Eight euthyroid subjects were administered 500μg of thyrotropin-releasing hormone intravenously before and after the administration of 10mg potassium iodide daily for 7 days.

It is suggested that the administration of 10mg/day of potassium iodide can produce similar changes in serum TSH to those in previous reports using large doses of iodide
