About MyNarcolepsyTeam

Xywav is a prescription medication approved by the U.S. Food and Drug Administration (FDA) to treat cataplexy or excessive daytime sleepiness (EDS) in adults and children over 7 years of age with narcolepsy. Xywav is also referred to as calcium, magnesium, potassium, and sodium oxybates.

Xywav is a central nervous system (CNS) depressant, a drug that slows the functions of the CNS. Sodium oxybate (gamma hydroxybutyrate or GHB), one of the main ingredients of Xywav, is naturally produced by the body as an intermediate of the neurotransmitter GABA — which is involved in sleep regulation. Xywav is believed to work by mediating the actions of a GABAB protein receptor at specific neurons during sleep.

Xywav is a Schedule III controlled substance. Because GHB is abused recreationally by some people, Xywav is only available through a restricted program under the FDA’s Risk Evaluation and Mitigation Strategy called Xywav™ and Xyrem® REMS.

How do I take it?
Xywav is a clear oral solution taken twice a night, once before bed and again a few hours later.
