Ask a Doctor and Get an Answer to Your Medical Question ASAP
Hi. Welcome to JustAnswer. I shall try my best to assist you while you are corresponding with me.
There are a lot of replacement regimens available for vitamin B 12 and much depends on what your physician is comfortable with and what you can comply with as well.
Personally, I would have tested your vitamin B 12 levels before starting you on replacement therapy and given a loading dose as well.
You should discuss this with your GP as 3 monthly injections are maintenance rather than replacement shots and maintenance can only be done once the lost stores have been replenished.

I do not understand what you mean my B12 has been tested that is why I got my 1st injection I want to know because, I had been without B12 for nearly 4 years and should I have a booster, when you have pernicious anaemia I was told it had to be for life and I have been poorly for a long time simply because I was taken off it
Sorry I am not satisfied with your answer it did not help at all
Hi, my apologies if I wasn't clear in my answer, let me be more elaborate.
Yes, what I meant was that before starting any replacement whether it is a hormone or a mineral or vitamin, obtaining a baseline level of the deficient component is beneficial. As it gives an idea of how much and how rapidly to replace it. Also, it gives a reference value to which one can compare after a while to see if the replacement is having an effect. In pernicious anemia, the replacement is for life and yes, I think you should have a booster and then be put on maintenance.
