What's the same
Ozempic and Januvia both belong to the Diabetes Treatment class and are used for partially overlapping indications. The active ingredients — Semaglutide vs Sitagliptin — share the same therapeutic approach, so many safety and management points carry across both.
Key differences
Meaningful differences are in active ingredient (Semaglutide vs Sitagliptin), strengths (0.25mg, 0.5mg, 1mg, 2mg vs 25mg, 50mg, 100mg), forms (pre-filled pen vs tablet), and the mechanism, half-life and side-effect nuances that distinguish members of the class.
Mechanism and action
Ozempic: After subcutaneous injection, semaglutide is absorbed slowly and binds to the GLP-1 receptor in pancreatic beta cells, alpha cells, central nervous system and gut. Januvia: Sitagliptin reversibly inhibits DPP-4, the enzyme responsible for rapid degradation of GLP-1 and GIP.
