What the FDA labels say
From the Oxycodone (Oxycodone Hydrochloride) label · effective 2026-04-16
Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death.
Reserve concomitant prescribing of Oxycodone Hydrochloride Oral Solution and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate [see Warnings and Precautions (5.4) , Drug Interactions (7) ].
Cytochrome P450 3A4 Interaction The concomitant use of Oxycodone Hydrochloride Oral Solution with all cytochrome P450 3A4 inhibitors may result in an increase in oxycodone plasma concentrations, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression.
Regularly evaluate patients receiving Oxycodone Hydrochloride Oral Solution and any CYP3A4 inhibitor or inducer [see Warnings and Precautions (5.7) , Drug Interactions (7) , Clinical Pharmacology (12.3) ].
Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death.
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).
