Off Label Uses
Data from three prospective, randomized, double-blind studies and one open-label dose-finding study support the use of nalbuphine in the treatment of opioid-induced pruritus [Charuluxananan 1999], [Charuluxananan 2001], [Charuluxananan 2003], [Cohen 1992]. Clinical experience also suggests the utility of nalbuphine in the treatment of opioid-induced pruritus [Ganesh 2007]. Additional trials may be necessary to further define the role of nalbuphine in this condition.
Hypersensitivity to nalbuphine or any component of the formulation; significant respiratory depression; acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment; GI obstruction, including paralytic ileus (known or suspected).
Documentation of allergenic cross-reactivity for opioids is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Surgical abdomen (eg, acute appendicitis, pancreatitis); mild pain that can be managed with other pain medications; acute alcoholism; delirium tremens; convulsive disorders; severe CNS depression; increased cerebrospinal or intracranial pressure; head injury; concurrent or within 14 days of monoamine oxidase (MAO) inhibitor therapy; pregnancy; breastfeeding.
Pain management: IM, IV, SubQ: 10 mg every 3 to 6 hours as needed (based on a 70 kg patient); may titrate dose to appropriate effect. Maximum dose in nonopioid-tolerant patients: 20 mg/dose; 160 mg/day.
Discontinuation of therapy: When discontinuing chronic opioid therapy, the dose should be gradually tapered down. An optimal universal tapering schedule for all patients has not been established (CDC [Dowell 2016]). Proposed schedules range from slow (eg, 10% reductions per week) to rapid (eg, 25% to 50% reduction every few days) (CDC 2015). Tapering schedules should be individualized to minimize opioid withdrawal while considering patient-specific goals and concerns as well as the pharmacokinetics of the opioid being tapered. An even slower taper may be appropriate in patients who have been receiving opioids for a long duration (eg, years), particularly in the final stage of tapering, whereas more rapid tapers may be appropriate in patients experiencing severe adverse events (CDC [Dowell 2016]). Monitor carefully for signs/symptoms of withdrawal. If the patient displays withdrawal symptoms, consider slowing the taper schedule; alterations may include increasing the interval between dose reductions, decreasing amount of daily dose reduction, pausing the taper and restarting when the patient is ready, and/or coadministration of an alpha-2 agonist (eg, clonidine) to blunt withdrawal symptoms (Berna 2015; CDC [Dowell 2016]). Continue to offer nonopioid analgesics as needed for pain management during the taper; consider nonopioid adjunctive treatments for withdrawal symptoms (eg, GI complaints, muscle spasm) as needed (Berna 2015; Sevarino 2018).
Surgical anesthesia supplement: IV: Induction: 0.3 to 3 mg/kg over 10 to 15 minutes; maintenance: 0.25 to 0.5 mg/kg as required.
Opioid-induced pruritus (off-label use): IV: 2.5 to 5 mg; may repeat dose (Charuluxananan 1999; Charuluxananan 2001; Charuluxananan 2003; Cohen 1992; Ganesh 2007)
Refer to adult dosing. Initiate therapy with reduced doses and use with caution.
Analgesia, moderate to severe: Limited data available: Children and Adolescents: IM, IV, SubQ: 0.1 to 0.2 mg/kg every 3 to 4 hours as needed; higher single doses of 0.3 mg/kg have also been used as a one-time dose perioperatively; maximum single dose: 20 mg/dose; maximum daily dose: 160 mg/day (Bhatt-Mehta 1991; Kliegman 2007)
IM, SubQ: Administer undiluted.
IV: Administer undiluted over at least 2 to 3 minutes; larger induction doses should be administered over 10 to 15 minutes (Nursing 2016)

ALERT: U.S. Boxed WarningLife-threatening respiratory depression:
Serious, life-threatening, or fatal respiratory depression may occur with use of nalbuphine, particularly when used concomitantly with other opioids or CNS depressants. Monitor for respiratory depression, especially during initiation of nalbuphine or following a dose increase.Risks from concomitant use with benzodiazepines or other CNS depressants:
Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of nalbuphine and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.
Concerns related to adverse effects:
• Cardiac effects: Bradycardia has been reported in patients who did not receive atropine preoperatively.
• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).
• Hypotension: May cause severe hypotension (including orthostatic hypotension and syncope); use with caution in patients with hypovolemia, cardiovascular disease (including acute MI), or drugs that may exaggerate hypotensive effects (including phenothiazines or general anesthetics). Monitor for symptoms of hypotension following initiation or dose titration. Avoid use in patients with circulatory shock.
• Respiratory depression: [US Boxed Warning]: Serious, life-threatening, or fatal respiratory depression may occur. Monitor closely for respiratory depression, especially during initiation or dose escalation. Carbon dioxide retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids.
• Abdominal conditions: May obscure diagnosis or clinical course of patients with acute abdominal conditions.
• Adrenocortical insufficiency: Use with caution in patients with adrenal insufficiency, including Addison disease. Long-term opioid use may cause secondary hypogonadism, which may lead to sexual dysfunction, infertility, mood disorders, and osteoporosis (Brennan 2013).
• Biliary tract impairment: Use with caution in patients with biliary tract dysfunction or acute pancreatitis; opioids may cause constriction of sphincter of Oddi.
• Cardiovascular disease: Use with caution in patients with cardiovascular disease, including myocardial infarction patients who have nausea or vomiting.
• CNS depression/coma: Avoid use in patients with impaired consciousness or coma as these patients are susceptible to intracranial effects of CO2 retention.
• Delirium tremens: Use with caution in patients with delirium tremens.
• Head trauma: Use with extreme caution in patients with head injury, intracranial lesions, or elevated intracranial pressure; exaggerated elevation of ICP may occur.
• Hepatic impairment: Use with caution in patients with hepatic impairment; dosage reduction recommended.
• Obesity: Use with caution in patients who are morbidly obese.
• Prostatic hyperplasia/urinary stricture: Use with caution in patients with prostatic hyperplasia and/or urinary stricture.
• Psychosis: Use with caution in patients with toxic psychosis.
• Renal impairment: Use with caution in patients with renal impairment; dosage reduction recommended.
• Respiratory disease: Use with caution and monitor for respiratory depression in patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with a substantially decreased respiratory reserve, hypoxia, hypercapnia, or preexisting respiratory depression, particularly when initiating and titrating therapy; critical respiratory depression may occur, even at therapeutic dosages. Consider the use of alternative nonopioid analgesics in these patients.
• Seizures: Use with caution in patients with a history of seizure disorders; may cause or exacerbate preexisting seizures.
• Sleep-disordered breathing: Use opioids with caution for chronic pain and titrate dosage cautiously in patients with risk factors for sleep-disordered breathing, including HF and obesity. Avoid opioids in patients with moderate to severe sleep-disordered breathing (Dowell [CDC 2016]).
• Thyroid dysfunction: Use with caution in patients with thyroid dysfunction.
Concurrent drug therapy issues:
• Benzodiazepines or other CNS depressants: [US Boxed Warning]: Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of nalbuphine and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosage and durations to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation.
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Cachectic or debilitated patients: Use with caution in cachectic or debilitated patients; there is a greater potential for critical respiratory depression, even at therapeutic dosages. Consider the use of alternative nonopioid analgesics in these patients.
• Elderly: Use with caution in the elderly; may be more sensitive to adverse effects. Clearance may be reduced in older adults (with or without renal impairment), resulting in a narrow therapeutic window and increasing the risk for respiratory depression or overdose (Dowell [CDC 2016]). Consider the use of alternative nonopioid analgesics in these patients.
• Neonates: Neonatal withdrawal syndrome: Prolonged use of opioids during pregnancy can cause neonatal withdrawal syndrome, which may be life-threatening if not recognized and treated according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available. Signs and symptoms include irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea, and failure to gain weight. Onset, duration, and severity depend on the drug used, duration of use, maternal dose, and rate of drug elimination by the newborn.
• Abuse/misuse/diversion: Use with caution in patients with a history of drug abuse or acute alcoholism; potential for drug dependency exists.
• Optimal regimen: An opioid-containing analgesic regimen should be tailored to each patient's needs and based upon the type of pain being treated (acute versus chronic), the route of administration, degree of tolerance for opioids (naive versus chronic user), age, weight, and medical condition. The optimal analgesic dose varies widely among patients; doses should be titrated to pain relief/prevention.
• Surgery: Opioids decrease bowel motility; monitor for decreased bowel motility in postop patients receiving opioids. Use with caution in the perioperative setting; individualize treatment when transitioning from parenteral to oral analgesics.
• Withdrawal: Concurrent use of agonist/antagonist analgesics may precipitate withdrawal symptoms and/or reduced analgesic efficacy in patients following prolonged therapy with mu opioid agonists. Abrupt discontinuation following prolonged use may also lead to withdrawal symptoms.
Relief of pain, respiratory and mental status, blood pressure; bowel function
Nalbuphine crosses the placenta.
Nalbuphine concentrations in cord blood may be similar to or greater than the maternal serum concentrations. Elimination by the newborn may be delayed due to a longer half-life (Nicolle 1996; Wilson 1986).
Opioids used as part of obstetric analgesia/anesthesia during labor and delivery may temporarily affect the fetal heart rate (ACOG 209 2019). Severe bradycardia (which may be prolonged and result in neurologic damage), respiratory depression, apnea, cyanosis, and hypotonia have been reported in the fetus and newborn following exposure during labor. A sinusoidal fetal heart rate pattern has also been reported. Newborns should be monitored closely; naloxone may reverse some of these effects.
If chronic opioid exposure occurs in pregnancy, adverse events in the newborn (including withdrawal) may occur; monitoring of the neonate is recommended. The minimum effective dose should be used if opioids are needed (Chou 2009). Neonatal abstinence syndrome following opioid exposure may present with autonomic (eg, fever, temperature instability), gastrointestinal (eg, diarrhea, vomiting, poor feeding/weight gain), or neurologic (eg, high-pitched crying, increased muscle tone, irritability, seizure, tremor) symptoms (Dow 2012; Hudak 2012).
Nalbuphine is approved for use in obstetrical analgesia during labor and delivery. Nalbuphine has also been evaluated for the management of opioid-induced pruritus following neuraxial analgesia/anesthesia in women who have had cesarean deliveries (ACOG 209 2019; Jannuzzi 2016; Tubog 2019).
Long-term opioid use may cause secondary hypogonadism, which may lead to sexual dysfunction or infertility in men and women (Brennan 2013).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience nausea, vomiting, fatigue, or sweating a lot. Have patient report immediately to prescriber signs of adrenal gland problems (severe nausea, vomiting, severe dizziness, passing out, muscle weakness, severe fatigue, mood changes, lack of appetite, or weight loss), signs of serotonin syndrome (dizziness, severe headache, agitation, hallucinations, tachycardia, arrhythmia, flushing, tremors, sweating a lot, change in balance, severe nausea, or severe diarrhea), severe dizziness, passing out, severe headache, difficulty breathing, slow breathing, shallow breathing, confusion, bradycardia, tachycardia, mood changes, severe anxiety, hallucinations, polyuria, difficulty speaking, or vision changes (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
