Naltrexone is a pure opioid antagonist, and bupropion is a relatively weak inhibitor of the neuronal reuptake of dopamine and norepinephrine. The exact neurochemical effects of naltrexone/bupropion leading to weight loss are not fully understood. Effects may result from action on areas of the brain involved in the regulation of food intake: the hypothalamus (appetite regulatory center) and the mesolimbic dopamine circuit (reward system).
Use: Labeled Indications
Weight management: Adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults with an initial body mass index (BMI) of ≥30 kg/m2 or ≥27 kg/m2 in the presence of at least one weight-related comorbid condition (eg, hypertension, type 2 diabetes mellitus, and/or dyslipidemia)
Limitations of use: The effect of naltrexone/bupropion on cardiovascular morbidity and mortality has not been established. The safety and effectiveness of naltrexone/bupropion in combination with other products intended for weight loss, including prescription drugs, over-the-counter drugs, and herbal preparations, have not been established.
Hypersensitivity to bupropion, naltrexone, or any other component of the formulation; concomitant use of other bupropion-containing products (eg, including [but not limited to] Wellbutrin, Wellbutrin SR, Wellbutrin XL, Aplenzin, Zyban); chronic opioid, opiate agonist (eg, methadone) or partial agonist (eg, buprenorphine) use; acute opioid withdrawal; uncontrolled hypertension; seizure disorder or a history of seizures; bulimia or anorexia nervosa; abrupt discontinuation of alcohol, benzodiazepines, barbiturates, and antiepileptic drugs; concomitant use of MAO inhibitors (concurrently or within 14 days of discontinuing the MAO inhibitor or naltrexone/bupropion); initiation of naltrexone/bupropion in a patient receiving linezolid or intravenous (IV) methylene blue; pregnancy
Weight management: Oral:
Initial: One tablet (naltrexone 8 mg/bupropion 90 mg) once daily in the morning for 1 week; at week 2, increase to 1 tablet twice daily administered in the morning and evening and continue for 1 week; at week 3, increase to 2 tablets in the morning and 1 tablet in the evening and continue for 1 week; at week 4, increase to 2 tablets twice daily administered in the morning and evening and continue for the remainder of the treatment course.
Usual dosage: Two tablets (naltrexone 16 mg/bupropion 180 mg) twice daily (maximum dose: naltrexone 32 mg/bupropion 360 mg/day).
Concomitant Use with CYP2B6 inhibitors (eg, ticlopidine, clopidogrel): Maximum dose: 1 tablet (naltrexone 8 mg/bupropion 90 mg) twice daily
Discontinuation of therapy: If the patient has not lost at least 5% of baseline body weight after 12 weeks at the maintenance dosage, discontinue therapy; clinically meaningful weight loss is unlikely with continued treatment.
MAO inhibitor recommendations:
Switching to or from an MAO inhibitor antidepressant:
Allow 14 days to elapse between discontinuing an MAO inhibitor intended to treat depression and initiation of naltrexone/bupropion.
Allow 14 days to elapse between discontinuing naltrexone/bupropion and initiation of an MAO inhibitor intended to treat depression.
Refer to adult dosing.

Major psychiatric warnings (use in treating psychiatric disorders):
• Suicidal thinking/behavior (use in treating psychiatric disorders): [US Boxed Warning]: Naltrexone/bupropion is not approved for use in the treatment of major depressive or psychiatric disorders; it contains bupropion the same active ingredient in some other antidepressant medications. Antidepressants increase the risk of suicidal thinking and behavior in children, adolescents, and young adults (18 to 24 years of age) with major depressive disorder (MDD) and other psychiatric disorders; consider risk prior to prescribing. Short-term studies of antidepressants did not show an increased risk in patients >24 years of age and showed a decreased risk in patients ≥65 years. Closely monitor patients for clinical worsening, suicidality, or unusual changes in behavior, particularly during the initial 1 to 2 months of therapy or during periods of dosage adjustments (increases or decreases); the patient’s family or caregiver should be instructed to closely observe the patient and communicate condition with health care provider. A medication guide concerning the use of antidepressants should be dispensed with each prescription.
• The possibility of a suicide attempt is inherent in major depression and may persist until remission occurs. Worsening depression and severe abrupt suicidality that are not part of the presenting symptoms may require discontinuation or modification of drug therapy. Use caution in high-risk patients during initiation of therapy.
• Prescriptions should be written for the smallest quantity consistent with good patient care. The patient's family or caregiver should be alerted to monitor patients for the emergence of suicidality and associated behaviors such as anxiety, agitation, panic attacks, insomnia, irritability, hostility, impulsivity, akathisia, hypomania, and mania; patients should be instructed to notify their health care provider if any of these symptoms or worsening depression or psychosis occur.
Concerns related to adverse effects:
• Accidental opioid overdose: Patients treated with naltrexone may respond to lower opioid doses than previously used. This could result in potentially life-threatening opioid intoxication. Warn patients that any attempt to overcome opioid blockade during naltrexone therapy is dangerous and could potentially lead to fatal opioid overdose; the opioid competitive receptor blockade produced by naltrexone is potentially surmountable in the presence of large amounts of opioids. If chronic opiate therapy is required, naltrexone/bupropion should be stopped; if intermittent opiate therapy is required, temporarily discontinue naltrexone/bupropion and lower doses of opioids may be needed.
• Acute opioid withdrawal: May precipitate symptoms of acute withdrawal in opioid-dependent patients. An opioid-free interval of a at least 7 to 10 days is recommended for patients previously dependent on short-acting opioids (including tramadol); consider an opioid-free interval of up to 2 weeks in patients transitioning from buprenorphine or methadone.
• Cardiovascular effects: May elevate heart rate, blood pressure and cause hypertension; use is contraindicated in patients with uncontrolled hypertension. Events have been observed in patients with or without evidence of preexisting hypertension. Risks may be greater during the initial 3 months of therapy. Assess heart rate and blood pressure before initiating treatment and monitor periodically.
• Hepatotoxicity: Cases of hepatitis, significant liver dysfunction, and transient, asymptomatic hepatic transaminase elevations have been observed with naltrexone use. Discontinue therapy if signs/symptoms of acute hepatitis develop. Clinicians should note that elevated transaminases may be a result of preexisting alcoholic liver disease, hepatitis B and/or C infection, or concomitant use of other hepatotoxic drugs; abrupt opioid withdrawal may also lead to acute liver injury.
• Hypersensitivity reactions: Anaphylactoid/anaphylactic reactions have occurred, including pruritus, urticaria, angioedema, and dyspnea. Serious reactions have been (rarely) reported with bupropion, including erythema multiforme, Stevens-Johnson syndrome(SJS), and anaphylactic shock. Arthralgia, myalgia, and fever with rash and other symptoms suggestive of delayed hypersensitivity resembling serum sickness have been reported with bupropion.
• Neuropsychiatric effect: Although naltrexone/bupropion is not approved for smoking cessation, serious neuropsychiatric events have occurred in patients taking bupropion for smoking cessation, including changes in mood (eg, depression, mania), psychosis, hallucinations, paranoia, delusions, homicidal ideation, hostility, agitation, aggression, anxiety, panic, suicidal ideation, suicide attempt, and completed suicide. The majority of these reactions occurred during bupropion treatment; however some occurred during treatment discontinuation. A causal relationship is uncertain as depressed mood may be a symptom of nicotine withdrawal. Some cases also occurred in patients taking bupropion who continued to smoke. Neuropsychiatric effects occurred in patients with and without preexisting psychiatric disease; some patients experienced a worsening of their psychiatric illnesses. Observe all patients taking bupropion for neuropsychiatric reactions. Instruct patients to stop taking naltrexone/bupropion and contact a health care provider if neuropsychiatric reactions occur. Depression, suicide, attempted suicide, and suicidal ideation have also been reported with naltrexone use for the treatment of opioid dependence; however, no causal relationship has been demonstrated.
• Ocular effects: Bupropion may cause mild pupillary dilation, which in susceptible individuals can lead to an episode of narrow-angle glaucoma. Consider evaluating patients who have not had an iridectomy for narrow-angle glaucoma risk factors.
• Seizures: Bupropion may cause a dose-related risk of seizures. Use is contraindicated in patients with a seizure disorder or a history of seizures, current or past diagnosis of bulimia or anorexia nervosa, or those undergoing abrupt discontinuation of alcohol, benzodiazepines, barbiturates, and antiepileptic drugs. Use caution with concurrent use of antipsychotics, antidepressants, theophylline, systemic corticosteroids, or hypoglycemic agents, or with excessive use of ethanol, benzodiazepines, sedative/hypnotics, or opioids. Use with caution in seizure-potentiating metabolic disorders (hypoglycemia, hyponatremia, severe hepatic impairment, and hypoxia), in patients with an addiction to cocaine or stimulants, in patients withdrawing from sedatives, and in patients with a history of head trauma, severe stroke, arteriovenous malformation, or central nervous system tumor or infection. To minimize the risk of seizures, increase the dose gradually, administer the dose twice daily with no more than 2 tablets taken at a time, avoid administration with high-fat meals, skip missed doses, and limit the daily dose of bupropion to ≤360 mg. Use of multiple bupropion formulations is contraindicated. Permanently discontinue if seizure occurs during therapy.
• Cardiovascular disease: Use with caution in patients with cardiovascular disease; naltrexone/bupropion may cause an increase in blood pressure and heart rate.
• Diabetes mellitus: Weight loss may increase the risk of hypoglycemia in patients with type 2 diabetes mellitus treated with insulin and/or insulin secretagogues. Monitor blood glucose levels at baseline and periodically during treatment. Consider decreases in doses for concurrent antidiabetic medications which are non-glucose-dependent; adjust antidiabetic drug regimens if hypoglycemia develops during treatment.
• Hepatic impairment: Use with caution in patients with hepatic impairment; reduced doses are recommended.
• Mania/hypomania: Bupropion may precipitate a manic, mixed, or hypomanic episode; risk is increased in patients with bipolar disorder or who have risk factors for bipolar disorder. Screen patients for a history of bipolar disorder and the presence of risk factors including a family history of bipolar disorder, suicide, or depression. Naltrexone/bupropion is not FDA approved for bipolar depression.
Concurrent drug therapy issues:
• 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.
• Elderly: Use with caution in the elderly; may be at greater risk of drug accumulation during chronic dosing.
Blood pressure and heart rate (baseline and periodic); blood glucose (baseline and periodic); weight; BMI; renal and liver function (base and periodic); mental status for depression, suicidal ideation (especially at the beginning of therapy or when doses are increased or decreased), anxiety, social functioning, mania, and panic attacks.
Pregnancy Risk Factor
Animal reproduction studies have not been conducted with this combination. Adverse fetal events following maternal use of bupropion during pregnancy have been reported in some studies. Weight-loss therapy is not recommended for pregnant women. Obese and overweight women should be encouraged to participate in weight reduction programs prior to attempting pregnancy; weight gain during pregnancy should be determined by their prepregnancy BMI and current guidelines (ADA, 2009; IOM, 2009). Use of this product is contraindicated in pregnant women.
• 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, constipation, dry mouth, diarrhea, or insomnia. Have patient report immediately to prescriber signs of depression (suicidal ideation, anxiety, emotional instability, or confusion), signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or jaundice), agitation, irritability, panic attacks, mood changes, behavioral changes, eye pain, vision changes, eye irritation, severe dizziness, passing out, hallucinations, severe headache, seizures, angina, tachycardia, abnormal heartbeat, swollen lymph nodes, muscle pain, joint pain, shortness of breath, or signs of Stevens-Johnson syndrome/toxic epidermal necrolysis (red, swollen, blistered, or peeling skin [with or without fever]; red or irritated eyes; or sores in mouth, throat, nose, or eyes) (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.
