Xywav (calcium/magnesium/potassium/sodium oxybates) is a prescription drug that’s used to treat certain sleep disorders. Xywav’s cost may depend on factors such as your dosage and whether you have health insurance.
Xywav is used to treat excessive daytime sleepiness and cataplexy in adults and some children with narcolepsy. It’s also prescribed for adults with idiopathic hypersomnia (excessive daytime sleepiness of unknown cause).
Xywav comes as a liquid solution that you swallow. For more details on Xywav, see this in-depth article.
The price you pay for Xywav can vary. Your cost may depend on your dosage and treatment plan, your insurance coverage (if you have it), and the pharmacy you use.
To find out how much you’ll pay for Xywav, talk with your doctor or insurance provider.
Note: If you have insurance, you may need to get prior authorization before your insurance provider will cover Xywav. This means your insurer and your doctor will discuss Xywav in regard to your treatment. Then the insurance company will determine whether the drug is covered. If Xywav 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 Xywav requires prior authorization.
Xywav only comes as a brand-name drug. It’s not currently available in a generic version. A generic contains an exact copy of the active drug in a brand-name medication but tends to cost less.
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 manufacturer 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.
Xywav is available only through a certified pharmacy. The FDA sometimes requires certified pharmacies for certain drugs to help make sure they’re prescribed safely.
