Common questions about Xifaxan’s cost

Here are some common questions and answers about Xifaxan.

Why is Xifaxan more expensive than its generic version?

Xifaxan is a brand-name drug. Its generic version is rifaximin. Brand-name drugs can be expensive because of the studies needed to test how safe and effective they are.

Makers of a brand-name drug can patent and sell their drug for up to 20 years. When the patent for a brand-name drug expires, other drugmakers can make and sell generic versions.

This competition may help keep costs of generic medications lower. Also, generic medications contain the same active ingredients as brand-name medications. So they don’t require the same testing, which can be costly.

If you’d like to know more about the cost differences between brand-name and generic drugs, talk with your doctor or pharmacist.

Will the price of Xifaxan with insurance be lower than the price without insurance?

The price of prescription drugs is usually lower with insurance. But you’ll probably have to pay more for Xifaxan because it’s a brand-name drug.

Whether you have health insurance or not, you can check for prescription drug coupons that could help lower the price of Xifaxan. See the “Coupons for Xifaxan” section for more details.

How much will Xifaxan cost if I have Medicare?

How much Xifaxan costs will depend on the type of Medicare plan you have and whether your drug plan covers Xifaxan. Each Medicare plan has its own list of drugs that it covers. This list is called a formulary, which places the drugs on tiers (levels) that determine your cost.

If your Medicare plan covers Xifaxan, it will be placed on a higher tier because it’s a brand-name drug. This means you’ll have a higher copay, or you’ll pay a greater percentage (amount) of the total cost of Xifaxan.

If your Medicare plan doesn’t cover Xifaxan, you’ll likely have to pay the full cost. To save money, you could ask your doctor to prescribe the generic version, rifaximin.

To find out what Xifaxan will cost under your Medicare plan, talk with your plan provider, doctor, or pharmacist.
