Make sure you have some alcohol swipes and clean the top of the vial of B12. If you do not have these, use a little swatch of bandage and alcohol to clean it. Also clean the area on your buttocks. I always used the area on the right buttock about mid to upper area because I am right handed.
Pull the plunger back on the syringe to the ordered dosage. Uncap the syringe needle and push it through the rubber top on the vial. Deposit the air into the vial of medicine by pushing down on the plunger. While the needle remains in the vial of B12, pull the ordered dose of medicine into the syringe by pulling the plunger back. Remove needle from the bottle, recap it and put it aside.
This may sound scary but it’s not. I used to worry about getting air in my needle but it’s just like in the movies, you push on the plunger, squirting some of the medicine out to remove any air in case you want to be extra safe. Although, the way you do it in the first paragraph is sufficient.
Now here is the tricky part…picture the area on your behind as a target. You want to move fast so it doesn’t hurt. Stab that part of your butt with the needle and press the plunger slow to inject the B12. You don’t want to push it too fast or it’ll burn. Just nice and slow. Then remove the needle fast and you’re done.
If you are unsure of where to place the injection you can try this - A common injection site for intramuscular shots, such as vitamin B12, is in the dorsogluteal muscle. Draw an imaginary cross on the buttocks cheek and aim for the upper outer corner.
