From the Daridorexant (QUVIVIQ) label · effective 2026-02-26
CNS-Depressant Effects and Daytime Impairment: Impairs alertness and motor coordination including morning impairment.
Risk increases when used with other central nervous system (CNS) depressants.
Co-administration with other CNS depressants (e.g., benzodiazepines, opioids, tricyclic antidepressants, alcohol) increases the risk of CNS depression, which can cause daytime impairment.
Dosage adjustments of QUVIVIQ and of concomitant CNS depressants may be necessary when administered together because of potentially additive effects.
Alcohol and Other CNS Depressants Clinical Implications: Concomitant use of alcohol or other CNS depressants with QUVIVIQ may lead to additive impairment of psychomotor performance and risk of CNS depression [see Clinical Pharmacology (12.2) ] .
