About Contrave
Generic Contrave (Bupropion,Naltrexone) combines two well-studied agents to support weight-management efforts in adults whose body-mass index (BMI) is ≥ 30 kg/m², or ≥ 27 kg/m² with at least one obesity-related condition such as hypertension or dyslipidaemia. Bupropion, a norepinephrine-dopamine reuptake inhibitor, and naltrexone, an opioid-receptor antagonist, are co-formulated in a single 8 mg/90 mg pill. The product is approved by the U.S. Food and Drug Administration and the European Medicines Agency for chronic weight control, but it has not received registration from the Therapeutic Goods Administration in Australia. For Australian residents, access typically occurs through specialised online-pharmacy channels that source the medication from overseas licences.
What is Generic Contrave (Bupropion,Naltrexone)?
Generic Contrave (Bupropion,Naltrexone) is a fixed-dose combination tablet belonging to the class of centrally acting appetite-suppressants. The TGA has not listed the product for domestic use, so it is considered an unregistered therapeutic option in Australia. In jurisdictions where it is approved, it is indicated as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management. The combination leverages the complementary mechanisms of its two ingredients to target both the hypothalamic appetite centre and the mesolimbic reward pathway, offering a dual approach to curb excessive caloric intake.
How Contrave Works
Contrave exerts its effect through two separate pharmacological actions that converge on eating behaviour. Bupropion blocks the reuptake of norepinephrine and dopamine, raising their synaptic concentrations. Elevated dopamine in the hypothalamic pro-opiomelanocortin (POMC) neurons stimulates anorexigenic signalling, which reduces hunger sensations. Simultaneously, naltrexone binds competitively to μ-opioid receptors, preventing the autoinhibitory feedback that normally dampens POMC neuron activity. By antagonising this feedback loop, naltrexone prolongs the appetite-suppressing signal initiated by bupropion.
Pharmacokinetically, bupropion reaches peak plasma concentrations within 3 hours after oral ingestion and is metabolised principally by CYP2B6 to active metabolites (hydroxy-bupropion). Naltrexone attains peak levels in about 1 hour and is cleared primarily via hepatic glucuronidation. The fixed-dose tablet is designed for once-daily dosing, with a half-life of approximately 21 hours for bupropion's metabolites and 4 hours for naltrexone, supporting steady-state concentrations after a 2-week titration period.
Why Contrave is Used for Weight Management Conditions
- Targeting neuro-chemical drivers of appetite - The bupropion component modulates dopaminergic pathways that influence reward-related eating, while naltrexone curtails opioid-mediated reinforcement of high-calorie foods. This synergy directly addresses the physiological basis of overeating.
- Evidence-based efficacy - Phase III trials (COR-I and COR-II) demonstrated an average weight loss of 5-9 % of initial body weight over 56 weeks when combined with lifestyle modification, surpassing the 3 % threshold commonly defined as clinically meaningful.
- Guideline endorsement - The American Association of Clinical Endocrinology (AACE) and the European Association for the Study of Obesity (EASO) list Contrave as a recommended pharmacologic adjunct after behavioural therapy failure.
- Convenient dosing - A single pill delivers both agents, simplifying regimens compared with separate prescriptions of bupropion and naltrexone.
- Complementary to other modalities - It can be positioned before or after bariatric surgery, and may be combined with metformin in patients with insulin resistance, provided safety monitoring is observed.
Off-Label and Investigational Uses of Contrave
Limited studies have explored Contrave for smoking cessation, leveraging bupropion’s established anti-nicotine properties, and for reducing alcohol cravings, where naltrexone’s opioid antagonism is beneficial. Small pilot trials reported modest reductions in cigarette consumption and binge-drinking episodes, but neither indication is approved by the TGA or major regulatory bodies.
Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Contrave Right for You?
Ideal candidates are adults with a BMI ≥ 30 kg/m², or ≥ 27 kg/m² with comorbidities such as type 2 diabetes, hyperlipidaemia, or obstructive sleep apnoea, who have already engaged in dietary counselling and regular exercise. The medication may be less suitable for individuals with a history of seizure disorders, uncontrolled hypertension, or those currently receiving monoamine-oxidase inhibitors, because bupropion lowers the seizure threshold and can elevate blood pressure. Pregnant or lactating women should avoid Contrave, as safety data are insufficient. Renal impairment does not markedly affect drug levels, but severe hepatic dysfunction may require dose adjustment or avoidance, given naltrexone’s hepatic metabolism.
Taking Contrave Effectively
Therapeutic benefit relies on a gradual titration schedule to mitigate nausea, the most common adverse effect. Patients start with one 8 mg/90 mg tablet daily for one week, increase to two tablets daily (16 mg/180 mg) in week 2, and reach the target dose of three tablets daily (24 mg/270 mg) by week 4. The tablets should be swallowed whole with water, preferably in the morning to reduce sleep-disturbance risk. Missing a dose warrants skipping it and resuming the next scheduled dose; doubling up is discouraged. Alcohol intake should be limited, as both components can potentiate central nervous system effects. For travel, keep the medication in its original container, stored at room temperature, and carry a copy of the prescription or pharmacist’s verification letter.
Understanding Side Effects and How to Manage Them
- Nausea and vomiting - Likely stem from naltrexone’s opioid receptor blockade in the gastrointestinal tract. Taking the pill with a light breakfast and maintaining the titration pace can lessen severity. If persistent, an anti-emetic such as ondansetron may be prescribed.
- Headache - May reflect central dopaminergic activity. Adequate hydration and regular sleep can help; acetaminophen is usually sufficient for relief.
- Insomnia - Bupropion’s stimulating effect can interfere with sleep. Administering the final dose at least six hours before bedtime often resolves the issue.
- Elevated blood pressure - Bupropion can cause modest sympathetic activation. Monitoring blood pressure weekly during the first month is prudent; antihypertensive therapy may need adjustment.
- Seizure risk - Though rare at therapeutic doses, patients with a prior seizure disorder should avoid Contrave. Prompt medical evaluation is essential if a seizure occurs.
Serious reactions such as hepatic injury, severe hypertension, or hypersensitivity require immediate medical attention.

Frequently Asked Questions
-
How quickly can I expect to see weight loss? Most participants in clinical trials began to notice a reduction of 1-2 kg after the first 4-6 weeks, with maximal loss occurring around the 12-month mark if lifestyle changes are maintained.
-
Do I need to continue the medication forever? Weight-loss maintenance is enhanced by ongoing therapy, but some clinicians consider a trial period of 12-18 months followed by a structured taper, especially if the patient has achieved a stable BMI.
-
Can Contrave be combined with other weight-loss drugs? Current evidence advises against concurrent use of other centrally acting appetite suppressants due to additive sympathomimetic effects and increased seizure risk.
-
Is alcohol consumption prohibited while on Contrave? Moderate intake (up to one standard drink per day) is generally tolerated, but heavy drinking may heighten the risk of hypertension and seizures; discuss your drinking patterns with a healthcare professional.
-
Will Contrave affect my cholesterol levels? Studies have shown modest improvements in HDL-cholesterol and triglycerides as a secondary benefit of weight loss, though the drug itself does not directly modify lipid metabolism.
-
What should I do if I miss several days of dosing? Contact the pharmacy or your prescriber; a short-term interruption is acceptable, but prolonged gaps can reduce efficacy and may necessitate re-initiation at a lower titration level.
-
Are there any dietary restrictions while taking Contrave? No specific food bans exist, but patients are encouraged to limit high-glycaemic and highly processed foods to maximise the medication’s effect on appetite control.
-
How does Contrave differ from pure bupropion therapy? While bupropion alone modestly suppresses appetite, the addition of naltrexone amplifies the anorectic signal by preventing opioid-mediated feedback inhibition, resulting in greater weight loss.
-
Is there a risk of dependence on Contrave? Neither bupropion nor naltrexone possesses addictive properties; however, psychological reliance on medication for weight control should be addressed with behavioural support.
-
Can I use Contrave if I have depression? Bupropion is an antidepressant, and some patients experience mood improvement, but careful monitoring is essential because abrupt discontinuation may precipitate depressive symptoms.
-
What monitoring is required during therapy? Baseline and periodic assessment of blood pressure, heart rate, weight, and mental health status are recommended; liver function tests are advisable for patients with known hepatic disease.
