the same as rifaximin from other manufacturers?
Yes. A generic version is typically approved as rifaximin with the same active ingredient (rifaximin) as Xifaxan, though excipients and appearance can differ. Price differences come mainly from manufacturer, pharmacy, and contract pricing rather than a different drug.
How can I estimate the generic Xifaxan cost you’ll actually pay?
Your out-of-pocket cost usually depends on which of these applies:
- Retail cash price at the pharmacy
- Insurance copay/coinsurance (often lower than cash)
- Pharmacy discount programs (sometimes near cash price, sometimes meaningfully less)
- Whether the prescription is written as “rifaximin” (generic) versus “Xifaxan” (brand), and whether substitution is allowed
To estimate accurately, match the pharmacy listing to the exact regimen your prescription specifies (strength and number of tablets).

If you tell me your prescription details, I can narrow the estimate
Generic Xifaxan cost swings most based on dose and package size. If you share:
1) the strength (e.g., 200 mg tablets or 550 mg tablets),
2) how many tablets per day,
3) your pharmacy (or ZIP code),
4) whether you want cash price or insured price,
I can help you pinpoint what price range is realistic for that specific generic.
Important patient cost note (insurance or prior authorization)
For rifaximin, insurers sometimes require prior authorization or limit coverage to specific indications. If coverage is denied, your cost can jump to cash pricing even if a generic exists.
