Tiratricol is not approved for sale in Canada or the United States. It was once an approved medication in Brazil, but its marketing authorization was suspended in 2003, effectively prohibiting its sale. [3] Tiratricol is available in France for therapy of thyroid hormone resistance and adjuvant therapy of thyroid cancer. [4]
In Graves' disease, treatment with antithyroid medications must be given for six months to two years, in order to be effective. Even then, upon cessation of the drugs, the hyperthyroid state may recur. Side effects of the antithyroid medications include a potentially fatal reduction in the level of white blood cells.
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.
Wilson's (temperature) syndrome, also called Wilson's thyroid syndrome or WTS, is a term used in alternative medicine to improperly attribute various common and non-specific symptoms to abnormally low body temperature and impaired conversion of thyroxine (T4) to triiodothyronine (T3), despite normal thyroid function tests.

Researchers from Johns Hopkins University School of Medicine in Baltimore, MD, showed that total body bone mass and density both decreased in adults over the age of 65 who received levothyroxine ...
Certain medications can have the unintended side effect of affecting thyroid function. While some medications can lead to significant hypothyroidism or hyperthyroidism and those at risk will need to be carefully monitored, some medications may affect thyroid hormone lab tests without causing any symptoms or clinical changes, and may not require treatment.
Thiamazole is a cyclic thiourea derivative that works by decreasing the production of thyroid hormones. [2] Thiamazole was approved for medical use in the United States in 1950. [2] It is on the World Health Organization's List of Essential Medicines. [5] [6] It is available as a generic medication. [2] It is also available in Europe and Asia. [7]
Repeat thyroid function tests should be done five weeks after the dosage is increased. [14] While a minimal amount of thyroid hormones is found in breast milk, the amount does not influence infant plasma thyroid levels. [18] Furthermore, levothyroxine was not found to cause any adverse events to the infant or mother during breastfeeding. [18]
