Levothyroxine is taken on an empty stomach about half an hour to an hour before meals. [21] As such, thyroid replacement therapy is usually taken 30 minutes prior to eating in the morning. [14] For patients with trouble taking levothyroxine in the morning, bedtime dosing is effective, as well. [14]
A radioactive iodine uptake test and thyroid scan together characterizes or enables radiologists and doctors to determine the cause of hyperthyroidism. The uptake test uses radioactive iodine injected or taken orally on an empty stomach to measure the amount of iodine absorbed by the thyroid gland.
The onset of anti-thyroid effect is rapid but the onset of clinical effects on thyroid hormone levels in the blood is much slower. This is because the large store of pre-formed T 3 and T 4 in the thyroid gland and bound to thyroid binding globulin (99% bound) has to be depleted before any beneficial clinical effect occurs.

The Wolff–Chaikoff effect is known as an autoregulatory phenomenon that inhibits organification in the thyroid gland, the formation of thyroid hormones inside the thyroid follicle, and the release of thyroid hormones into the bloodstream. [6] This becomes evident secondary to elevated levels of circulating iodide.
The syndrome can present with variable symptoms, even between members of the same family harboring the same mutation. [1] Typically most or all tissues are resistant to thyroid hormone, so despite raised measures of serum thyroid hormone the individual may appear euthyroid (have no symptoms of over- or underactivity of the thyroid gland).
