What is metformin and saxagliptin (Kombiglyze XR)?

Metformin and saxagliptin are oral diabetes medicines that help control blood sugar levels. Metformin works by decreasing glucose (sugar) production in the liver and decreasing absorption of glucose by the intestines. Saxagliptin works by regulating the levels of insulin your body produces after eating.

The combination of metformin and saxagliptin is used to treat type 2 diabetes. This medication is not for treating type 1 diabetes.

Metformin and saxagliptin may also be used for purposes not listed in this medication guide.
