What is calcium, magnesium, potassium, and sodium oxybates (Xywav)?

Xywav is a central nervous system depressant. It is used to treat cataplexy (sudden loss of muscle strength) or to reduce daytime sleepiness caused by narcolepsy. For these conditions, Xywav is for use in adults and children at least 7 years old.

Xywav is also used in adults to reduce daytime sleepiness caused by idiopathic hypersomnia (an uncommon chronic sleep disorder that causes daytime sleepiness even after a good night's sleep).

Xywav contains GHB, a known street drug of abuse. Because of the potential for abuse and serious side effects, Xywav is available only from a certified pharmacy under a special program. You must be registered in the program and understand the risks and benefits of calcium, magnesium, potassium, and sodium oxybates.

Xywav may also be used for purposes not listed in this medication guide.
