Naltrexone / bupropion, explained by our clinical team
What it is
Contrave® pairs two older medicines: naltrexone, used for alcohol and opioid dependence, and bupropion, an antidepressant also used to stop smoking. Together they act on the brain's hunger and reward pathways rather than on the gut.
It is a non-injectable, non-GLP-1 choice that suits people who struggle more with cravings and emotional eating than with portion size.
FDA-approved uses
- Chronic weight management in adults with a BMI of 30 or more, or 27 or more with high blood pressure, type 2 diabetes or high cholesterol
Our doctors prescribe for approved uses. Any other use is a decision made only by your doctor, for you, after evaluation.
How it is taken
Tablets are taken by mouth, increased over four weeks to two tablets in the morning and two in the evening. They should not be taken with a high-fat meal.
What to expect
Cravings and appetite usually ease within the first month. Nausea, constipation, headache and trouble sleeping are the most common side effects. If 5% of body weight has not been lost by 12 weeks on the full dose, the medicine is usually stopped.
Who should not take it
- Uncontrolled high blood pressure
- Seizure disorders or eating disorders
- Anyone taking opioids or opioid-containing medicines
- Abrupt stopping of alcohol or sedatives
- Use with MAO inhibitors
Questions we hear
Is this a stimulant?
No. Bupropion can feel activating, but Contrave® is not a controlled substance.
Will it affect my mood?
Bupropion carries a warning about mood changes and suicidal thoughts in younger adults. Tell your doctor about any history of depression.
Can I take it with a GLP-1?
Sometimes, under medical supervision. Your doctor will decide.
