Is this article why some of us are being put on oral b12? what do we say to this?
This is what is says
This study confirms that oral 1000 μg cyanocobalamin provides effective maintenance therapy for vitamin B12 deficiency of all causes. General practitioners can be confident that this alternative treatment is both safe and effective in the long term—ongoing monitoring of our patients has substantiated that belief.
An oral treatment can produce substantial savings by removing the necessity for nurse involvement either at home or at the surgery for injection therapy.14
Patients much prefer oral medication and given the opportunity to choose between an injection and a tablet of vitamin B12, clearly demonstrated this preference. Vitamin B12 replacement therapy is ideally suited to a standard monitoring protocol and this should become a regular part of our care.
Patients with the very rare condition of tobacco amblyopia should remain on hydroxocobalamin as there is a theoretical possibility of cyanocobalamin (rather than hydroxocobalamin) increasing the risks of this condition.15
There is now an oral alternative4 to a parenteral treatment and oral vitamin B12 is now a therapy option. The study confirms oral vitamin B12 is effective and acceptable as maintenance therapy in UK general practice for which we advocate its use. “Medicine’s best kept secret”4 is certainly out and the time for change has arrived.Learning points
Oral vitamin B12 is effective in the treatment of vitamin B12 deficiency including pernicious anaemia but is rarely used for this indication in the UK.
The 1000 μg tablet of cyanocobalamin used in this study is safe to use for maintenance therapy in UK general practice.
Patients prefer oral medication to an injection of vitamin B12.
The burden of work undertaken by community nurses and general practitioners in administering injectable vitamin B12 can be substantially reduced.
We need to look at our current practice and move forward with oral vitamin B12 replacement therapy.
