After you have put the insulin cartridge in the insulin pen, screw on a new needle.

Remove the outer cap from the needle. Keep this outer cap. You will use it later to safely dispose of the needle.

Remove the inner cover from the needle. Be careful not to prick yourself. To keep the needle clean, set the insulin pen on a counter or put the outer cap back over the needle while you do the next step.

Clean the area of skin where you will give the injection. If you use alcohol to clean the skin, let it dry.

If you covered the needle with the outer cap, remove it now. Then, using the hand not holding the insulin pen, slightly pinch a fold of skin between your fingers and thumb.

Push the needle all the way into the pinched-up area.

Let go of the pinched-up area, and push the plunger of the pen all the way in. Count to five before taking the needle out.

Put only the outer cap back over the needle. The thin, inner cover is harder to put back on and you may stick yourself.

After covering the needle with the outer cap, unscrew the needle and throw it away in a sharps container or other solid plastic container. You can get a sharps container at your pharmacy.
