2 mg powder and solvent for solution for injection , prolonged- release suspension 

1. What Bydureon is and what it is used for

Bydureon contains the active substance exenatide. It is a drug to be injected and used to improve blood sugar control in adults with type 2 diabetes mellitus.

This medicine is used in combination with the following diabetes medicines: metformin, sulphonylureas, thiazolidinediones, SGLT2 inhibitors, and/or long-acting insulin. You are now being prescribed this medicine as a supplement, in order to better control your blood sugar level. Continue to follow the diet and exercise program you have received.

You have diabetes because your body does not produce enough insulin to control your blood sugar level or because your body cannot use insulin properly. This drug helps your body increase insulin production when blood sugar levels are high.
