TSH too low

[Lanvere]

Out of interest can your TSH get too low ... I've been really dizzy for 8 weeks doc says labrythitus but I just know it's not ... I take 100 micro grams thyroxine... last result was TSH 0.02 T4 15. Should I consider reducing dosage

Doubtful that would help. Your FT4 doesn't look high.

Once you are on thyroid hormone replacement, your TSH is irrelevant unless it goes high. It can go as low as it likes, because you don't need it anymore.

But, for the dizziness, you should perhaps get your nutrients tested. It could be low B12 or something. Always very difficult to find the reason for dizziness. I had it really bad at one time, and the doctor just gave me tablets that said the were for 'dizziness of unknown origine', and he refused to look for the origin! It's so much better now that my T3 and nutrients are optimised - more or less.
