CYTOMEL® (liothyronine sodium) Indications and Usage


1.1 Hypothyroidism

CYTOMEL is indicated as a replacement therapy in primary (thyroidal), secondary (pituitary), and tertiary (hypothalamic) congenital or acquired hypothyroidism.

1.2 Pituitary Thyroid-Stimulating Hormone(TSH) Suppression

CYTOMEL is indicated as an adjunct to surgery and radioiodine therapy in the management of well-differentiated thyroid cancer.

1.3 Thyroid Suppression Test

CYTOMEL is indicated as a diagnostic agent in suppression tests to differentiate suspected mild hyperthyroidism or thyroid gland autonomy.

Limitations of Use

  • CYTOMEL is not indicated for suppression of benign thyroid nodules and nontoxic diffuse goiter in iodine-sufficient patients as there are no clinical benefits and overtreatment with CYTOMEL may induce hyperthyroidism [see Warnings and Precautions (5.4)].
  • CYTOMEL is not indicated for treatment of hypothyroidism during the recovery phase of subacute thyroiditis.
