Boxed Warning
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].
Indications and Usage
Nalbuphine hydrochloride injection is indicated for the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. Nalbuphine hydrochloride injection can also be used as a supplement to balanced anesthesia, for preoperative and postoperative analgesia, and for obstetrical analgesia during labor and delivery. Limitations of Use: Because of the risks of addiction, abuse, and misuse, with opioids, which can occur at any dosage or duration [see WARNINGS], reserve nalbuphine hydrochloride injection for use in patients for whom alternative treatment options [e.g., non-opioid analgesics]: Have not been tolerated, or are not expected to be tolerated, Have not provided adequate analgesia or are not expected to provide adequate analgesia. Nalbuphine hydrochloride injection should not be used for an extended period of time unless the pain remains severe enough to require an opioid analgesic and for which alternative treatment options continue to be inadequate.
Dosage and Administration
Important Dosage and Administration Instructions Nalbuphine hydrochloride injection should be administered as a supplement to general anesthesia only by persons specifically trained in the use of intravenous anesthetics and management of the respiratory effects of potent opioids. Naloxone, resuscitative and intubation equipment and oxygen should be readily available. Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals [see WARNINGS]. Because the risk of overdose increases as opioid doses increase, reserve titration to higher doses of nalbuphine hydrochloride injection for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks. There is variability in the opioid analgesic dose and duration needed to adequately manage pain due both to the cause of pain and to individual patient factors. Initiate the dosing regimen for each patient individually, taking into account the patient’s underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse [see WARNINGS]. Respiratory depression can occur at any time during opioid therapy, especially when initiating and following dosage increases with nalbuphine hydrochloride injection. Consider this risk when selecting an initial dose and when making dose adjustments [see WARNINGS]. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Initial Dosage The usual recommended adult dose is 10 mg for a 70 kg individual administered subcutaneously, intramuscularly, or intravenously; this dose may be repeated every 3 to 6 hours as necessary. Use the lowest dose necessary to achieve adequate analgesia. Dosage should be adjusted according to the severity of the pain, physical status of the patient, and other
Contraindications
Nalbuphine hydrochloride injection is contraindicated in patients with: Significant respiratory depression [see WARNINGS] Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment [see WARNINGS] Known or suspected gastrointestinal obstruction, including paralytic ileus [see WARNINGS] Hypersensitivity to nalbuphine to any of the other ingredients in nalbuphine hydrochloride injection.
Adverse Reactions
The most frequent adverse reaction in 1066 patients treated in clinical studies with nalbuphine hydrochloride injection was sedation 381 (36%). Less frequent reactions were: sweaty/clammy 99 (9%), nausea/vomiting 68 (6%), dizziness/vertigo 58 (5%), dry mouth 44 (4%), and headache 27 (3%). Other adverse reactions which occurred (reported incidence of 1% or less) were: CNS Effects: Nervousness, depression, restlessness, crying, euphoria, floating, hostility, unusual dreams, confusion, faintness, hallucinations, dysphoria, feeling of heaviness, numbness, tingling, unreality. The incidence of psychotomimetic effects, such as unreality, depersonalization, delusions, dysphoria and hallucinations has been shown to be less than that which occurs with pentazocine. Cardiovascular: Hypertension, hypotension, bradycardia, tachycardia. Gastrointestinal: Cramps, dyspepsia, bitter taste. Respiratory: Depression, dyspnea, asthma. Dermatologic: Itching, burning, urticaria. Miscellaneous: Speech difficulty, urinary urgency, blurred vision, flushing and warmth. Allergic Reactions: Anaphylactic/anaphylactoid and other serious hypersensitivity reactions have been reported following the use of nalbuphine and may require immediate, supportive medical treatment. These reactions may include shock, respiratory distress, respiratory arrest, bradycardia, cardiac arrest, hypotension, or laryngeal edema. Some of these allergic reactions may be life-threatening. Other allergic- type reactions reported include stridor, bronchospasm, wheezing, edema, rash, pruritus, nausea, vomiting, diaphoresis, weakness, and shakiness.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably
Overdosage
Clinical Presentation Acute overdose with nalbuphine hydrochloride injection alone can be manifested by respiratory depression and dysphoria. Acute overdose with nalbuphine hydrochloride injection and other opioids or CNS depressants can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, hypoglycemia, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations (see CLINICAL PHARMACOLOGY). Treatment of Overdose In case of overdose, priorities are the reestablishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support measures. Opioid antagonists, such as naloxone, are specific antidotes to respiratory depression resulting from opioid overdose. For clinically significant respiratory or circulatory depression secondary to nalbuphine hydrochloride overdose, administer an opioid antagonist. Because the duration of opioid reversal is expected to be less than the duration of action of nalbuphine, carefully monitor the patient until spontaneous respiration is reliably re-established. If the response to an opioid antagonist is suboptimal or only brief in nature, administer additional antagonist as directed by the product’s prescribing information. In an individual physically dependent on opioids, administration of the recommended usual dosage of the antagonist will precipitate an acute withdrawal syndrome. The severity of the withdrawal symptoms experienced will depend on the degree of physical dependence and the dose of the antagonist administered. If a decision is made t
