I'm still struggling to get my injection frequency right. I live in Portugal and I'm having Neurobion injections that contain 1mg cyanocobalamin plus B1 and B6. I had a loading dose and now I'm on monthly injections. However, the package leaflet says the follow-up dose should be 2-3 ampoules per week after the loading dose.
My latest blood test shows I'm back within normal range just about. Despite this, I get symptoms returning about two weeks after each monthly injection (pins and needles, difficulty concentrating, very low energy, palpitations, unexplained aches and pains). I'm trying to stick to monthly injections, but sometimes I only make it to three weeks before I cave in and get another one.
I'm going to be switching to a 10mg cobamamide formulation soon, that my doctor reckons I'll only need every two months.
Any thoughts, experience, advice?
