What is Sitagliptin?
Sitagliptin is a prescription medication used to manage type 2 diabetes mellitus. It belongs to a class of drugs called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors), which help control blood sugar levels in adults.
It is commonly used along with diet and exercise to improve long-term glucose control.

It is most effective when combined with a healthy diet and regular physical activity.
