Overview: Jentadueto is taken to lower blood sugar in people who have type 2 diabetes. Jentadueto increases your insulin levels, especially after you eat. It also reduces the amount of sugar you absorb from things you eat and drink. Common side effects include diarrhea and symptoms of the common cold. Notify your healthcare provider if you have severe or frequent episodes of low blood sugar.

Uses

What is Jentadueto used for?

Jentadueto (linagliptin/metformin) is used to help lower blood glucose (sugar) levels in people with type 2 diabetes.

Jentadueto may also be used for other conditions as determined by your healthcare provider.

How does Jentadueto work (mechanism of action)?

Jentadueto works in several ways to help keep your blood sugar levels from getting too high. It increases the levels of natural hormones in your body to lower blood sugar by increasing insulin levels, especially after meals. (Insulin is a hormone that helps your body use sugar as a source of energy.) Jentadueto also decreases the amount of sugar your body absorbs from things you eat and drink, reduces the amount of sugar that your liver makes, and helps your body’s own insulin work better.
