, toleranceDrug-drug:
Use with benzodiazepines or other CNS depressants, including other opioids, nonbenzodiazepine sedative/hypnotics, anxiolytics, general anesthetics, muscle relaxants, antipsychotics, and alcohol, may cause profound sedation, respiratory depression, coma, and death; reserve concurrent use for when alternative treatment options are inadequate.

Supplement to Balanced Anesthesia
Assess BP, HR, and respiratory rate before and periodically during administration. If respiratory rate is <10/min, assess level of sedation. Physical stimulation may be sufficient to prevent significant hypoventilation. Dose may need to be ↓ by 2550%. Monitor for respiratory depression, especially during initiation or following dose ↑; serious, life-threatening, or fatal respiratory depression may occur. May cause sleep-related breathing disorders (central sleep apnea, sleep-related hypoxemia). Nalbuphine produces respiratory depression, but this does not markedly ↑ with increased doses.
Assess risk for opioid addiction, abuse, or misuse prior to administration.
