Indications & Clinical Uses

Cytomel 5 mcg is a thyroid hormone medication used to treat conditions related to thyroid dysfunction. It is primarily indicated for the following:

  • Hypothyroidism: Replaces or supplements natural thyroid hormones in individuals with underactive thyroid glands.
  • Thyroid Cancer: Used as an adjunct to surgery and radioiodine therapy to suppress thyroid-stimulating hormone (TSH) in the management of well-differentiated thyroid cancer.
  • Thyroid Suppression Test: Helps differentiate suspected mild hyperthyroidism or thyroid gland autonomy.

How It Works

  • Liothyronine, the active ingredient in Cytomel 5 mcg, is a synthetic form of triiodothyronine (T3). It binds to nuclear thyroid hormone receptors, modulating gene transcription and increasing the basal metabolic rate. This action helps regulate metabolic processes, including growth and development, as well as the functioning of the heart, brain, and other organs.
