Prepare a home treatment area on a clean counter of your home or space. You will need:  Prescribed vitamin B12 solution. A covered clean needle and syringe. Cotton balls. Rubbing alcohol. Small band aids. A puncture-proof container to dispose of the used needle. Make sure the chosen injection site is uncovered and the person’s bare skin is exposed. Then, dip a cotton ball in the rubbing alcohol. Clean the person’s skin using the cotton ball in a circular motion. Allow the site to dry. Use a new cotton ball, dipped in rubbing alcohol, to wipe the surface of the container with the B12 solution. Let this dry. Remove the clean needle from the package and take off the safety cover on the needle. Then, insert it into the vial. Push the air out of the syringe by pushing the plunger, and then slowly pull back on the plunger, until the syringe fills to the required amount. Tap the syringe lightly with your finger to remove any air bubbles in the syringe. Give a slight push on the syringe to dispel a tiny amount of the vitamin B12 supplement to ensure the air is out of the syringe. Use the thumb and forefinger of your free hand to hold the skin of the injection site taunt. No matter where the chosen injection is located on the person’s body, the skin should be smooth and tight to make it easier to administer the supplement.  Let the person know you are going to inject the supplement. Then, inject the needle into their skin at a right angle. Hold the needle steady and push down the plunger slowly until all of the supplement is inserted. Once the needle is inserted, pull the plunger back a little to check that there is no blood in the syringe. If there is no blood, inject the supplement.  Try to inject into relaxed muscles. If the person appears nervous or tense, tell them to keep their weight on the leg or arm you are not injecting into. This will help them keep the muscles by the injection site relaxed.  If you are injecting the vitamin B12 into yourself, use your free hand to hold the skin of the injection site taunt. Relax your muscles and inject the needle at a right angle. Check that there is no blood in the syringe and then inject the rest of the supplement if there is no blood. Make sure you remove it at the same angle of insertion. Use a cotton ball to stop any bleeding and to clean the injection site.  Wipe the injection site in a circular motion. Apply a band-aid to the site to keep the area protected. Do not throw used needles into your regular garbage. You can ask your doctor or pharmacist for a puncture proof disposal container, such as a sharps container, or make your own container.  Use a metal coffee can and duct tape the lid on to it. Cut a slit in the lid that is wide enough for needles to fit through. Label the can so you know it contains needles. As another option, use a thick plastic detergent bottle to store your used needles. Keep the lid on the container at all times so the needles don't fall out. Make sure this container is labeled to reflect that it is now full of used needles, not detergent.  When the can is 3/4 full, take it to your doctor’s office, a bio-hazard collection site, a hazardous waste center, or a syringe exchange program for disposal. As another option, consider enrolling in a residential "special waste" program that will come pick up your needles. Never use the same needle twice, as this can lead to infection or illness. You can store any unused vitamin B12 injections at room temperature, away from moisture, heat, and light.
