Should I ask my doctor for more regular Vitamin B12 injections?

I have been diagnosed with Vitamin B12 and Folate deficiency about 18 months ago. After initial boost of injections, I receive injections once every 12 weeks and take folic acid daily. 3/4 weeks after my injection I feel extremely tired and light headed again and its like my brain is made of cotton wool. I have memory loss, do strange things and would be very clumsy. Should I go back to my doctor and request more frequent injections?

Yes! Also ask for your ferritin, vit D and thyroid to be tested. How much folic acid do you take?


They prefer to give them every 12 weeks. However, if you are experiencing symptoms e.g. stinging tongue, bed sweats, headaches etc then the nurse can give the injection after 8 weeks from your last injection, this is the most regular they will go, I think. Also, I don't think they can do it every 8 weeks for long-term, it is only if your symptoms get bad.


My doctors give them to me every 4 weeks as I get numbness and pins and needles in my hands if not. It was a prescribing nurse that suggested it. I think if you have neuro symptoms they are more likely to give you more jabs.
