The price you pay for Xyrem can vary. Your cost may depend on your treatment plan, your insurance coverage (if you have it), and the pharmacy you use.

To find out how much you’ll pay for Xyrem, talk with your doctor, pharmacist, or insurance provider.

Note: If you have insurance, you may need to get prior authorization before your insurance provider will cover Xyrem. This means your insurer and your doctor will discuss Xyrem in regard to your treatment. Then the insurance company will determine whether the drug is covered. If Xyrem requires prior authorization and you don’t receive it before you start treatment, you could pay the full cost of the drug.

Be sure to ask your insurance company whether Xyrem requires prior authorization.

Below are answers to some frequently asked questions about Xyrem and cost.

How does the cost of Xyrem compare with other similar drugs, such as Xywav?

The cost of Xyrem compared with other drugs, such as Xywav, depends on several factors. These include:

  • whether you have insurance or are paying out of pocket
  • if you qualify for any savings programs
  • the specialty pharmacy you use
  • your health insurance plan (if you have one)

To find out if there’s a cost difference between Xyrem and Xywav, talk with your doctor, pharmacist, or insurance provider. They can determine what your cost will be for each of these drugs.

Is there a patient assistance program available for Xyrem?

Yes. The manufacturer of Xyrem (Jazz Pharmaceuticals) has a program called the Xyrem Patient Assistance Program. If you cannot afford the cost of Xyrem and meet certain eligibility requirements, the program helps pay for the medication.

If you have questions about whether you qualify for any savings programs, you can also talk with your doctor.

Xyrem only comes as a brand-name drug. It’s not currently available 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 is there such a cost difference between brand-name drugs and generics?

Years of research and testing are needed to ensure that brand-name drugs are safe and effective. This testing can make the drugs expensive. The drugmaker of a brand-name drug can sell the drug for up to 20 years. After that, other drugmakers can create generic versions. This competition in the market can lead to lower costs for generics. And because generics have the same active ingredients as brand-name drugs, they don’t need to be studied again. This can also lead to lower generic costs.

If you take Xyrem long term, you may be able to lower your costs in certain situations. Xyrem is only available through a certified specialty pharmacy. Check with your insurance provider or the specialty pharmacy if you can get Xyrem in the following ways:
