As with all medications, the cost of Xifaxan can vary. Factors that may affect the price you’ll pay include:

- your insurance coverage
- the pharmacy you use
- whether Xifaxan has a savings program (see the “Financial and insurance assistance” section below)
To find out what the cost of Xifaxan will be for you, talk with your doctor, pharmacist, or insurance provider.
Note: If you have insurance, your insurance company may require prior authorization before it covers Xifaxan. This means the company and your doctor will discuss Xifaxan in regard to your treatment.

If a drug requires prior authorization but you start treatment without the prior approval, you could pay the full cost of the medication. You can ask your insurance company whether Xifaxan requires prior authorization.
Here are answers to some frequently asked questions about drug cost and Xifaxan.

Additionally, Xifaxan’s cost may depend on the condition it’s prescribed to treat. Xifaxan can be used to treat travelers’ diarrhea, irritable bowel syndrome, and a liver condition known as hepatic encephalopathy.

Does Xifaxan 550 mg cost more than Xifaxan 200 mg?
It’s possible. The cost of Xifaxan’s 550-milligram (mg) or 200-mg tablet will depend on your insurance coverage. If you don’t have insurance, it may depend on the pharmacy you use. However, it’s likely that Xifaxan’s 550-mg tablets will cost more than the 200-mg tablets. This is because the 550-mg strength contains more of the active drug than the 200-mg one.
To compare the prices of Xifaxan’s different strengths, talk with your insurance provider or your pharmacist.
Is Xifaxan covered by Medicare?
It’s possible. Whether Medicare covers Xifaxan may depend your prescription drug plan (PDP).
If you have questions about coverage, reach out to your insurance provider.
Xifaxan is only available as a brand-name drug. It doesn’t come in a generic version. A generic drug is an exact copy of the active drug in a brand-name medication.
Generics tend to cost less than brand-name drugs.
WHY ARE COSTS DIFFERENT FOR BRAND-NAME DRUGS VS. GENERIC DRUGS?
Brand-name drugs can be expensive because of the research needed to test their safety and effectiveness. The manufacturer of a brand-name drug can sell it for up to 20 years. When the brand-name drug’s patent expires, multiple manufacturers can create generic versions. This marketplace competition may lead to lower costs for generics. Also, because generics contain the same active ingredients as brand-name drugs, they don’t require the same costly testing.
