Contrave Reviews: The Honest Summary
Patient reviews of Contrave are the most polarized of any anti-obesity medication. Responders love it. Non-responders abandon it. The bimodal distribution is not random — it reflects a drug that works via brain chemistry, which varies significantly between individuals.
Aggregating patient reports and clinical trial data:
- ~50% of patients achieve clinically meaningful weight loss (≥5%)
- ~25–30% of patients achieve substantial weight loss (≥10%)
- ~25% of patients discontinue due to side effects within the first 3 months
- ~25% of patients continue but see minimal results
1 Month Contrave Results
The first month of Contrave is the titration period. You reach full dose only at the start of week 4. This means 1-month results are typically modest — and often reflect early water weight + initial appetite suppression rather than sustained fat loss.
Typical 1-month results
“First week was rough. Nausea, headache, couldn't sleep. By week 3 the cravings for sweet stuff were genuinely diminished, which I did not expect. Lost 6 pounds by the end of month 1.”
“Side effects were terrible for the first two weeks. Down 3 pounds at the one-month mark, which wasn't enough to justify how I felt. Stopped at month 2.”
What 1-month pictures usually show
Most 1-month before-and-after pictures shared online show modest changes — face less puffy, slightly less abdominal bloating. Dramatic visual transformation in 30 days is not typical on Contrave and is more characteristic of GLP-1 medications at higher doses.
3 to 6 Month Results
Months 3–6 are where Contrave shows what it can do. You have been at full dose long enough for the drug's mechanism to work. This is also the window in which FDA guidance says you should be re-evaluated.
Typical 3-month results (at full dose)
Typical 6-month results
“Down 18 lbs at 6 months. My cravings for chips and cookies basically evaporated. That part was the game-changer for me. Dosing 4 times a day is annoying but doable.”
1-Year Results
The pivotal Phase 3 Contrave trials reported 56-week outcomes. Here are the real numbers:
| Trial | Contrave 32/360 Avg. Loss | Placebo Loss | % Achieving ≥5% |
|---|---|---|---|
| COR-I | −6.1% | −1.3% | 48% |
| COR-II | −6.4% | −1.2% | 50.5% |
| COR-BMOD (w/ intensive lifestyle) | −9.3% | −5.1% | 66.4% |
| COR-Diabetes | −5.0% | −1.8% | 44.5% |
Contrave Before and After
Before-and-after images of Contrave users — particularly at the 6–12 month mark — typically show visible but not dramatic change: reduction in abdominal circumference, improved facial definition, clothing size drop of 1–2 sizes.
By contrast, GLP-1 before-and-after photos at the same timeframe frequently show larger visible change (3–4 clothing sizes, more pronounced body composition change) — consistent with the 2–3x greater average weight loss.

How Long Does It Take Contrave to Work?
| Timeframe | What to Expect |
|---|---|
| Week 1 | Initial side effects (nausea, headache). Minimal weight change. One pill per day. |
| Week 2–3 | Titration continues. Mild appetite suppression may begin. |
| Week 4 | Full dose reached. Cravings reduction becomes noticeable. |
| Week 6–8 | Measurable weight loss in responders. Plateau possible for non-responders. |
| Week 12 | FDA re-evaluation point. Continue only if ≥5% loss. |
| Week 26 | Half of total 1-year loss typically achieved. |
| Week 56 | Maximal expected loss (6–8% avg). |
Contrave Success Stories
“I had tried everything. Weight Watchers, keto, two rounds of phentermine — nothing stuck. Contrave worked because it did something the others didn't: it killed my sugar cravings. I lost 34 pounds in 14 months and have kept 28 off for another year. Not everyone will respond like this but for me it was the right drug.”
“Bupropion also treated depression that had been creeping back. Two problems, one medication. Down 21 lbs in 10 months.”
Why Contrave Doesn't Work for Everyone
About half of patients don't meet the 5% threshold. Common reasons:
- No cravings-driven eating pattern — naltrexone's main benefit is reducing hedonic food reward. If your weight gain is driven by hormones, metabolic disease, or portion size (not cravings), you may not respond.
- Genetic variation in CYP2B6 — patients with rapid bupropion metabolism achieve lower blood levels and may see less effect.
- Side effects limiting titration — some patients cannot tolerate the ramp-up and never reach the therapeutic dose.
- Wrong mechanism for the patient — GLP-1 deficiency or insulin resistance is better addressed by GLP-1 agonists.
Foods to Avoid on Contrave
- High-fat meals — cause 30–80% increase in peak drug levels → more side effects
- Alcohol — seizure risk, altered effects due to naltrexone
- Grapefruit and grapefruit juice — affects bupropion metabolism
- Large amounts of caffeine — additive stimulation during titration
- Tyramine-rich foods (aged cheeses, cured meats) — less of an issue than with MAOIs, but worth moderating
Nothing is strictly prohibited except alcohol. But avoiding high-fat meals during the titration makes a meaningful difference in side effect intensity.
What to Do When You Hit a Plateau on Contrave
Weight loss plateaus are nearly universal. Strategies that actually work:
- Re-audit calorie intake — tracking tends to degrade after 8–10 weeks
- Add or increase resistance training — preserves muscle mass and metabolic rate
- Increase protein to 1.2–1.6 g/kg body weight
- Reassess sleep — poor sleep sabotages appetite regulation
- Consider switching medications — if plateau is at 6 months with <5% total loss, the drug may not be the right fit

Frequently Asked Questions
How long does it take for Contrave to work?
Most patients see initial effects on hunger and cravings by week 3–4 (once at full dose). Meaningful weight loss typically begins at 4–8 weeks. FDA guidance: if you have not lost at least 5% of body weight by 12 weeks at target dose, discontinue Contrave — continuing rarely produces results.
How quickly does Contrave work?
Effects on appetite and cravings usually appear in weeks 3–4. Visible weight loss typically starts around week 4–6. Dramatic early loss (>5 lbs in the first 2 weeks) is uncommon on Contrave because of the 4-week titration schedule.
How much weight can you lose on Contrave?
The average 1-year weight loss on Contrave at full dose is 5–8% of body weight. For a 200-lb person, that is 10–16 lbs. Approximately 48–50% of patients achieve ≥5% weight loss. Approximately 25–30% achieve ≥10% weight loss. The best responders may lose 15–25%, though this is uncommon.
What is the average weight loss on Contrave?
Across the pivotal COR-I and COR-II trials, average weight loss was 6.1–6.4% at 56 weeks on Contrave 32/360 mg. With intensive behavioral modification (COR-BMOD), average loss increased to 9.3%.
What foods should I avoid on Contrave?
Avoid high-fat meals (they increase peak drug levels and side effects), alcohol (seizure risk, altered effects from naltrexone), and grapefruit juice (affects bupropion metabolism). Also limit caffeine during titration to minimize jitteriness and insomnia.
Do Contrave results last after stopping?
No. Like virtually all anti-obesity medications (including GLP-1s), weight tends to return within 6–12 months of stopping Contrave. This is not drug dependence — it reflects obesity as a chronic condition. If you lose weight on Contrave and want to maintain it, you will need a maintenance strategy (lifestyle, continued medication, or transition to another anti-obesity medication).
