A member asked:
Should methimazole be dosed on tsh or ft4, t4, t3, (liothyronine) ft3 levels?
A doctor has provided 1 answer
All of the above: Methimazole is a thionimide that inhibits the formation of thyroid hormone it is important to measure tsh, ft4 ; ft3 (liothyronine) levels to have a better idea of the physiology causing the hyperthyroidism, ie is it subclinical hyperthyroidism, t3 (liothyronine) preferential secretion, or severe thyrotoxicosis. The TSH can be very suppressed with only minimally elevated t4/t3 (liothyronine) which would not need as high a dose.
