My endo has written me a private prescription for B12 to inject - I don't have PA as far as I know but am hypothyroid with a variety of digestive problems and find it difficult to tolerate oral supplements. She has prescribed 1mg every other day x 3 doses, so I don't know what I'm supposed to do after that - I think it's just to see how I get on with it, although I don't expect to notice much difference on three doses.
I've rung round the local dispensing chemists and all that they seem to offer is cyanocobalamin. As the prescription for 3 ampoules from the chemist is going to cost more than it would to get cyanocobalamin from the 2 UK internet sites that I know of, I'm not sure what to do. I would rather get it on prescription because at least I can be sure of what I'm getting, but also I thought that hydroxcobabalmin was the preferred type for injection - (and methylcobalamin for oral use) - and no dispensing chemist seems to offer that.
I did find an internet site that offered 1mg ampoules of hydroxocobalamin, but it came from all manner of parts of the world, and without wishing to sound bad, I'm a bit worried about ordering it, let alone injecting it.
Could somebody please tell me what is so bad about cyanocobalamin - apart from the obvious 'cyanide' connotation? If anybody knows of a reputable source of hydroxocobalamin, perhaps they would be kind enough to pm me?
I believe the PA Society has a doctor they recommend, but at the moment I am not well enough to travel long distances to consult anybody. I would be very grateful for any advice. Thank you.
