6. Hold the syringe in the hand you write with, and with the needle pointing down. With your other hand, gently pinch the selected area of your abdomen between your thumb and forefinger to create a fold of skin. Be sure to hold the skin fold throughout the injection.

Vertically insert the full length of the needle (at a 90o angle) into the skin fold.

7. Press down on the plunger with your thumb or finger. This will deliver the medication into the fatty tissue of your abdomen. Be sure to hold the skin fold throughout the injection.
