Y1 - 2019 N1 - T2 - Goldfrank's Toxicologic Emergencies, 11e AB - Potassium iodide (KI) is the antidote to radioactive iodine that is released into the atmosphere after a nuclear incident. It is approved as a specific competitive inhibitor of thyroid uptake of radioiodine to reduce the risk of thyroid cancer in susceptible populations. The indications for its use are complex, and initiation and maintenance of therapy require great attention to the details of the circumstances of the exposure to limit harm that would result from either under treatment or overtreatment.
