When you say a disaster on thyroxine, what exactly do you mean?

I have heard that there's no need to worry if your TSH goes right down when taking T3. That's all I can offer I'm afraid, I wouldn't call myself an expert yet! :) I'm glad you're feeling better.

Hi Superparrot thank you for your reply, Thyroxine did not suit me left me bedridden with severe flu like symptoms, irregular heart rate, & wildly fluctuating BP, so told to come off it, was very scary.

TSH is bound to be low or suppressed when taking any form of T3.

FT4 is irrelevant because you aren't taking any.

FT3 is still a bit low, plenty of room for an increase in dose. :)

Thank you greygoose, it is nice to be reassured, just looks alarming to see the T4 so low, although I know that is OK on T3 only, still nice to hear it from someone else.
