Januvia vs. Ozempic Drug Summary
Januvia
Januvia (sitagliptin) is a DPP-4 inhibitor used to control blood sugar in adults with type 2 diabetes, taken as a once-daily oral tablet alongside diet and exercise. It works by helping the body release more insulin after meals and lowering excess sugar production by the liver.

Ozempic (semaglutide) is a GLP-1 receptor agonist for blood sugar control in type 2 diabetes, given as a once-weekly subcutaneous injection alongside diet and exercise. It is also FDA-approved to reduce cardiovascular risk in patients with heart disease and to slow chronic kidney disease progression.
