Does anyone have any information on allergy to B12.

I'd also like to hear from anyone with an allergy to B12 injections. After having them for over 15 years I'm now experiencing some serious reactions each time I have an injection. It's happened 5 times now and the last time was in hospital after being given a drip of cortisone mixture to prevent the reaction but it didn't work too well. I'm now very anxious to hear from anyone with similar experiences. I've tried both types of B12 serums and now waiting for the specialists to come up with a solution.

There are doctors at Guys Hospital in London who will treat B12 allergy. Have you seen an allergist..have you had skin tests for cobalt. If you need the names of the doctors, contact the pernicious anaemia society.
