How Januvia (sitagliptin) works
Januvia (sitagliptin) is a dipeptidyl peptidase-4 (DPP-4) inhibitor. It blocks a protein in the body called DPP-4 from working. This helps insulin stick around in your body longer. It also stops your body from making glucagon, a hormone that raises blood sugar. Together, this helps control your blood sugar levels.
