## At a glance
Ozempic is a brand name for semaglutide, a GLP-1 receptor agonist made by Novo Nordisk and FDA-approved for type 2 diabetes (with an added indication to reduce cardiovascular risk in people who also have heart disease). It is the same molecule as Wegovy, which is the version approved for chronic weight management. People often lose weight on Ozempic, but the large obesity trial figures quoted in the media come from the Wegovy program, not from Ozempic’s diabetes studies.

## Facts
- **Molecule:** semaglutide
- **How it works:** a GLP-1 receptor agonist
- **Maker:** Novo Nordisk
- **Form:** a once-weekly injection
- **FDA-approved for:** type 2 diabetes (and, in adults with type 2 diabetes and heart disease, reducing cardiovascular risk)
- **Sibling brand:** Wegovy — the same molecule, approved for weight management
