Note on Expenses: These indicators represent gross infrastructure resource tracking paid directly to supply pharmacy networks by Medicare Part D configurations. These calculations do not track individual patient insurance tier copays or out-of-pocket shelf prices at retail checkout lanes.

Therapeutic Applications

Dulaglutide is used with a proper diet and exercise program to control high blood sugar in people with type 2 diabetes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. This medication is also used to lessen the risk of a major cardiovascular event (such as heart attack or stroke) in people who already have, or are at high risk for heart/blood vessel disease. Dulaglutide is similar to a natural hormone in your body (incretin). It works by causing insulin release in response to high blood sugar (such as after a meal) and by decreasing the amount of sugar your liver makes. Dulaglutide is not a substitute for insulin if you need insulin treatment.
