How does Bydureon BCise work?
Bydureon BCise works by mimicking the actions of a protein called GLP-1, which has a few functions:
- It causes your pancreas to release insulin when you eat a meal. Insulin lowers your blood sugar by helping your cells use blood sugar for energy or store it for later use.
- It also works to slow the speed at which your stomach and intestines digest food. This helps keep your blood sugar levels more consistent.
Bydureon BCise uses the above mechanisms of action to help lower your blood sugar. (A mechanism of action is the way a drug works in your body.)
If you have other questions about how Bydureon BCise works, talk with your doctor or pharmacist.

Bydureon BCise is used with a balanced diet and exercise to help manage blood sugar. It’s used in adults and children ages 10 years and older with type 2 diabetes.
With type 2 diabetes, you have blood sugar levels that stay higher than normal over a long time. This can cause problems throughout your body, including your eyes, kidneys, and feet.
Bydureon BCise works to lower blood sugar by causing your pancreas to release insulin. Insulin lowers your blood sugar by causing sugar in your blood to enter your body’s cells. It also works by slowing down how quickly your stomach and intestines digest food.*
Note: Bydureon BCise usually isn’t the first medication recommended to help manage blood sugar in people with type 2 diabetes. And it shouldn’t be used to treat type 1 diabetes.
