From my endocrinologist (May, 2018), “For people with a history of thyroid cancer, keep the TSH level in a range of 0.1 to 0.5.”
My previous dose was too high, and my TSH level was basically 0.0 (which I could tell because my heart was racing), but by reducing the synthroid/levothyroxine dosage, it’s now in that range once again.
