The goal may change to a level within the normal range, rather than below it, as time goes on. In people who are medium or high risk, the dose will be high enough to suppress the thyroid stimulating hormone (TSH) below the range that is normal for someone not diagnosed with thyroid cancer.Do this for all of your prescriptions, not just levothyroxine.

There are three main blood tests: Thyroid Stimulating Hormone (TSH).After dose adjustments, the mean therapeutic levothyroxine doses after total thyroidectomy and lobectomy were 1.5 and 1.3 g/kg, respectively. A regression model incorporating other patient factors did not produce a more reliable dosing regimen.
Results Four hundred four patients were included; 85 were women. The mean initial levothyroxine dosage was 1.4 g/kg, which resulted in thyroid-stimulating hormone normalization in 59, suppression in 23, and elevation in 18 of patients.This is because the blood levels of the hormone are more predictable with the synthetic forms than the animal source pills.
