What the FDA labels say
From the Azelastine and fluticasone (AZELASTINE HYDROCHLORIDE AND FLUTICASONE PROPIONATE) label · effective 2025-01-31
• Avoid concurrent use of alcohol or other central nervous system (CNS) depressants with azelastine hydrochloride and fluticasone propionate nasal spray because further decreased alertness and impairment of CNS performance may occur.
Concurrent use of azelastine hydrochloride and fluticasone propionate nasal spray with alcohol or other central nervous system depressants should be avoided because additional reductions in alertness and additional impairment of central nervous system performance may occur [see Drug Interactions ( 7.1 )].
Use of Cytochrome P450 3A4 Inhibitors Ritonavir and other strong cytochrome P450 3A4 (CYP3A4) inhibitors can significantly increase plasma fluticasone propionate exposure, resulting in significantly reduced serum cortisol concentrations [see Drug Interactions ( 7.2 ) and Clinical Pharmacology ( 12.3 )] .
Use caution with the coadministration of azelastine hydrochloride and fluticasone propionate nasal spray and other potent CYP3A4 inhibitors, such as ketoconazole [see Drug Interactions ( 7.2 ) and Clinical Pharmacology ( 12.3 )] .
• Other potent CYP3A4 inhibitors, such as ketoconazole: use caution with coadministration.
From the Perampanel (Fycompa) label · effective 2024-01-05
Patients should be carefully observed for signs of central nervous system (CNS) depression, such as somnolence and sedation, when FYCOMPA is used with other drugs with sedative properties because of potential additive effects.
Alcohol and Other CNS Depressants The concomitant use of FYCOMPA and CNS depressants including alcohol may increase CNS depression.
These effects may also be seen when FYCOMPA is used in combination with other CNS depressants.
Patients should limit activity until they have experience with concomitant use of CNS depressants (e.g., benzodiazepines, narcotics, barbiturates, sedating antihistamines).
