From the Guidelines
I strongly recommend seeking vitamin B12 shots at a medical clinic in the Montjuic area of Barcelona, with the initial dose and frequency determined by a healthcare professional based on the presence of neurological involvement and the severity of the deficiency, as outlined in the British Obesity and Metabolic Surgery Society guidelines 1. To receive a B12 shot, you should first consult with a doctor who will determine if you have a deficiency through blood tests.
- The doctor will assess the severity of the deficiency and the presence of neurological involvement, such as unexplained sensory and/or motor and gait symptoms.
- If neurological involvement is present, hydroxocobalamin 1 mg intramuscularly should be administered on alternate days until there is no further improvement, then hydroxocobalamin 1 mg intramuscularly administered every 2 months 1.
- If there is no neurological involvement, hydroxocobalamin 1 mg intramuscularly should be administered three times a week for 2 weeks, followed by maintenance treatment with 1 mg intramuscularly every 2–3 months for life 1. Vitamin B12 injections are particularly beneficial for those with absorption issues (like pernicious anemia, celiac disease, or after certain surgeries) as they bypass the digestive system.
- Side effects are generally minimal but may include pain at the injection site or rarely, allergic reactions. It is essential to seek urgent specialist advice from a neurologist and haematologist if there is possible neurological involvement 1.
From the FDA Drug Label
INDICATIONS AND USAGE Cyanocobalamin is indicated for vitamin B12 deficiencies due to malabsorption The Vitamin B12 shot, also known as Cyanocobalamin (IM), is indicated for vitamin B12 deficiencies due to malabsorption, which may be associated with certain conditions.
- The shot is used to treat vitamin B12 deficiencies, but Montjuic is not mentioned in the drug label. 2
From the Research
Vitamin B12 Shot Montjuic
- The provided studies do not specifically mention "Vitamin B12 shot Montjuic", however, they do discuss Vitamin B12 deficiency, its diagnosis, and treatment.
- Vitamin B12 deficiency can be caused by malabsorption, defects in cellular delivery and uptake, and limited dietary intake 3.
- The diagnosis of Vitamin B12 deficiency rests on clinical suspicion followed by laboratory testing, which consists of a panel of tests, including serum B12, holotranscobalamin, methylmalonic acid, and homocysteine measurements 4, 5, 6, 7.
- These biomarkers have their limitations and the sensitivity and specificity of each biomarker for the evaluation of B12 status is affected by analytical and biological factors 5.
- A combination of a B12 and a metabolic marker, for example, total B12 and methylmalonic acid, may prove most useful in daily practice 7.
- The consequences and severity of B12 deficiency are variable depending on the degree of deficiency and its duration, and major organ systems affected include the blood, bone marrow, and nervous system 3.
