Contrave for Weight Loss: Naltrexone/Bupropion Guide
Contrave combines extended-release naltrexone and bupropion for chronic weight management. It may be useful for selected patients but requires careful review of opioid use, seizure risk, blood pressure and mental-health history.
What patients should know
Naltrexone is an opioid antagonist and bupropion affects norepinephrine and dopamine pathways. Tablets are escalated gradually. Because naltrexone blocks opioids, undisclosed pain medicine, cough medicine, opioid-use treatment or intermittent opioid use can create serious problems.
The label uses an early response checkpoint: if an adult has not lost the specified percentage of baseline weight after 12 weeks at the maintenance dose, continued treatment is unlikely to produce clinically meaningful loss.
Who may be evaluated
- Eligible adults seeking a non-GLP-1 tablet
- Patients not using opioids and not undergoing acute opioid withdrawal
- People without seizure disorder, uncontrolled hypertension or relevant eating disorders
- Patients who can follow escalation and monitoring
Potential advantages
- Oral non-incretin treatment
- May address appetite and reward-related eating pathways
- No injection required
- Defined response assessment
At-a-glance comparison
| Issue | Why it matters |
|---|---|
| Opioid use | Naltrexone blocks opioids and can precipitate withdrawal or impair analgesia |
| Seizure risk | Bupropion lowers seizure threshold |
| Blood pressure | Contrave can increase blood pressure and heart rate |
| Early response | Label-directed checkpoint helps avoid ineffective continuation |
Safety and medical supervision
- Contraindicated with uncontrolled hypertension, seizure disorders, anorexia or bulimia, chronic opioid use, acute opioid withdrawal, certain abrupt substance withdrawals, MAOI use and pregnancy.
- Bupropion-containing products carry a boxed warning regarding suicidal thoughts and behaviors in children, adolescents and young adults; Contrave is not approved for depression or smoking cessation.
- Blood pressure and pulse should be monitored.
- Patients may need a planned opioid-free interval before treatment; never conceal opioid use.

Frequently asked questions
Can Contrave be used with opioid pain medicine?

Is Contrave an antidepressant?
It contains bupropion, but Contrave itself is approved for weight management and is not approved to treat depression.
Does it require dose escalation?
Yes. The tablets are increased according to the prescribing schedule rather than started at the full maintenance dose.
