What is exenatide?

Exenatide is an injectable diabetes medicine that helps control blood sugar levels. This medication helps your pancreas produce insulin more efficiently.

Exenatide is used to treat type 2 (non-insulin dependent) diabetes. Other diabetes medicines are sometimes used in combination with exenatide if needed.

Exenatide may also be used for other purposes not listed in this medication guide.

Precautions

Do not use exenatide to treat type 1 (insulin-dependent) diabetes, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).

If you have any of these other conditions, you may need a dose adjustment or special tests to safely use this medication:

  • kidney disease (or if you are on dialysis);
  • problems with digestion; or
  • severe stomach disorders (gastroparesis).

FDA pregnancy category C. It is not known whether exenatide is harmful to an unborn baby. Before using exenatide, Tell your doctor if you are pregnant or if you become pregnant during treatment.

It is not known whether exenatide passes into breast milk or if it could be harmful to a nursing baby. Do not take exenatide without telling your doctor if you are breast-feeding a baby.

Avoid drinking alcohol. It lowers blood sugar and may interfere with your diabetes treatment.

If you are using any type of antibiotic or birth control pill, take these medicines at least 1 hour before you use exenatide.
