I would encourage patients to speak to their practice if they have concerns about their B12 treatment
B12 should be kept out of the reach of children
Since your body naturally does not make vitamin B12 on its own, you will have to take it from another source like animal-based foods, pill supplements, or injections
Some doctors may even prescribe B12 injections to prevent deficiencies before they start (especially if your bloodwork's numbers are on the low side).If you suffer from anemia or a B12 deficiency, you may need B12 as a treatment
Some patients feel as though they want more frequent injections, and occasionally we test levels to see if they are receiving adequate replacement, but Im not sure how strong the evidence is to support this. GPs should consider periodic vitamin B12 testing of higher-risk patients who take metformin, even if they dont display symptoms of deficiency, the UK medicines regulator said earlier this year
