The FDA has issued a drug safety communication to announce safety-related updates to the prescribing information for immediate-release (IR) and extended-release (ER)/long-acting (LA) opioid analgesics, including updates to Boxed Warnings, Indications and Usage, Dosage and Administration, Warnings and Precautions, and the Medication Guide. These safety labeling changes are intended to provide clarity on appropriate patient populations for opioid treatment, appropriate dosage and administration, and updated information on the risks associated with opioid use. The required safety labeling changes include stating:
the risk of overdose increases as the dosage increases for all opioid pain medicines;
IR opioids should not be used for an extended period of time unless a patient's pain remains severe enough to require them and alternative treatment options continue to be inadequate;
many acute pain conditions treated in the outpatient setting require no more than a few days of an opioid pain medicine;
it is recommended to reserve ER/LA opioid pain medicines for severe and persistent pain that requires an extended treatment period with a daily opioid pain medicine and for which alternative treatment options are inadequate; and
a warning about opioid-induced hyperalgesia (OIH), including information on differentiating OIH symptoms from those of opioid tolerance and withdrawal.

Serious, life-threatening, or fatal respiratory depression may occur with use of nalbuphine, especially during initiation or following a dose increase. To reduce the risk of respiratory depression, proper dosing and titration of nalbuphine are essential.
Concomitant use with benzodiazepines and/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.
Dosage guidance:
Safety: Consider prescribing naloxone for patients with factors associated with an increased risk for overdose, such as history of overdose or substance use disorder, patients with sleep-disordered breathing, higher opioid dosages (≥50 morphine milligram equivalents [MME]/day orally), and/or concomitant benzodiazepine use (Ref).
Opioid-induced pruritus, treatment (off-label use): IV: 2 to 5 mg as a single dose (Ref).
Pain management: Note: Opioids may be part of a comprehensive, multimodal, patient-specific treatment plan for pain. Maximize nonopioid analgesia (when appropriate) prior to initiation of opioid analgesia. Dosing provided is based on typical doses and some patients may require higher or lower doses. Individualize dosing based on patient-specific factors (eg, severity of pain, comorbidities, degree of opioid experience/tolerance) and titrate to patient-specific treatment goals (eg, improvement in function and quality of life, decrease in pain using a validated pain rating scale). Use the lowest effective dose for the shortest period of time (Ref).
IM, IV, SUBQ: 10 mg every 3 to 6 hours as needed (based on a 70 kg patient); adjust dose according to patient response. Maximum dose in opioid-naive patients: 20 mg/dose and up to 160 mg/day.
Discontinuation of therapy: When reducing the dose, discontinuing, or tapering long-term opioid therapy, the dose should be gradually tapered. An optimal tapering schedule has not been established. Individualize tapering based on discussions with patient to minimize withdrawal, while considering patient-specific goals and concerns and the opioid’s pharmacokinetics. Proposed initial schedules range from slow (eg, 10% reduction per week or 10% reduction per month depending on duration of long-term therapy) to rapid (eg, 25% to 50% reduction every few days) (Ref). Slower tapers may be appropriate after long-term use (eg, >1 year), whereas more rapid tapers may be appropriate in patients experiencing severe adverse effects. During tapering, patients may be at an increased risk of overdose if they return to their original (or higher) opioid dose or use illicit opioids, due to rapid loss of tolerance; consider prescribing naloxone. 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 autonomic withdrawal symptoms and other adjunctive agents to treat GI symptoms and muscle spasms, as needed. Continue to offer nonopioid analgesics as needed for pain management during the taper (Ref).
Surgical anesthesia, supplement: IV: Induction: 0.3 to 3 mg/kg over 10 to 15 minutes; maintenance: 0.25 to 0.5 mg/kg; repeat as needed.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
There are no specific dosage adjustments provided in the manufacturer's labeling; however, a reduced dose is recommended. Use with caution.
There are no specific dosage adjustments provided in the manufacturer's labeling; however, a reduced dose is recommended. Use with caution.
Note: Minimize opioid use in older adults unless for the management of severe acute pain. Opioids are associated with an increased risk of falls and inducing or worsening delirium in older adults (Ref).
Refer to adult dosing. Initiate therapy with reduced doses and use with caution.

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 that require mental alertness (eg, operating machinery, driving).
• Hyperalgesia: Opioid-induced hyperalgesia (OIH) has occurred with short-term and prolonged use of opioid analgesics. Symptoms may include increased levels of pain upon opioid dosage increase, decreased levels of pain upon opioid dosage decrease, or pain from ordinarily nonpainful stimuli; symptoms may be suggestive of OIH if there is no evidence of underlying disease progression, opioid tolerance, opioid withdrawal, or addictive behavior. Consider decreasing the current opioid dose or opioid rotation in patients who experience OIH.
• Hypotension: May cause severe hypotension (including orthostatic hypotension and syncope); use with caution in patients with hypovolemia, cardiovascular disease (including acute myocardial infarction [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: Fatal respiratory depression may occur; monitor closely. Carbon dioxide retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. Patients and caregivers should be educated on how to recognize respiratory depression and the importance of getting emergency assistance immediately (eg, calling 911) in the event of known or suspected overdose.
Disease-related concerns:
• 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 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 MI 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.
• Head trauma: Use with extreme caution in patients with brain tumors, head injury, or elevated intracranial pressure (ICP); exaggerated elevation of ICP and respiratory depression may occur.
• Hepatic impairment: Use with caution in patients with hepatic impairment; dosage reduction recommended.
• Mental health conditions: Use opioids with caution for chronic pain in patients with mental health conditions (eg, depression, anxiety disorders, post-traumatic stress disorder) due to potential increased risk for opioid use disorder and overdose; more frequent monitoring is recommended (CDC [Dowell 2022]).
• Prostatic hyperplasia/urinary stricture: Use with caution in patients with prostatic hyperplasia and/or urinary stricture.
• 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-related disorders: Use with caution in patients with sleep-related disorders, including sleep apnea, due to increased risk for respiratory and CNS depression. Monitor carefully and titrate dosage cautiously in patients with mild sleep-disordered breathing. Avoid opioids in patients with moderate to severe sleep-disordered breathing (CDC [Dowell 2022]).
• Thyroid dysfunction: Use with caution in patients with thyroid dysfunction.
Concurrent drug therapy issues:
• Benzodiazepines or other CNS depressants: Consider prescribing naloxone for emergency treatment of opioid overdose in patients taking benzodiazepines or other CNS depressants concomitantly with opioids.
• Monoamine oxidase inhibitors interactions: Concomitant use of nalbuphine with monoamine oxidase inhibitors (MAOIs) can result in coma, severe respiratory depression, cyanosis, and hypotension. Use of nalbuphine with MAOIs or within last 14 days of stopping treatment is not recommended.
Special populations:
• 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.
• Older adults: Use opioids with caution in older adults; may be more sensitive to adverse effects. Clearance may also be reduced in older adults (with or without renal impairment) resulting in a narrow therapeutic window and increased adverse effects. Monitor closely for adverse effects associated with opioid therapy (eg, respiratory and CNS depression, falls, cognitive impairment, constipation) (CDC [Dowell 2022]). Consider the use of alternative nonopioid analgesics in these patients when possible.
• 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.
Other warnings/precautions:
• Abuse/misuse/diversion: Use with caution in patients with a history of substance abuse disorder; potential for drug dependency exists. Other factors associated with increased risk for misuse include concomitant depression or other mental health conditions, higher opioid dosages, or taking other CNS depressants. Consider offering naloxone prescriptions in patients with an increased risk for overdose, such as history of overdose or substance use disorder, higher opioid dosages (≥50 morphine milligram equivalents [MME]/day orally), concomitant benzodiazepine use, and patients at risk for returning to a high dose after losing tolerance (CDC [Dowell 2022]).
• Appropriate use: Outpatient setting: Opioids should not be used as first-line therapy for acute (<1 month duration), subacute (1 to 3 month duration), or chronic pain (>3 month duration [outside of end-of-life or palliative care, active cancer treatment, sickle cell disease, or medication-based opioid use disorder treatment]). Preferred management includes nonpharmacologic therapy and nonopioid therapy (eg, nonsteroidal anti-inflammatory drugs, acetaminophen, certain antiseizure medications, antidepressants) as appropriate for the specific condition. If opioid therapy is initiated, it should be combined with nonpharmacologic and nonopioid therapy, as appropriate. Prior to initiation, known risks and realistic benefits of opioid therapy should be discussed with the patient. Therapy should be initiated at the lowest effective dosage using IR opioids (instead of ER/long-acting opioids). For the treatment of acute pain, therapy should only be given for the expected duration of pain severe enough to require opioids and prescribed as needed (not scheduled). For the treatment of subacute and chronic pain, realistic treatment goals for pain/function should be established, including consideration for discontinuation if benefits do not outweigh risks. Therapy should be continued only if clinically meaningful improvement in pain/function outweighs risks. Risk to patients increases with higher opioid dosages. Dosages ≥50 MME/day are likely to not have increased benefit to pain relief or function relative to overall risk to patients; before increasing dosage to ≥50 MME/day, readdress pain and reassess evidence of individual benefits and risks (CDC [Dowell 2022]).
• Naloxone access: Discuss the availability of naloxone with all patients who are prescribed opioid analgesics, as well as their caregivers, and consider prescribing it to patients who are at increased risk of opioid overdose. These include patients who are also taking benzodiazepines or other CNS depressants, have an opioid use disorder (OUD) (current or history of), or have experienced opioid-induced respiratory depression/opioid overdose. Additionally, health care providers should consider prescribing naloxone to patients prescribed medications to treat OUD; patients at risk of opioid overdose even if they are not taking an opioid analgesic or medication to treat OUD; and patients taking opioids, including methadone or buprenorphine for OUD, if they have household members, including children, or other close contacts at risk for accidental ingestion or opioid overdose. Inform patients and caregivers on options for obtaining naloxone (eg, by prescription, directly from a pharmacist, a community-based program) as permitted by state dispensing and prescribing guidelines. Educate patients and caregivers on how to recognize respiratory depression, proper administration of naloxone, and getting emergency help (FDA 2020).
• 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 postoperative 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.

Chronic opioid use may cause hypogonadism and hyperprolactinemia which may decrease fertility in patients of reproductive potential. Menstrual cycle disorders (including amenorrhea), erectile dysfunction, and impotence have been reported. The incidence of hypogonadism may be increased with the use of opioids in high doses or long-acting opioid formulations. It is not known if the effects on fertility are reversible. Monitor patients on long-term therapy (de Vries 2020; Gadelha 2022).
Consider family planning, contraception, and the effects on fertility prior to prescribing opioids for chronic pain to patients who could become pregnant (ACOG 2017; CDC [Dowell 2022]).
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).
Maternal use of opioids may be associated with poor fetal growth, stillbirth, and preterm delivery (CDC [Dowell 2022]). Opioids used as part of obstetric analgesia/anesthesia during labor and delivery may temporarily affect the fetal heart rate (ACOG 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.
Neonatal abstinence syndrome (NAS)/neonatal opioid withdrawal syndrome (NOWS) may occur following prolonged in utero exposure to opioids (CDC [Dowell 2022]). NAS/NOWS may be life-threatening if not recognized and treated and requires management according to protocols developed by neonatology experts. Presentation of symptoms varies by opioid characteristics (eg, immediate release, sustained release), time of last dose prior to delivery, drug metabolism (maternal, placental, and infant), net placental transfer, as well as other factors (AAP [Hudak 2012]; AAP [Patrick 2020]). Clinical signs characteristic of withdrawal following in utero opioid exposure include excessive crying or easily irritable, fragmented sleep (<2 to 3 hours after feeding), tremors, increased muscle tone, or GI dysfunction (hyperphagia, poor feeding, feeding intolerance, watery or loose stools) (Jilani 2022). NAS/NOWS occurs following chronic opioid exposure and would not be expected following the use of opioids at delivery (AAP [Patrick 2020]).
Monitor infants of mothers on long-term/chronic opioid therapy for symptoms of withdrawal. Symptom onset reflects the half-life of the opioid used. Monitor infants for at least 3 days following exposure to immediate-release opioids; monitor for at least 4 to 7 days following exposure to sustained-release opioids (AAP [Patrick 2020]; CDC [Dowell 2022]). Monitor newborns for excess sedation and respiratory depression when opioids are used during labor.
When opioids are needed to treat acute pain in pregnant patients, the lowest effective dose for only the expected duration of pain should be prescribed (CDC [Dowell 2022]).
Nalbuphine is approved for use in obstetrical analgesia during labor and delivery. Opioid use for pain following vaginal or cesarean delivery should be made as part of a shared decision-making process. A stepwise multimodal approach to managing postpartum pain is recommended. A low-dose, low-potency, short-acting opioid can be used to treat acute pain associated with delivery when needed (ACOG 2021).
Opioids are not preferred for the treatment of chronic noncancer pain during pregnancy; consider strategies to minimize or avoid opioid use. Advise pregnant patients requiring long-term opioid use of the risk of NAS/NOWS and provide appropriate treatment for the neonate after delivery. NAS/NOWS is an expected and treatable condition following chronic opioid use during pregnancy and should not be the only reason to avoid treating pain with an opioid in pregnant patients (ACOG 2017; CDC [Dowell 2022]). Do not abruptly discontinue opioids during pregnancy; taper prior to discontinuation when appropriate, considering the risks to the pregnant patient and fetus if maternal withdrawal occurs (CDC [Dowell 2022]).
Nalbuphine has also been evaluated for the management of opioid-induced pruritus following neuraxial analgesia/anesthesia in patients who have had cesarean deliveries (ACOG 2019; Jannuzzi 2016; Tubog 2019).
Nalbuphine is present in breast milk.
Studies conducted in lactating patients immediately postpartum have shown nalbuphine breast milk concentrations to be <1% of the maternal dose (Jacqz-Aigrain 2007; Wischnik 1988).
Nonopioid analgesics are preferred for lactating patients who require pain control peripartum or for surgery outside of the postpartum period. When opioids are needed for lactating patients, use the lowest effective dose for the shortest duration of time to limit adverse events in the mother and breastfeeding infant. Although breast milk concentrations of nalbuphine are limited, it is not routinely used in lactating patients for surgeries that occur outside of the postpartum period (AAP [Sachs 2013]; ABM [Martin 2018]; ABM [Reece-Stremtan 2017]; WHO 2002).
When chronic opioids are prescribed prenatally and continued postpartum, breastfeeding may be initiated to help mitigate potential newborn withdrawal; monitor both the mother and the infant (AAP [Meek 2022]; AAP [Patrick 2020]).
Monitor infants exposed to opioids via breast milk for drowsiness, sedation, feeding difficulties, or limpness (ACOG 2019). Withdrawal symptoms may occur when maternal use is discontinued, or breastfeeding is stopped.

Alternate recommendations: Subacute or chronic pain (long-term therapy outside of end-of-life or palliative care, active cancer treatment, sickle cell disease, or medication-based opioid use disorder treatment): Evaluate benefits/risks of opioid therapy within 1 to 4 weeks of treatment initiation and with dose increases. In patients with subacute pain initially treated for acute pain, reassess pain and function after 30 days to address potentially reversible causes of pain and prevent unintentional long-term opioid therapy. In patients on long-term therapy, reevaluate benefits/risks every 3 months during therapy or more frequently in patients at increased risk of overdose or opioid use disorder. Toxicology testing is recommended prior to initiation and at least yearly (includes controlled prescription medications, illicit drugs of abuse, and benzodiazepines). State prescription drug monitoring program data should be reviewed by clinicians prior to initiation and periodically during therapy (frequency ranging from every prescription to every 3 months) (CDC [Dowell 2022]).
