Sodium Oxybate Oral Solution carries a boxed warning for central nervous system (CNS) depression and abuse and misuse. Taking Sodium Oxybate with other Central Nervous System (CNS) depressants has been associated with trouble breathing (respiratory depression), low blood pressure (hypotension), changes in alertness (drowsiness), fainting (syncope), and death.

Sodium Oxybate is a form of gamma hydroxybutyrate (GHB). Abuse or misuse of illegal GHB alone or with other CNS depressants (drugs that cause changes in alertness or consciousness) may result in seizures, trouble breathing (respiratory depression), changes in alertness (drowsiness), coma, and death. Patients on Sodium Oxybate should be monitored for confusion, anxiety, and suicidality.

Because of these risks, Sodium Oxybate is available only through the XYWAV and XYREM REMS. Patients must be enrolled in the XYWAV and XYREM REMS to receive Sodium Oxybate Oral Solution.
