What the FDA labels say
From the Flibanserin (ADDYI) label · effective 2025-12-22
Exacerbated by other CNS depressants, and in settings where flibanserin concentrations are increased.
The risk of CNS depression is increased if ADDYI is taken during waking hours, or if ADDYI is taken with alcohol or other CNS depressants, or with medications that increase flibanserin concentrations, such as CYP3A4 inhibitors [see Contraindications (4), Warnings and Precautions (5.1, 5.2), Adverse Reactions (6.1) , and Drug Interactions (7) ].
Other CNS Depressants Examples Diphenhydramine, opioids, hypnotics, benzodiazepines Clinical Implications The concomitant use of ADDYI with CNS depressants may increase the risk of CNS depression (e.g., somnolence) compared to the use of ADDYI alone.
Preventing or Managing DI Discuss the concomitant use of other CNS depressants with the patient when prescribing ADDYI.
From the Lemborexant (DAYVIGO) label · effective 2025-02-24
Risk increases with dose and use 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.
Complex sleep behaviors may occur following the first or any subsequent use of DAYVIGO, with or without the concomitant use of alcohol and other CNS depressants [see Drug Interactions ( 7.1 )] .
