For ongoing care: 1 mL (1000 mcg) given as an intramuscular shot once a month
For mild deficiencies or maintenance, oral B12 supplements or tablets may sometimes be appropriate and can often be purchased elsewhere
Vitamin B12 is an essential nutrient, but injectable treatment still needs to fit the diagnosis, route, and monitoring plan
If you have a temporary deficiency or increased requirement (say, after a surgery or during recovery from an acute illness), you might only need a short course, perhaps a few weeks of injections, until your vitamin levels normalize or you can meet your needs by mouth again
[4] In case of accidental large overdose (e.g., someone receives far more frequent injections than prescribed), monitoring for symptoms like flushing, tingling in extremities, or liver enzyme elevations would be prudent
