Preparing the DAWNZERA autoinjector.

If your autoinjector is in the fridge, remove it. Keep the autoinjector in the original carton and let it come to room temperature for 30 minutes before injecting.



The medicine should be clear and colorless to yellow. There should be no particles. It is normal to see air bubbles in the solution.

Demonstration of cleaning the injection site.

Choose an injection site on the stomach or the front of the thigh. If a caregiver is helping you, the back of the upper arm can also be chosen.

Wash your hands with soap and water. Clean the injection site with an alcohol wipe in a circular motion. Let the skin air dry. 



Do not touch the cleaned skin before injecting.

Demonstration of injecting DAWNZERA.

Remove and throw away the clear cap. Place the orange needle shield at a 90-degree angle against your skin. Push firmly and hold the autoinjector straight against the skin. You will hear a click as the injection starts.

You may hear a second click. This is normal. The procedure is not finished.



Hold the autoinjector against the skin for 10 seconds to make sure the full dose has been given. Remove the autoinjector by lifting it straight up. 



Put the used autoinjector in a sharps container after use.
