Pharmacist Tips:

– Non-drug management, including diet and exercise, also plays an important role in controlling diabetes.
– If you use insulin in addition to Exenatide, do not mix them into the same syringe. You may give the shots in the same area (including your stomach), but do not give the shots right next to each other.
– Change (rotate) your injection site with each weekly injection. Do not use the same site for each injection.
– Do not share pens between patients.
– Store your new, unused medicine pen in its original carton in the refrigerator. You may store the opened medicine pen in the refrigerator or at room temperature for 30 days. 

For Pen:
Allow the pen to come to room temperature (wait at least 15 minutes after removal from refrigerator) prior to administration. Hold the pen by the end with the orange label and tap firmly against the palm of hand to mix until suspension is evenly mixed with no residual medicine along the top, side, or bottom. The mixture should appear uniformly white to off-white or cloudy, then administer immediately after mixing. To ensure a full dose is delivered, after insertion of the needle press the injection button until it clicks and holds for 10 seconds.

For auto-injector:
Allow the auto-injector to come to room temperature (wait at least 15 minutes after removal from refrigerator) prior to administration. Shake the autoinjector vigorously for at least 15 seconds until suspension is evenly mixed with no residual medicine along the top, side, or bottom. The mixture should appear uniformly white to off-white or cloudy, administer immediately after mixing. To ensure a full dose is delivered, press the auto-injector against skin until it clicks and hold for 15 seconds.

Common dosing schedule:
Exenatide can be injected subcutaneously in the abdomen, thigh or upper arm. You may administer at any time of day, independently of meals. 

This schedule is for reference only, adjustments may be made according to individual needs.
