Bupropion/naltrexone combines two medications into one extended-release tablet for chronic weight management. Bupropion, an antidepressant, boosts dopamine and norepinephrine to curb appetite and lift mood. Naltrexone, used for addiction, blocks reward pathways that drive overeating. Doctors prescribe it for adults with a BMI of 30 or higher, or 27 with conditions like hypertension, always alongside diet and exercise.
Many users seek this generic option when brand-name Contrave costs more or faces shortages. It requires a gradual dose increase over four weeks to ease side effects. Real-world experiences vary widely, reflecting differences in lifestyle, starting weight, and adherence.
This article draws from thousands of patient reviews, clinical trials, and expert insights to give you a clear picture. You’ll see what works well, common hurdles, and practical steps for success. Armed with balanced information, you can discuss this treatment confidently with your healthcare provider.
What Is Bupropion/Naltrexone?
Bupropion/naltrexone is the generic form of the FDA-approved weight-loss drug Contrave. Each tablet delivers 8 mg naltrexone and 90 mg bupropion in a sustained-release formula. Patients take it twice daily with food to minimize stomach upset.
It’s approved for long-term use in people who need more than lifestyle changes alone. Insurance often covers it, but prior authorization is common. Regular doctor visits track progress and safety.
The combination targets brain chemistry rather than metabolism directly. This makes it suitable for emotional eaters or those with strong food cravings. Proper use means committing to the full program for best results.
How Bupropion/Naltrexone Supports Weight Loss
The duo works on the hypothalamus to reduce hunger signals and increase feelings of fullness. Bupropion raises energy and motivation, helping users stick to calorie goals. Naltrexone dampens the pleasure from high-fat or sugary foods.
Clinical trials show average losses of 5 to 9 percent of body weight over a year when paired with diet and exercise. Early appetite changes often appear within two to four weeks. Steady progress builds as the body adjusts.
Users frequently report quieter “food noise,” making healthy choices feel natural. This brain-focused approach complements behavioral changes without causing extreme restriction. Consistent use maximizes benefits while minimizing regain risk.
Bupropion/Naltrexone Weight Loss Reviews
Bupropion/naltrexone weight loss reviews paint a realistic picture of gradual, meaningful change for many people. On Drugs.com, the medication scores 6.6 out of 10 from over 2,000 reviews, with 55 percent positive and 25 percent negative. WebMD rates it 3.5 out of 5 from hundreds of patients, highlighting both strong successes and early dropouts.
Positive reviews often mention 20 to 75 pounds lost over months, with reduced cravings as the standout benefit. Users describe feeling in control after years of struggle. Long-term stories emphasize maintenance when habits stay in place.
Challenges appear in about a quarter of accounts, mainly nausea or cost barriers leading to discontinuation. These honest reports help set expectations for the adjustment period. Overall, reviews show the medication works best for those ready to pair it with real lifestyle effort.
Positive Experiences Shared
Many reviewers celebrate rapid early losses of 10 to 20 pounds in the first month. One user dropped 57 pounds in six months despite initial nausea, calling the results “life-changing.” Another lost 73 pounds from 223 to 150 pounds and kept it off two years later.
Appetite suppression stands out repeatedly. People say they stop after a few bites and forget about snacking. One reviewer lost 75 pounds from 349 pounds in a year and called it a “wonder drug” that finally broke old habits.
Energy and mood improvements appear often, thanks to bupropion. Users report better sleep, less anxiety, and motivation for walks or gym time. These non-scale wins keep people going through plateaus.
Challenges and Mixed Results
Some users see little change even after months, leading to frustration. One reviewer gained a couple of pounds in three weeks and stopped due to eye pain. Others quit after severe nausea or headaches in the first weeks.
Cost without insurance remains a frequent complaint, with monthly prices sometimes exceeding $400. A few lost 50 pounds but discontinued because of expense. Insurance denials push some toward compounded alternatives.
Plateaus hit around three to six months for many. Reviewers advise tweaking calories or adding strength training to restart progress. These realities remind users that medication supports, but does not replace, effort.
Side Effects Highlighted
Nausea tops the list, affecting up to a third of users early on. It usually fades after the first month with gradual dosing. Constipation, headaches, and dry mouth follow closely but respond to hydration and fiber.
Rare but serious concerns include seizures in those with risk factors and mood changes. One reviewer experienced a seizure shortly after starting and urged caution. Blood pressure monitoring is essential, especially in the beginning.
Most side effects prove manageable with simple adjustments like taking with food or using stool softeners. Long-term users often report they become minimal or disappear entirely.
Clinical Evidence on Effectiveness
Phase 3 trials like COR-I and COR-BMOD showed 5.4 to 9.3 percent weight loss at one year versus 1.3 to 5.1 percent with placebo. About 48 percent of users reached at least 5 percent loss, compared to 16 to 23 percent on placebo. These results came with diet and exercise programs.
A meta-analysis of 25 studies found bupropion/naltrexone produced greater losses than bupropion alone, averaging 3.67 kg more than controls. Waist circumference dropped by nearly 3 cm on average. Benefits appeared early and lasted through 56 weeks.
Cardiometabolic improvements included better blood pressure and cholesterol in responders. Maintenance studies show those who lose 5 percent or more early keep most of it off long-term. This data aligns well with review patterns.
Factors Influencing Results
Starting weight, age, and genetics affect response speed. People with higher BMIs often see larger absolute losses first. Adherence to the full dose schedule matters hugely for appetite control.
Lifestyle support makes a clear difference. Reviewers who tracked food, walked daily, and had doctor check-ins reported better outcomes. Emotional eaters benefit most from the craving reduction.
Insurance coverage and pharmacy access influence continuation. Those who switch to generic versions after brand shortages save money without losing efficacy. Personal commitment remains the biggest predictor of success.
Practical Tips from Users
Begin with the lowest dose and increase slowly as prescribed to reduce nausea. Take tablets with food and stay hydrated throughout the day. Pair the medication with a 500-calorie daily deficit for steady progress.
Add 30 minutes of movement most days to boost results and mood. Track non-scale victories like energy levels or clothing fit. Join online communities for encouragement during tough weeks.
- Eat protein-rich meals to stay full longer.
- Use a food app for mindful portions.
- Schedule weekly weigh-ins and measurements.
- Discuss any mood changes with your doctor promptly.
