Are air bubbles in the Trulicity® (dulaglutide) pen normal?

Air bubbles in the dulaglutide pen are normal. They will not cause harm or affect the dose.


Small air bubbles and subcutaneous injection

Dulaglutide should be injected subcutaneously under the skin into the fat tissue layer (subcutaneous injection).1

Small air bubbles are not a problem in this type of injection.2

Injecting air bubbles is more of a safety concern when medicines need to be injected into a vein (intravenous administration).2
