What does it do?

How does it work?

Exanatide is a synthetic protein that mimics the action of a GLP-1, a natural hormone involved in regulating blood sugar levels.

Exanatide:

• Increases secretion of insulin from the pancreas in response to high blood sugar levels
• Slows emptying of the stomach, preventing steep rises in blood sugar after meals

 

How should it be used?

• Unused injection pens should be refrigerated, but stored at room temperature after first use
• If you experience symptoms of low blood sugar, eat or drink something sugary

10–20mcg daily, injected 2 x daily, each dose at least 6 hours apart

When should I stop using it?

Is it safe for prolonged use?

No problems expected, but diabetics need regular monitoring of sugar levels, kidney function, eyes and the heart.
