General description

Thyroxine (T4) is a tetraiodo derivative of the p-hydroxyphenyl ether of tyrosine, which functions as growth factors or cell growth inhibitors. T4 is used to treat hypothyroidism and thyroid carcinoma. It regulates energy metabolism.


L-Thyroxine has been used to investigate its role in colorectal cancer cell lines HCT 116 (APC wild type) and HT-29 (APC mutant). It has also been used to evaluate its effects on pro-inflammatory tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), angiogenic vascular endothelial growth factor (VEGF), leukocyte adhesion, intercellular adhesion molecule 1 (ICAM-1) and E-selectin in human umbilical vein endothelial cells (HUVECs).

L evothyroxine is used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. Having enough thyroid hormone is important for maintaining normal mental and physical activity. In children, having enough thyroid hormone is important for normal mental and physical development.This medication is also used to treat other types of thyroid disorders (such as thyroid cancer).This medication should not be used to treat infertility unless it is caused by low thyroid hormone levels.



Dosage & Route

Available forms : Tablets—25, 50, 75, 88, 100, 112, 125, 137, 150, 175, 200, 300 mcg; powder for injection—200, 500 mcg/vial

Dosages : 50–60 mcg equals approximately 60 mg (1 grain) desiccated thyroid.

  • Hypothyroidism: Initial dose, 50 mcg PO, with increasing increments of 25 mcg PO q 6–8 wk; maintenance of up to 200 mcg/day. IV or IM injection can be substituted for the oral dosage form when oral ingestion is not possible. Usual IV dose is 50% of oral dose. Start at < 25 mcg/day in patients with long-standing hypothyroidism or known cardiac disease. Usual replacement 1.7 mcg/kg/day.
  • Myxedema coma without severe heart disease: 200–500 mcg IV as initial dose, then 100 to 200 mcg IV daily; daily maintenance of 50 to 100 mcg once a euthyroid state is established. Switch to PO once patient is able. Full effect not seen for 24 hr; dose based on improvement.
  • TSH suppression in thyroid cancer, nodules, and euthyroid goiters: Larger amounts than used for normal suppression.
  • Thyroid suppression therapy: 2.6 mcg/kg/day PO for 7–10 days.
  • Older patients may require less than 1 mcg/kg/day. For most patients older than 50 yr or under age 50 with cardiac disease, an initial dose of 12.5 to 25 mcg/day with increases of 25 mcg/day q 4–6 wk.
