Potassium iodide is a chemical compound, medication, and dietary supplement.[3][4] It is a medication used for treating hyperthyroidism, in radiation emergencies, and for protecting the thyroid gland when certain types of radiopharmaceuticals are used.[5] It is also used for treating skin sporotrichosis and phycomycosis.[5][6] It is a supplement used by people with low dietary intake of iodine.[4] It is administered orally.[5]

Common side effects include vomiting, diarrhea, abdominal pain, rash, and swelling of the salivary glands.[5] Other side effects include allergic reactions, headache, goitre, and depression.[6] While use during pregnancy may harm the baby, its use is still recommended in radiation emergencies.[5] Potassium iodide has the chemical formula KI.[7] Commercially it is made by mixing potassium hydroxide with iodine.[8][9]

Potassium iodide has been used medically since at least 1820.[10] It is on the World Health Organization's List of Essential Medicines.[11] Potassium iodide is available as a generic medication and over the counter.[12] Potassium iodide is also used for the iodization of salt.[4]
