SODIUM OXYBATE

Standard Dose

2 DOSAGE AND ADMINISTRATION Dosing for Adults: • Initiate dosage at 4.5 g once per night orally ( 2.1 ). • Titrate to effect in increments of 1.5 g per night at weekly intervals ( 2.1 ). • Recommended dosage range: 6 g to 9 g once per night orally ( 2.1 ). Dosing for Pediatric Patients (7 Years of Age and Older): • The recommended starting dosage, titration regimen, and maximum total nightly dosage are based on body weight ( 2.2 ) • Pediatric patients 7 years and older weighing at least 45 kg : The recommended starting dosage is 4.5 g once per night. Increase the dosage by 1.5 g per night at weekly intervals to the maximum recommended dosage of 9 g once per night orally. The dosage may be gradually titrated based on efficacy and tolerability ( 2.2 ). • Pediatric patients 7 years and older weighing less than 45 kg : Because the recommended starting dosage cannot be achieved with the available strengths of LUMRYZ, use another sodium oxybate product to initiate treatment ( 2.2 ). Important Administration Information • Prepare the dose of LUMRYZ prior to bedtime; suspend dose in approximately ⅓ cup of water (with or without calorie-free drink mix or flavored water enhancer) in the mixing cup provided ( 2.3 ). • Allow 2 hours after eating before dosing ( 2.3 ). • Take LUMRYZ while in bed and lie down after dosing ( 2.3 ). 2.1 Adult Dosing Information The recommended starting dosage of LUMRYZ in adults is 4.5 grams (g) once per night administered orally. Increase the dosage by 1.5 g per night at weekly intervals to the recommended dosage range of 6 g to 9 g once per night orally. The dosage may be gradually titrated based on efficacy and tolerability. Doses higher than 9 g per night have not been studied and should not ordinarily be administered. 2.2 Pediatric Dosing Information The recommended starting pediatric dosage, titration regimen, and maximum total nightly dosage are based on patient weight. Pediatric Patients 7 years and Older Weighing at least 45 kg The recommended starting dosage of LUMRYZ in pediatric patients 7 years and older weighing at least 45 kg is 4.5 g once per night administered orally. Increase the dosage by 1.5 g per night at weekly intervals to the maximum recommended dosage of 9 g once per night orally. The dosage may be gradually titrated based on efficacy and tolerability. Pediatric Patients 7 years and Older Weighing Less than 45 kg Because the recommended starting dosage in pediatric patients 7 years and older weighing less than 45 kg cannot be achieved with the available strengths of LUMRYZ, use another sodium oxybate product to initiate treatment. Refer to the Prescribing Information of other sodium oxybate products for the recommended dosage for those products. The maximum recommended dosage for patients 7 years and older weighing 20 kg to <30 kg is 6 g once per night orally, and the maximum recommended dosage for patients 7 years and older weighing 30 kg to <45 kg is 7.5 g once per night orally [ see Dosage and Administration ( 2.4 ) ]. There is insufficient information to provide specific dosing recommendations for patients 7 years and older who weigh less than 20 kg. 2.3 Important Administration Instructions LUMRYZ is taken orally as a single dose at bedtime. Prepare the dose of LUMRYZ prior to bedtime. Prior to ingestion, the dose of LUMRYZ should be suspended in approximately 1/3 cup (approximately 80 mL) of water (with or without calorie-free drink mix or flavored water enhancer) in the mixing cup provided [see Instructions for Use ] . Do not use hot water [see Clinical Pharmacology (12.3) ] . After mixing, consume LUMRYZ within 30 minutes. Take LUMRYZ at least 2 hours after eating [see Clinical Pharmacology (12.3) ]. Patients should take LUMRYZ while in bed and lie down immediately after dosing as LUMRYZ may cause them to fall asleep abruptly without first feeling drowsy. Patients will often fall asleep within 5 minutes of taking LUMRYZ, and will usually fall asleep within 15 minutes, though the time it takes any individual patient to fall asleep may vary from night to night. Patients should remain in bed following ingestion of LUMRYZ. 2.4 Switching Patients from Immediate-Release Sodium Oxybate Patients who are currently being treated with immediate-release sodium oxybate may be switched to LUMRYZ at the nearest equivalent dosage in grams per night (e.g., 7.5 g sodium oxybate divided into two 3.75 g doses per night to 7.5 g LUMRYZ once per night).

Boxed Warning

WARNING: CENTRAL NERVOUS SYSTEM (CNS) DEPRESSION AND ABUSE AND MISUSE Central Nervous System Depression LUMRYZ (sodium oxybate) is a CNS depressant. Clinically significant respiratory depression and obtundation may occur in patients treated with LUMRYZ at recommended doses [see Warnings and Precautions (5.1) ] . Many patients who received sodium oxybate during clinical trials in narcolepsy were receiving central nervous system stimulants [see Clinical Trials (14) ] . Abuse and Misuse LUMRYZ (sodium oxybate) is the sodium salt of gamma-hydroxybutyrate (GHB). Abuse or misuse 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 [see Warnings and Precautions (5.2) ] . Because of the risks of CNS depression and abuse and misuse, LUMRYZ is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the LUMRYZ REMS [see Warnings and Precautions (5.3) ]. WARNING: CENTRAL NERVOUS SYSTEM (CNS) DEPRESSION AND ABUSE AND MISUSE See full prescribing information for complete boxed warning. Central Nervous System Depression • LUMRYZ is a CNS depressant, and respiratory depression can occur with LUMRYZ use ( 5.1 , 5.4 ) Abuse and Misuse • LUMRYZ is the sodium salt of gamma-hydroxybutyrate (GHB). Abuse or misuse of illicit GHB is associated with CNS adverse reactions, including seizure, respiratory depression, decreased consciousness, coma, and death ( 5.2 , 9.2 ) LUMRYZ is available only through a restricted program called the LUMRYZ REMS ( 5.3 )

Monitoring

• 5 WARNINGS AND PRECAUTIONS • CNS depression: Use caution when considering the concurrent use of LUMRYZ with other CNS depressants ( 5.1 ).
• • Caution patients against hazardous activities requiring complete mental alertness or motor coordination within the first 6 hours of dosing or after first initiating treatment until certain that LUMRYZ does not affect them adversely ( 5.1 ).
• • Depression and suicidality: Monitor patients for emergent or increased depression and suicidality ( 5.5 ).
• • Confusion/Anxiety: Monitor for impaired motor/cognitive function ( 5.6 ).

Interaction Notes

• 7 DRUG INTERACTIONS 7.1 Alcohol, Sedative Hypnotics, and CNS Depressants LUMRYZ is contraindicated for use in combination with alcohol or sedative hypnotics.
• Use of other CNS depressants may potentiate the CNS-depressant effects of LUMRYZ [see Warnings and Precautions (5.1) ] .
• In addition to coadministration of LUMRYZ and alcohol being contraindicated because of respiratory depression, consumption of alcohol while taking LUMRYZ may also result in a more rapid release of the dose of sodium oxybate [see Clinical Pharmacology (12.3) ] .
