You first need to wash your hands. You then wash the area you are going to inject with an alcohol swab. Wipe off the top of the vial of the solution that you are going to inject. Remove the cap of the needle without touching the end of the needle. Put the needle into the vial and turn the vial upside down and draw the amount you need out. Take the needle out and tap it if there are any air bubbles to remove them. Insert the needle into the area and slowly push the fluid into the area. Pull the needle out once all the fluid is out of the syringe.
