Practical Issues (including administration)
- Product will ship as a solid, which requires refrigeration. May store for up to 90 days in its unopened original packaging at room temperature.
- Must be left at room temperature for 30 minutes prior to injection.
- The prefilled syringe needs to be flicked with a forceful downward whipping motion of your full arm to move the bubble to the cap of the syringe. Standing while flicking may help achieve the required force. The bubble will appear opaque.Ā Ā Holding the syringe up to a light or against a dark backdrop may improve visibility.Ā Ā If the bubble is not in the cap, it could result in incomplete dosage administration.
- Must be administered in the abdomen or upper arm as a subcutaneous injection.
