The dosing regimen varies depending on whether neurological symptoms are present: With neurological involvement: 1 mg intramuscularly on alternate days until no further improvement, then 1 mg every 2 months [3] [4] Without neurological involvement: 1 mg intramuscularly three times a week for 2 weeks, then 1 mg every 2-3 months for maintenance [3] [4] There is some evidence that high-dose oral B12 (1000-2000 micrograms daily) may be effective even in some malabsorption conditions, though UK practice still generally favours intramuscular treatment in these cases
Dosing: Start 0.75 mg SC once weekly at any time of day, with or without meals
