Boxed warning

SERIOUS AND LIFE-THREATENING RISKS FROM USE OF NALBUPHINE HYDROCHLORIDE INJECTION ‎.

Addiction, Abuse, and Misuse Because the use of Nalbuphine Hydrochloride Injection exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death, assess each patient's risk prior to prescribing and reassess all patients regularly for the development of these behaviors and conditions [see WARNINGS ]. Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression may occur with use of Nalbuphine Hydrochloride Injection, especially during initiation or following a dosage increase. To reduce the ‎risk of respiratory depression, proper dosing, and titration of ‎‎Nalbuphine Hydrochloride Injection are essential [see WARNINGS ]. 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 Nalbuphine Hydrochloride Injection and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate [see WARNINGS , PRECAUTIONS; Drug Interactions ].
