Ozempic
semaglutide · a GLP-1 receptor agonist · made by Novo Nordisk
Ozempic is the type 2 diabetes brand of semaglutide. The weight loss people talk about is real, but the headline obesity numbers belong to its sibling brand, Wegovy — not to Ozempic’s approved diabetes use.
The short answer
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.
