I have had an adverse reaction (felt nauseous and had to stay close to bed all day) after the B12 shot at the Dr surgery. I did not think any more of it until I happened to check the product I'd used. I had given them the ampoule from a new box sold to me by the chemist here in Australia. I checked the box and it is different from my normal product. Box says 'Hydroxo-B12 Injection Hydroxocobalamin (as chloride). My normal ingredient is Hydroxocobalamin (as acetate).
Does anyone have any experience or information about this Hydroxo' Chloride?
Obviously, I'll have to use it again to confirm my suspicions but I'm suspicious about this Aspen product.
