Due to the extraordinary ongoing circumstances of coronavirus, face to face appointments are only performed when essential for the health and safety of our staff and patients.
B12 injections have been classified as non-essential and will continue to be delayed until coronavirus has settled. The specialists advise that these have been shown to be equally as effective as the injectable form for most people. The recommended oral dose is 1000-2000mcg a day.
If this affects you, we understand that you may have concerns about this recommendation and so we have put together some questions and answers which may help reassure you.
Q) Why are you asking me to move from injection to tablets?
A) We have many patients with vitamin B12 deficiency registered at the practice who all need a face to face appointment at least every 3 months for their injections. The NHS is currently under tremendous pressure. NHS staff themselves are suffering from the virus and some staff at high risk are having to step back from seeing patients for their own safety. We are, therefore having to make some difficult decisions. The main reasons for the change are:
Many of the patients on B12 are themselves high risk and we do not want to put such patients at further risk by asking them to come and visit the practice.
We are trying to protect our own front line staff from unnecessary contact to help keep our essential services going
Moving to tablets frees up valuable time for our nurses to treat patients who absolutely must be seen in person and allows a little extra capacity if some of our nurses have to self-isolate.
Q) Will the tablets work as well?
A) There is evidence to say tablets work as well as injections if taken at the right dose (1000-2000mcg per day).
Q) I cannot absorb B12 so will the tablets work for me?
A) We cannot make B12 in our bodies; it has to be obtained from our diet. B12 mostly gets into our body because of a ‘carrier’ called intrinsic factor (IF). This IF binds to B12 and takes it into the blood. People can develop low levels of B12 because of a lack of IF or because they don’t take enough B12 in their diet. 95% of our B12 is carried into the body by IF. HOWEVER, there is another 5% which is absorbed without IF. If you take enough B12 (through supplements) then the body can manage to absorb enough B12 even if you do not have IF. We recommend you take a vitamin B12 supplement containing 1000-2000mcg per day. This is 400-800 times the normal recommended amount. This recommendation has come about because this is the dose that has been used in studies which have looked at the tablets versus injections for replacing low B12. There is no danger of overdose as the body will naturally dispose of excess B12 in urine.
Q) I have pernicious anaemia. Is it safe for me to switch to tablets?
A) Some people will have had a diagnosis of pernicious anaemia. The loading doses which everyone has to begin with have effectively treated the pernicious anaemia. The 3 monthly injections which follow are simply a precaution to stop the pernicious anaemia coming back through low B12 levels. As stated above, the tablets have been shown to be just as effective as the injections at treating low B12.
Q) What will happen once the concern about coronavirus passes?
A) We will get in touch with all the people affected by the suspension of B12 injections once the current pandemic has passed to invite them to consider how they wish to move forward. It may be that some people prefer to continue on tablets as they prefer not having to attend the surgery regularly for appointments and they prefer not having to have regular injections. It may be that some people would like some reassurance that their B12 level is OK on the tablets as opposed to the injections and we may consider doing some blood tests for reassurance. It may be that others prefer to go back onto injections.
If you have any further questions please feel free to contact the surgery. We would like to take this opportunity to thank you for your understanding of the huge strain that is being put on the health service at this challenging time.
