This guidance provides answers to questions that FDA has received as state and local governments develop emergency response plans involving the use of potassium iodide (KI) to protect against the effects of radioactive iodine accidentally or intentionally released into the atmosphere. KI is recommended for use as an adjunct to other emergency measures, such as evacuation and control of the food supply to avoid ingestion of contaminated foodstuffs. When used correctly, KI can prevent or reduce the uptake of radioiodine by the thyroid gland. KI provides optimal protection when administered immediately prior to or in conjunction with passage of a radioactive cloud. The incorporation of KI into radiation emergency response plans is at the discretion of state and local governments.
