Is contrave the brand name or the generic name?

Contrave is the brand name.
The drug’s generic formulation is a fixed‑dose combination of bupropion and naltrexone. In the U.S., the FDA has approved the combination under the brand name Contrave (by Sanofi). So if you see “Contrave” on a prescription or label, that’s the marketed name; the underlying active ingredients are bupropion and naltrexone.
