Levothyroxine and Potassium Iodide Are Both Effective in Treating Benign Solitary Solid Cold Nodules of the Thyroid

Abstract

Levothyroxine and, to a lesser extent, potassium iodide are effective in arresting the growth or in reducing the volume of benign solitary solid cold thyroid nodules, especially small ones; discontinuation of therapy may result in resumed nodule growth.
