Sitagliptin is an oral diabetes medicine that helps control blood sugar levels. It works by
regulating the levels of insulin your body produces after eating.
Sitagliptin is for people with type 2 diabetes (non-insulin-dependent) diabetes. Sitagliptin is
sometimes used in combination with other diabetes medications, but is not for treating type 1 diabetes.
Sitagliptin may also be used for other purposes not listed in this medication guide.
