On NDT and swinging between being under and over medicated?

[Guest guest]

Hi

I have been on Erfra since February this year and I have noticed some

improvement in my overall symptoms (was on thyroxine previously for 15yrs)My

problem sems to be around getting the dose of medication right for me. My Endo

commenced me on 120mgs Erfra initially but then when my blood tests were done 3

mths later the results were as follows

TSH - supressed

FT3 6.09 (3-5)

FT4 9.4 (7.5-21)

I was feeling slightly hyper, my Endo reduced my dose to 90mgs. But I have felt

worse on that dose and my blood results yesterday were

TSH - suppressed

FT3 3.4 (3-5)

FT4 6.6 (7.5 - 21)

Obviously everything is a bit too low.

The Endo has suggested I add in 25mcgs Thyroxine to see if things improve.

Anyone else have a similar problem on NDT?

Thanks for any help
