Physicians should carefully evaluate patients for a history of drug abuse and follow such patients closely. The rapid onset of sedation, coupled with the amnestic features of XYREM, particularly when combined with alcohol, has proven to be dangerous for the voluntary and involuntary user (eg, assault victim). Abuse of illicit GHB, either alone or in combination with other CNS depressants, is associated with CNS adverse reactions, including seizure, respiratory depression, decreases in the level of consciousness, coma, and death. The active ingredient of XYREM, sodium oxybate or gamma hydroxybutyrate (GHB), is a Schedule I controlled substance. XYREM is a Schedule III controlled substance. Patients should be queried about CNS depression-related events upon initiation of XYREM therapy and periodically thereafter. Also caution patients against these hazardous activities for at least 6 hours after taking XYREM. In addition, if short-term use of an opioid (eg, post- or perioperative) is required, interruption of treatment with XYREM should be considered.Īfter first initiating treatment and until certain that XYREM does not affect them adversely (eg, impair judgment, thinking, or motor skills), caution patients against hazardous activities requiring complete mental alertness or motor coordination such as operating hazardous machinery, including automobiles or airplanes. If use of these CNS depressants in combination with XYREM is required, dose reduction or discontinuation of one or more CNS depressants (including XYREM) should be considered. The concurrent use of XYREM with other CNS depressants, including but not limited to opioid analgesics, benzodiazepines, sedating antidepressants or antipsychotics, sedating anti-epileptic drugs, general anesthetics, muscle relaxants, and/or illicit CNS depressants, may increase the risk of respiratory depression, hypotension, profound sedation, syncope, and death.
