A Cochrane review supports the use of high-dose vitamin B 12 (1 mg and 2 mg daily) in elevating serum vitamin B 12 level and achieving haematological and neurological responses, even in patients with PA or with ileal resection.58 The recommendation for oral replacement is 1 mg daily for a month, and then 125 to 250 g daily as maintenance dose for patients with dietary insufficiency and food-cobalamin malabsorption, while for PA the maintenance dose is 1 mg daily.29 Vitamin B 12 does not have side-effects even when prescribed in large doses.59 However, hypokalaemia, resulting from uptake of circulating potassium by newly growing and dividing haematopoietic cells, can be severe or sometimes life-threatening
Vitamin B12 shots can be quick and easy ways to correct a vitamin B12 deficiency, but like all injections, these shots do have the potential for certain drawbacks
Mixing is carried out under controlled conditions
For Ozempic, the highest dose is 2 mg weekly, while Wegovys highest doses are 1.7 mg or 2.4 mg once weekly
Since doctors think they need to keep levels within that range, they wont inject too often
