Xyrem (sodium oxybate) is a central nervous system depressant. It is used to treat cataplexy (sudden loss of muscle strength) and reduce daytime sleepiness in patients with narcolepsy.

Xyrem is also known as GHB, a known street drug of abuse. Because of the potential for abuse and the serious side effects that may occur, Xyrem is available only from a certified pharmacy under a special program called Xyrem REMS Program. Your doctor must be registered in the program in order to prescribe this medicine for you.
