My mum has B12 injections every 3 months following an ileostomy. She used to be full of energy after each one but since changing GP practice 6 or 7 years ago she no longer feels the benefit. Are there different formulas that could cause this? I keep asking her to get printouts of her blood tests but she never does.
She now has to take her prescription to the chemist rather than the GP get it directly. Is there a better brand / type?
