Potassium Iodide, KI oral solution or syrup

What is potassium iodide oral solution or syrup?

POTASSIUM IODIDE, KI (Pima®, SSKI®) is a medicine that provides iodine. Iodine helps to treat many different conditions, especially conditions of the thyroid gland. Potassium iodide is commonly given to treat hyperthyroidism or to help prepare the thyroid gland for thyroid surgery. Potassium iodide has also been used to treat certain skin conditions. While this drug was once used to help coughs and clear mucus from the chest, it is now thought to be ineffective. Potassium Iodide should generally only be used under the prescription or advice of a health care professional with prescriptive authority.

Some Potassium Iodide products are intended to be used to protect the thyroid gland against radiation injury (example: ThyroShield® non-prescription oral solution). and are used only to protect the thyroid gland from exposure to radioactive iodine, which may occur in the event of a nuclear plant accident or an attack with nuclear weapons. To be effective, the oral solution needs to be taken as soon as possible in the event of a radioactive incident, preferably within a few hours. Potassium iodide cannot protect against all types of radiation exposure or injury. At this time, only certain products are FDA-approved for this purpose. Also, solutions intended for use only in radiation emergencies should not be used for other medical purposes. Use for radiation protection should be under the guidance of a prescriber or public health authority.
