• 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.

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 Fentanyl Citrate Injection and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate [see Warnings and Precautions (5.3) , Drug Interactions (7) ] .

Adequate facilities should be available for postoperative monitoring and ventilation of patients administered anesthetic doses of Fentanyl Citrate Injection.

Risks from Concomitant Use with Benzodiazepines or Other Central Nervous System Depressants When benzodiazepines or other CNS depressants are used with Fentanyl Citrate Injection, pulmonary arterial pressure may be decreased.

Benzodiazepines and Opioids (MAC Reduction) Benzodiazepines and opioids decrease the amount of desflurane (MAC) needed to produce anesthesia.

Neuromuscular Blocking Agents Anesthetic concentrations of desflurane at equilibrium (administered for 15 or more minutes before testing) reduced the ED 95 of succinylcholine by approximately 30% and that of atracurium and pancuronium by approximately 50% compared to N 2 O/opioid anesthesia (see Table 4).

During maintenance of anesthesia, the dose of nondepolarizing muscle relaxants is likely to be reduced compared to that during N2O/opioid anesthesia.

• Concomitant use of N 2 O, benzodiazepines and/or opioids reduces the MAC of SUPRANE.

This effect is shown in Table 3 for intravenous midazolam (25-50 µg/kg) and intravenous fentanyl (3-6 µg/kg) in patients of two different age groups.
