Gather your supplies: This will typically include your pre-filled injection pen and an alcohol pad.

Clean your hands thoroughly with soap and warm water.

Choose your injection site. This can be your abdomen (around your belly button but not the 2-inch area directly around it), thigh, or upper arm.

Clean the injection site with an alcohol wipe and let it air dry.

Remove the cap from the pen to reveal the pre-attached needle.

Pinch the skin at the injection site.

Hold the pen like a dart, and insert the needle into the pinched skin at a 90 degree angle.

Press the injection button at the end of the pen until it stops moving and hold it for the recommended time (usually about 5-10 seconds) to make sure the full dose is administered.

Lift the pen straight out without sliding it along your skin.

Recap the pen without touching the needle. The needle is for single use and should not be reused.

Store the pen as directed. Do not store it with the needle attached.

Apply a band-aid to the injection site if necessary.

Monitor the site for any signs of redness, swelling, or infection.

If you experience any adverse reactions, such as nausea, vomiting, rapid heartbeat, or difficulty breathing, seek medical attention immediately.
