In context

Semaglutide is a once-weekly GLP-1 receptor agonist approved for type 2 diabetes and, at a higher dose, for weight management. In large randomised trials it produces roughly 15% average weight loss over 68 weeks and reduces major cardiovascular events in people with existing heart disease. Gastrointestinal side effects are common and are the main reason people stop. It is a prescription medicine; products sold outside that channel are unlicensed copies.

Semaglutide is approved (rx). Legal status differs by country — see the regulation section or the jurisdiction pages.
