Overview
Janumet is a prescription drug approved by the Food and Drug Administration (FDA) to help improve blood glucose control in adults with type 2 diabetes. Janumet is considered an adjunct treatment to diet and exercise.

Janumet is a combination drug composed of the drugs Sitagliptin, the active ingredient in Januvia, and Metformin. Sitagliptin is a dipeptidyl peptidase 4 (DPP-4) inhibitor. Sitagliptin is believed to work by lowering blood glucose levels when they are elevated. Metformin is a biguanide. Metformin is believed to work by decreasing the amount of glucose produced by the liver and making the muscle tissue more sensitive to insulin.

How do I take it?
Prescribing information states that Janumet is generally taken twice daily with meals.

Janumet comes in tablet form.
