subcutaneous or intra-muscle?

[caro43]

Hi, one more question. My Dr., prior to my diagnosis, told me to do methyl B12 shots subcutaneously. Should I continue that practice or do intramuscle instead? I have severe neuro involvement and have had it for almost a year and I suspect a B12 deficiency for atleast a decade.

General consensus seems to be - it makes little difference if you do IM or SC. If you're reading this on a full screen then there are 'Related Posts' over on the right, where this has been covered several times before.

Asked the B12 Deficiency charity b12d.org this and was told it doesn't really matter. You may need slightly more frequent injections as I believe it is stored for less time if you do sub-Q. They're working for me (too queasy to get into intramuscular injections I'm afraid).
