Januvia is a brand-name prescription diabetes medication that controls blood sugar levels. Its active ingredient is sitagliptin, a drug classified as a DPP-4 inhibitor. Drugs like sitagliptin increase insulin concentrations in the blood after a meal and decrease the body’s production of a blood glucose-raising hormone during the rest of the day. Januvia may be prescribed alone or with other diabetes medications, and is taken once daily as a tablet.
