The onset of action occurs within 2 to 3 minutes after intravenous administration, and in less than 15 minutes following subcutaneous or intramuscular injection. The plasma half-life of nalbuphine is approximately 5 hours.

Side Effects

Like other opioids, Nalbuphine Hydrochloride can cause a number of side effects, including nausea, vomiting, dizziness, and sedation. In rare cases, it can cause serious side effects such as respiratory depression and dependence.

Contraindications

Nalbuphine Hydrochloride is contraindicated in patients who are hypersensitive to nalbuphine or to any of the other ingredients in the formulation. It should also be used with caution in patients with impaired respiratory function or with a history of substance abuse.
