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.
Strong CYP2C19 Inhibitors Examples Proton pump inhibitors, selective serotonin reuptake inhibitors, benzodiazepines, antifungals Clinical Implications The concomitant use of ADDYI with strong CYP2C19 inhibitors may increase flibanserin exposure which may increase the risk of hypotension, syncope, and CNS depression.
Preventing or Managing DI Discuss the concomitant use of other CNS depressants with the patient when prescribing ADDYI.
