Injections Stopped by GP

Was diagnosed with PA 2 years ago and been on injections every 3 months since then. Was due for my next injection last Wednesday - about 15 minutes before I was due to leave the house I got a call from the nurse to advise that my appointment was cancelled as my levels were too high following a blood test I had the month before (testing for various things as I'm feeling completely exhausted all the time).

I tried explaining that injections shouldn't be stopped and that levels would be high due to treatment, but I was advised that the senior GP at the surgery wouldn't sanction it and that i was to go back in 6 months to be tested again. I was told that if I had an issue with this then I need to make an appointment to see this GP - which I've done and the earliest appointment is now another 2.5 weeks away.

Feeling so frustrated - I'm too tired to have a battle with them. Just needed to have a bit of a rant 😀

😀, you are entitled to rant Simba01,

Maybe you could take someone with you to your Appointment, And, go with printed info for your GP.

Members will point you in the right direction regarding which print outs are used in cases like yours.

It's frustrating, but you are in the right place for getting help.

If you are in UK, I'd suggest contacting PAS (Pernicious Anaemia society) as soon as possible. They have experience of helping members with PA who have had injections stopped.



PAS tel no +44 (0)1656 769 717 answerphone so messages can be left, may take a couple of days to get a response.

PAS membership


There are stories of how PAS helps people on Martyn Hooper's blog.




"I tried explaining that injections shouldn't be stopped"

Have you considered writing a letter to GP outlining concerns?

If you write a letter I would suggest keeping a copy for yourself.

My understanding is that letters to GP have to be filed with medical records so are proof that an issue has been raised.

Writing to GP about B12 deficiency


Person who runs this website can be contacted by e-mail. She is helpful and sympathetic.

Proof of PA diagnosis

Do you have proof that you were diagnosed with PA eg copy of letter from GP, positive result in Intrinsic Factor Antibody (IFA) test?

May be worth getting copies of blood test results and other medical records. Some people on forum who have had injections stopped have found it hard to prove they had a previous PA diagnosis.

Access to medical records



Consequences of stopping B12 injections

Stopping injections in people who have a definite diagnosis of PA is potentially putting them at risk of neurological damage.

Some people on forum have showed their GPs information on SACDSC "sub acute combined degeneration of the spinal cord" as an example of what can happen if B12 deficiency is not treated. there is an article on SACDSC in PAS library section on website.


UK b12 documents/articles that specify lifelong treatment for PA

1) BSH Cobalamin and Folate guidelines


Treatment info is about a quarter through document.

2) BNF Chapter 9 Section 1.2

All UK GPs will have access to BNF. There is probably a copy on GPs desk or bookshelf .


Unhappy with treatment (UK)



HDA patient care trust

Uk charity that offers free second opinions on medical diagnoses and treatment.


B12 books

I gave my GPs a copy of "What You Need to Know About Pernicious Anaemia and Vitamin B12 Deficiency" by Martyn Hooper which mentions lifelong treatment for PA.

I am not a medic just a perosn who has struggled to get a diagnosis.


If you have P.A. injections are for life and they are putting your life in jeopardy by refusing treatment.

You really must make them listen and look at the following


Half way down the page under "What is the treatment for B12 Deficiency" it plainly states:

"If you have pernicious anaemia the injections are needed for life. Apart from the discomfort of having an injection, you should have no side-effects from the treatment. The injections are simply replacing a vitamin that you need".

I was told that without the injections I had only two years to live = 45 years later I'm still "clivealive" at 75


It's disgraceful, doctors who can't read, don't read, won't read. I'm forever ranting too.

That's good advice, take a friend, (preferably a 6'5" ex-boxer) and the relevant guidelines, given by Sleepybunny , highlighted in yellow marker. "Treatment for PA is . . . . for life, no further testing necessary.


Thanks all, really appreciate the replies. Will make sure I go armed with printed info for my appointment and will also follow up with the PA Society. Sadly, I don't know any 6'5 boxers, but I've got 17 days to find one!!


Good luck

Hope you find someone to go with you. Doctors are sometimes kinder when another person is present. Do you have someone who can go with you, preferably someone who has also read up about b12 deficiency ?

As I suggested above, may be worth putting concerns in a polite letter as things said in consultation get forgotten and sadly GPs don't always read what they are given by patients.

If you forget to take guidelines with you at next appt, the GP will have a copy of BNF (British National Formulary) in room and may be willing to let you look at that. Info about B12 treatment is in Chapter 9 Section 1.2

"that levels would be high due to treatment, "

In BSH Cobalamin and Folate guidelines it makes it clear that testing after B12 treatment has started is irrelevant. Think fbirder 's summary of mainly UK B12 documents mentions something about this. Link to his summary in third pinned post.

BMJ B12 article



Hi Simba01

I would suggest you write a letter to you gp stating you are very concerned a bout your physical and mental wellbeing because your B12 injections have been withdrawn in error and include copies of guidelines recommendations re: treatment of PA and neurological symptoms highlighting these. Do make sure gp gets this letter before your appointment and take extra copies with you when you go and do take a witness with you.

You have been given excellent advice already by several members of the forum. Do make sure you contact PAS in Wales.

Good luck and let us know how you get on.


Well I would ask what is classed as too high?

i need at least level of 1000 to feel functional.Mine is normally way over 1000

I used vegan b12 vegan sublingual from Global Health then i had more control over my own health

Request what the level was and keep a diary so you know what level works for you.

Good luck
