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.

Avoid the use of Promethazine HCl and Codeine Phosphate Oral Solution in patients taking benzodiazepines, other CNS depressants, or alcohol [ see Warnings and Precautions (5.10) , Drug Interactions (7.4) ].

( 5.9 , 7.1 , 7.2 , 7.3 ) 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.

Avoid concurrent use of Promethazine HCl and Codeine Phosphate Oral Solution with alcohol or other central nervous system depressants because additional impairment of central nervous system performance may occur [ see Warnings and Precautions (5.10) ].

Carefully monitor cardiac rhythm when administering SUPRANE to susceptible patients (e.g., patients with congenital Long QT Syndrome or patients taking drugs that can prolong the QT interval).

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.
