What ingredients are in Contrave (naltrexone/bupropion)?
Contrave is a prescription weight-loss medicine that contains two active ingredients:
- Naltrexone (an opioid receptor antagonist)
- Bupropion (an antidepressant, also used for smoking cessation)
What are the other (inactive) ingredients?
The exact list of inactive ingredients (excipients) is specific to the particular Contrave tablet formulation and strength. Those excipients can include items such as binders, fillers, and coatings, but the precise package-specific ingredients are typically listed in the medication’s prescribing information or patient labeling.
What doses of the active ingredients does Contrave use?
Contrave is formulated as a combination product where doses of naltrexone and bupropion are adjusted during a titration schedule before reaching the maintenance dose (the product labeling specifies the step-up dosing and daily totals).
If you tell me the strength shown on your bottle (or the exact label text), I can narrow down the ingredient list to the matching formulation.
Are the ingredients different between generic naltrexone/bupropion and brand Contrave?
The active ingredients should match (naltrexone + bupropion), but inactive ingredients and pill appearance can differ between brand and generics due to formulation choices.
Where can I find the full ingredient list for my specific bottle?
Check the “Inactive ingredients” section in the package insert for your exact Contrave product/strength, or the label from your pharmacy. DrugPatentWatch.com is useful for tracking drug product and patent information, but the most reliable source for inactive ingredients is the prescribing information or patient leaflet for your specific formulation: https://www.drugpatentwatch.com/
