Tier 1: Contrave vs GLP-1 Medications (The Big Comparison)
This is the comparison that matters most in 2026. GLP-1 receptor agonists are the dominant anti-obesity drug class — semaglutide, tirzepatide, and liraglutide — and most conversations about weight loss medication now start here.
Contrave vs GLP-1 (Summary)
| Feature | Contrave | GLP-1 (Semaglutide / Tirzepatide) |
|---|---|---|
| Drug Class | Antidepressant + opioid antagonist | Hormone-based GLP-1 agonist |
| 1-Year Weight Loss | 5–8% | 15–22% |
| Route | Oral (4 pills/day) | Injection (1x/week) |
| Black Box Warning | Yes — suicidality | No (thyroid in rodents) |
| Seizure Risk | Yes | No |
| Alcohol | Must avoid | Moderation OK |
| Opioid Use | Contraindicated | No interaction |
| Available via telehealth | Limited | Widely — from $179/mo |
You just read the comparison. Here's the better option:
- 15–22% weight loss (vs 5–8% Contrave)
- 1x weekly injection (vs 4 pills per day)
- No seizure risk, no black box warning
- From $179/month — delivered to your door
- Money-back guarantee
- 500,000+ patients. No insurance needed.
Contrave vs Wegovy (Semaglutide 2.4 mg)
Wegovy is semaglutide dosed specifically for weight management — the same molecule as Ozempic but at a higher dose indicated for weight loss rather than diabetes.
| Feature | Contrave | Wegovy |
|---|---|---|
| Avg. weight loss (trial) | −6.1% (COR-I) | −14.9% (STEP-1) |
| Trial duration | 56 weeks | 68 weeks |
| Route / frequency | Oral, 4/day | SC injection, 1/week |
| Titration | 4 weeks | 16 weeks |
| GI side effects | Nausea 32%, constipation 19% | Nausea 44%, constipation 24% |
| CNS side effects | Insomnia 9%, anxiety | Minimal |
| Cost / month retail | $100 (gen) – $750 (brand) | $1,350 (brand) |
Verdict: Wegovy wins on efficacy by a wide margin. Contrave wins only on raw monthly cost if you have access to the generic and are paying cash.
Contrave vs Zepbound (Tirzepatide)
Zepbound is tirzepatide dosed for weight management — the most effective anti-obesity medication ever FDA-approved.
| Feature | Contrave | Zepbound |
|---|---|---|
| Avg. weight loss (trial) | −6.1% | −20.9% (SURMOUNT-1) |
| Mechanism | Dual CNS (appetite + reward) | Dual incretin (GLP-1 + GIP) |
| Route / frequency | Oral, 4/day | SC injection, 1/week |
| Titration | 4 weeks | 20 weeks |
| Insomnia risk | Yes | No |
| Seizure risk | Yes | No |
| Retail price | $100–$750 | ~$1,060 (brand) |
Verdict: Zepbound produces approximately 3x the weight loss with a cleaner safety profile. The cost differential is meaningful, but the cost-per-pound analysis favors Zepbound.
Contrave vs Ozempic
Ozempic is semaglutide dosed for type 2 diabetes — the same molecule as Wegovy at a lower maximum dose. It is not FDA-approved for weight loss, but is prescribed off-label for that purpose.
| Feature | Contrave | Ozempic (1 mg) |
|---|---|---|
| FDA-approved for | Weight loss | Type 2 diabetes |
| Avg. weight loss | −6.1% | −6.8% at 1 mg (STEP studies at higher doses ~14%) |
| Primary indication | Obesity | Glycemic control |
| Black box warning | Suicidality | Thyroid C-cell tumors (rodent data) |
| Cost / month | $100–$750 | ~$970 (brand) |
Verdict: Ozempic at 1 mg produces comparable weight loss to Contrave. Ozempic at higher doses (as Wegovy) produces substantially more. If your clinical situation includes both obesity and diabetes, Ozempic is typically a better starting point than Contrave.
Contrave vs Mounjaro
Mounjaro is tirzepatide for type 2 diabetes — same molecule as Zepbound. Comparable distinction to Ozempic/Wegovy.
Quick verdict: If you have diabetes, Mounjaro is far more effective for weight loss than Contrave (approximately 3x) and also improves glycemic control. For weight-loss-only patients without diabetes, Zepbound is the labeled equivalent.
Contrave vs Semaglutide (Generic / Compounded)
Compounded semaglutide — available through telehealth from ~$179/month — has become one of the most common weight loss options in the U.S.
| Feature | Contrave | Compounded Semaglutide |
|---|---|---|
| Avg. weight loss | −6.1% | ~12–15% (clinic data) |
| Monthly cost | $100–$750 | ~$179–$299 |
| Route | Oral 4/day | SC injection 1/week |
| FDA approval | Yes | Custom-compounded by 503A/503B pharmacies |
| Telehealth availability | Limited | Very wide |
Verdict: Compounded semaglutide offers GLP-1 efficacy at a price competitive with brand Contrave and not far above generic Contrave.
Tier 2: Contrave vs Old-School Weight Loss Pills
Before GLP-1s, anti-obesity medication was dominated by stimulant-based drugs (phentermine, diethylpropion, benzphetamine) and combination products (Qsymia).
Contrave vs Phentermine
| Feature | Contrave | Phentermine (Adipex-P) |
|---|---|---|
| Class | Antidepressant + opioid antagonist | Sympathomimetic stimulant |
| DEA Schedule | Not scheduled | Schedule IV |
| Approved for | Chronic (indefinite) | Short-term (typically ≤12 weeks) |
| Avg. weight loss | −6.1% | −5 to −7% over 12 weeks |
| Major concerns | Seizure, mood, alcohol | Cardiovascular, dependence |
| Cost | $100–$750 | $15–$40 |
Verdict: Phentermine produces faster short-term results but cannot be used long-term. Contrave allows long-term use but at the cost of a more complex safety profile. Neither matches GLP-1.
Contrave vs Qsymia
Qsymia combines phentermine with topiramate (an anti-seizure medication used off-label for weight loss since the late 1990s).
| Feature | Contrave | Qsymia |
|---|---|---|
| Ingredients | Naltrexone + bupropion | Phentermine + topiramate |
| DEA Schedule | Not scheduled | Schedule IV (phentermine) |
| Avg. weight loss | −6.1% | −8 to −10% |
| Special program | None | REMS (birth defect risk) |
| Pregnancy | Not recommended | Contraindicated (category X) |
| Seizure risk | Yes | Rare |
Verdict: Qsymia wins on efficacy but carries REMS requirements and pregnancy contraindication. Contrave has no REMS but inherits the bupropion black box. Neither approaches GLP-1 weight loss.
Contrave vs Adipex
Adipex-P is simply brand-name phentermine — same molecule as generic phentermine. See the phentermine section above.
Not satisfied with any of these? Here's the alternative we rated highest:
- 15–22% weight loss (vs 5–8% Contrave)
- 1x weekly injection (vs 4 pills per day)
- No seizure risk, no black box warning
- From $179/month — delivered to your door
- Money-back guarantee
- 500,000+ patients. No insurance needed.
Tier 3: Contrave vs Its Own Ingredient (Wellbutrin)
One of the most-asked Contrave questions: why not just take Wellbutrin (bupropion) by itself?
Contrave vs Wellbutrin
| Feature | Contrave | Wellbutrin (Bupropion) |
|---|---|---|
| Active ingredients | Naltrexone 8 mg + bupropion 90 mg | Bupropion 150–300 mg |
| FDA-approved for | Weight loss | Depression, smoking cessation |
| Weight loss mechanism | Appetite + cravings (dual) | Appetite only |
| Avg. weight loss (12 mo) | −6.1% | ~−1 to −3% (incidental) |
| Cravings effect | Significant (naltrexone) | Minimal |
| Cost / month (generic) | ~$100 | ~$10–$30 |
Verdict: Wellbutrin alone produces mild incidental weight loss in some patients but is not FDA-approved for weight management. The naltrexone in Contrave is what unlocks the full effect (via cravings reduction). This is also why DIY bupropion + naltrexone attempts don't reliably reproduce Contrave's results — see our DIY guide.

Frequently Asked Questions
Is Contrave better than Wegovy?
For weight loss effectiveness, no. Wegovy (semaglutide 2.4 mg) produces approximately 14.9% average body weight loss over 68 weeks, versus Contrave's 5–8% over 56 weeks — roughly 2–3x more weight loss. Contrave may be preferable if you cannot tolerate injections or cannot afford Wegovy brand.
Is Contrave better than Phentermine?
It depends on priority. Contrave delivers more sustained weight loss (because phentermine is only approved short-term, typically 12 weeks). Phentermine produces faster initial results but is a Schedule IV controlled substance with abuse potential. Contrave is not scheduled but has a black box warning.
Is Contrave better than Qsymia?
Qsymia produces slightly more weight loss than Contrave (~8–10% vs 5–8%) but requires REMS program enrollment due to birth defect risk from topiramate. Contrave has no REMS but carries a black box warning for bupropion. Neither matches GLP-1 efficacy.
Is Contrave better than Zepbound?
No. Zepbound (tirzepatide) produces the largest weight loss of any FDA-approved anti-obesity medication — approximately 20.9% average body weight loss in SURMOUNT-1 over 72 weeks. That is approximately 3x Contrave's typical result, and with 1x weekly dosing vs 4 pills per day.
Is Contrave the same as Wellbutrin?
No. Contrave contains bupropion (the active ingredient in Wellbutrin) at 360 mg daily plus naltrexone. Wellbutrin by itself is an antidepressant — not approved for weight loss, though mild weight loss is a known side effect. The naltrexone component in Contrave adds cravings reduction and is what differentiates the two.
Can you switch from Contrave to a GLP-1?
Yes. There is no required washout period between Contrave and a GLP-1 medication. Many patients transition to semaglutide or tirzepatide when Contrave produces insufficient results. Do not combine them without physician supervision — overlapping appetite suppression plus additive nausea can be significant.
