Suppressed TSH isn't a problem as long as FT3 is in range. Have you seen Dr Toft's article in Pulse magazine - from thyroiduk.org.uk/tuk/about_... > Treatment Options
" Dr Toft states in Pulse Magazine, "The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l.
In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l. Most patients will feel well in that circumstance.
But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l.
This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l)."
Dr Toft is past president of the British Thyroid Association and leading endocrinologist.
But at the end of the day it's about you feeling optimally medicated and well and the dose and test results that achieve that.
I can't comment on the acne being a sign of overmedication, it's not something I have experience of.
