Pregnancy advice

I am currently 25weeks pregnant after a couple of years of trying. I was diagnosed with PA about 10 years ago via part 1 and 2 of the schilling test. No intinsic factor antibodies, more a lack of intrinsic factor.

Anyway I have carried on with my monthly injections of cyanocobalamin as advised by my GP, 1mg monthly. I do not tolerate hydroxocobalamin well - acne and itching,

Can you breast feed on cyanocobalamin?

  • I am not sure but I don't think it is recommended in relation to making sure that your baby gets all the B12 they need. Other nutrients etc shouldn't be affected - so you can and should breast feed but will also need to provide some supplementation.

    Have you discussed this with your GP/mid-wife?

    If you are a member of the PAS (who sponsor this forum) then they have a dedicated nurse who can advise


  • The BNF says this about injectable B12:

    Breast feeding:

    Present in milk but not known to be harmful.
