Eli99, with your injections are you taking folic acid as well as eating potassium rich foods, most doctors don't think of this but the B12 depletes your folate and you also need folate (folic acid) in order for your B12 injections to get to cell level. Are you on any facebook pages for this, I'm on a few and a particularly good one is Pernicious Anaemia/B12 Deficiency - Support Group, there are a few other good ones on there, if it wasn't for all the help I've had from these groups I wouldn't be where I am today health wise x

Hi
Welcome to the MedHelp forum!
The allergy can be to cobalt, any other component of injection, the oil base or even to the dye. Direct allergy to the vitamin itself is rare. You can discuss with the allergy specialist what this was exactly. If allergy was to cobalamin, then see if it is to cynocobalamin or hydroxycobalamin and try a formulation without it. There are Vit B12 preparations for sublingual route too. So probably you can try that too. Please discuss this with your doctor. If possible, seek another opinion.
Take care!
Hi. I recently had my first B12 injection for pernicious anemia. I did not have a rash afterwards, but my symptoms got much much worse. That's how I found your post, I was searching for possible allergic reactions to the shot.
Since, like you, I'm an info seeker and not a professional, I don't have any answers for you. But I do have some advice - drop that doc like a hot potato. Anyone who is actually concerned about your health - which a Dr should be after dx-ing pernicious anemia - would not have shrugged and ended treatment.
Just my 2 cents. But I got mad on your behalf when I read this. See someone else. You NEED B12 and if your body isn't getting it your condition will worsen.
