Allergic to synthetic thyroxine, what do you think Sheila?

[Guest guest]

Hi, Can you tell me Sheila, the answer to this question. I have now been joint

pain free for quite a few months since being on Erfa, before this time I was in

extreme pain in my joints, I went to the G.P. who did a blood test which

confirmed that I had Inflammatory Arthritis, I could hardly walk. I was sent to

a Rhuematologist who did extensive blood tests (about 15 in all) and X-rays of

hands and feet, he couldn't find what was causing the Inflammatory Arthritis, so

discharged me back to the G.P. After this I changed my from synthetic thyroxine

to Natural Dessicated Thyroxine called Erfa. I would like to say importantly

that at the time of having the blood tests that indicated I had Inflammatory

Arthritis some months ago I also had a blood test at the same time for T3 which

indicated that my T3 levels were 'Normal' I have the results at home and it is

absolutely 'Normal' so this obviously indicates that the synthetic thyroxine

that I was taking was converting T4 into T3 (my T4 was also Normal at this

time), so if the T4 was Normal and the T3 was Normal then I can only assume that

the synthetic thyroxine that I was taking which was prescribed by the G.P. was

giving me a severe allergic reaction and causing excruciating joint pain and

inflammation. Since changing to Natural Dessicated Thyroid Erfa the pains have

gradually gone over the last few months and now I can honestly say that I am

100% o.k.with no more pains at all. So please can you answer me and let me know

if what I presume is correct and that I was allergic to synthetic thyroxine?

Thanks. Ann
