About Janumet XR

What is Janumet XR?

Janumet XR is a drug containing both sitagliptin (a DDP-4 inhibitor) and extended release metformin, a biguanide medication. These medications work together to control blood sugar levels. Sitagliptin works by increasing the release of insulin and decreasing the production of glucose in the liver. Metformin works by decreasing the production of glucose in the liver as well as decreasing the intestinal absorption of glucose.
