Patient Education

Potassium Iodide


Potassium iodide is used to protect the thyroid gland from taking in radioactive iodine that may be released during a nuclear radiation emergency. Radioactive iodine can damage the thyroid gland. You should only take potassium iodide if there is a nuclear radiation emergency and public officials tell you that you should take it. Potassium iodide is in a class of medications called anti-thyroid medications. It works by blocking radioactive iodine from entering the thyroid gland. Potassium iodide can protect you from the effects of radioactive iodine that may be released during a nuclear radiation emergency, but will not protect you from other dangerous substances that may be released during the emergency. Public officials may tell you to do other things to protect yourself during the emergency. Follow all of these directions carefully.
