Summary
Potassium iodide (KI) is a type of iodine that is not radioactive and can be used to help block radioactive iodine (I-131) from being absorbed by the thyroid.
1
It is a medication used for treating hyperthyroidism, in radiation emergencies, and for protecting the thyroid gland when certain types of radiopharmaceuticals are used.
2
The Food and Drug Administration (FDA) recommends that KI should be taken for thyroid blocking radioactive exposure for individuals at risk for inhalation or ingestion of radioiodines.

KI products, such as iOSAT tablets, ThyroSafe tablets, and Potassium Iodide Oral Solution USP, are approved by the FDA and should be taken as a preventative before radiation exposure.

Summary
The Food and Drug Administration (FDA) issued a final Guidance on Potassium Iodide as a Thyroid Blocking Agent in Radiation Emergencies in December 2001. The FDA recommends that KI should be taken for thyroid blocking radioactive exposure for individuals at risk for inhalation or ingestion of radioiodines, and that it should not be taken as a preventative before radiation exposure. The FDA has approved several KI products, including iOSAT tablets, ThyroSafe tablets, and Potassium Iodide Oral Solution USP, and recommends that those at high risk should receive the full adult dose (130 mg) and those over 40 should only take KI if the predicted exposure is high enough to destroy the thyroid and induce lifelong hypothyroidism.
