How To Get Rid Of Heart Palpitations Due To Missed B12 Medicines?

My dr. Told me to take 1,000 mcg of B12 eight months ago. My blood level went from 212 to 906 . She never asked to check it and three weeks ago I stopped for two days and then had heart palpitations. Since then my heart is racing, I can't sleep both at that dosage. I can't seem to stabilize or get off it.

Hi

Firstly your B12 level of 906 is in the normal range and you have been cured of macrocytic anemia, which is a good thing.

Stopping B12 is very unlikely to cause any change in the heart rate as B12 does not have any direct effects on the cardiovascular system.

I suspect there could be some other cause for your palpitations. Are you sure you are not having any other reason for the anxiety as such?

What is the pulse rate like? I suggest you get examined by your GP if it is bothering you too much to cause loss of sleep even after 1 week.
