Vitamin B12 for injection - needle, syringe and antibacterial wipe included.How to Give Yourself a B12 Injection (SQ):• To prevent infection, wash your hands before giving a B12 shot. The skin is the body’s first defense against infection, so wash the injection site too (with an alcohol swab or soap). Wait until the area dries.• Draw B12 from the vial into your syringe of choice (for our B12 vials we like 0.3ml insulin syringes). You may need to push and pull the plunger back and forth a couple of times, in a pumping motion. Avoid touching the needle on the glass bottom of the vial, because it might dull its sharpness.• Hold the syringe upside down and check for trapped air. If you see an air bubble, flick the side of the syringe. You may need to flick it several times, until all air has risen to the top. Then push the plunger a little, just enough to push out the air.• Pinch the fat (to make sure you’re only penetrating subcutaneous tissue). Then thrust the needle in straight, as if you’re throwing a dart. Inject slowly.• When you give a B12 injection, it’s important to rotate the sites if you want to keep your skin healthy. Repeated shots in the same spot can cause scarring or hardening of fatty tissue, which may interfere with absorption. Keep injection sites 1in (2.5cm) apart from each other. And don’t inject to any swollen/burned spot.
