The route of b12 shots is suggested according to the patient symptoms as all the three routes differ in their bioavailability and thus efficacy. For slow and steady continuous release, b-12 shots are given through subcutaneous route whereas intramuscular and intravenous route are used for rapid availability of b12 in the circulation, for rapid relief from symptoms.
B12 shots are recommended for many purposes such as b12 deficiency, as an energy booster and weight loss purposes. The secret behind freshness and never ending energy of most of the celebrities seen on media is b-12 shots. With an increase in the trend of b12 shots, people prefer to self -administer the injection instead of going to the hospital every time. B12 deficiency is very common because of the too rare sources of this essential nutrient. It is one of the eight water soluble vitamins and for b-12 shots it is produced by the fermentation of bacteria and yeast. Naturally occurring sources rich in vitamin b12 are only lambs liver and meat whereas vegetables are very poor in it. There are many routes for b12 administration such as nasal spray for mucosal absorption and subcutaneous, intramuscular and intravenous b-12 shots.
You can either self -administer b12 shots or someone else such as a nurse or doctor can do it for you. For proper administration of b-12 shots, the technique should be followed carefully. The route of b12 shots is suggested according to the patient symptoms as all the three routes differ in their bioavailability and thus efficacy. For slow and steady continuous release, b-12 shots are given through subcutaneous route whereas intramuscular and intravenous route are used for rapid availability of b12 in the circulation, for rapid relief from symptoms. The most complex of the three routes for b12 shots is the intravenous route. As more care and vigilance is required during the administration of intravenous injection, it is difficult to self-inject b-12 shots through this route as compared to intramuscular and subcutaneous routes. B12 shots can also be administered through IV infusion for which 2.5g of b12 available as hydoxocobalamin is reconstituted with 100 ml of 0.9% sodium chloride solution, lactated ringers solution or 5% dextrose. B-12 shots are given via infusion if intensive therapy is required for extreme deficiency of vitamin b12. It is given at a steady rate of 5g during initial 15 minutes followed by another 5g after hrs.
The pre-requisites for b12 shots are; a syringe, pair of surgical gloves, b12 vial, tourniquet, alcohol swab and a bandage. Take a shower with an anti-septic soap or shower gel before getting b-12 shots, to clear germs from the injection site. Intravenous b12 shots can be given in veins of hands, wrist, arm, legs, feet, groin and neck. Veins of dorsal side of hand and ventral sides of wrist and arm are the most common sites whereas the rest are only used if these cannot be used or approached easily. For example if you want to self –inject b12 shots, then legs and feet are easier to inject in, whereas if someone else is giving the shot then arms and hands can be used easily.
