These compounds contain iodine, but not in the iodide form. Thyroid iodine uptake blockade with potassium iodide is used in nuclear medicine scintigraphy and therapy with some radioiodinated compounds that are not targeted to the thyroid, such as iobenguane ( MIBG), which is used to image or treat neural tissue tumors, or iodinated fibrinogen, which is used in fibrinogen scans to investigate clotting. Radioactivity is also seen in the bladder. However, note unwanted uptake of radioiodine from the pharmaceutical by the thyroid gland in the neck, in both images (front and back) of the same patient. Image is by MIBG scintigraphy with radiation from radioiodine in the MIBG. Pheochromocytoma seen like a dark sphere in center of the body. Dextrose or sodium thiosulfate are often added to iodized table salt to stabilize potassium iodide thus reducing loss of the volatile chemical. Potassium iod ate ( K I O 3) is used to iodize some salts so that the iodine is not lost by oxidation. ![]() The alkali metal iodide salt, over time and exposure to excess oxygen and carbon dioxide, slowly oxidizes to metal carbonate and elemental iodine, which then evaporates. The oxidation of iodide causes slow loss of iodine content from iodised salts that are exposed to excess air. In humans it is the most common additive used for "iodizing" table salt (a public health measure to prevent iodine deficiency in populations that get little seafood). Potassium-iodide is a nutritional-supplement in animal feeds and also in the human diet. Potassium iodide is also used for the iodization of salt. ![]() Potassium iodide is available as a generic medication and over the counter. It is on the World Health Organization's List of Essential Medicines. Potassium iodide has been used medically since at least 1820. Commercially it is made by mixing potassium hydroxide with iodine. Potassium iodide has the chemical formula K I. While use during pregnancy may harm the baby, its use is still recommended in radiation emergencies. Other side effects include allergic reactions, headache, goitre, and depression. Ĭommon side effects include vomiting, diarrhea, abdominal pain, rash, and swelling of the salivary glands. It is a supplement used by people with low dietary intake of iodine. In the third world it is also used for treating skin sporotrichosis and phycomycosis. It is a medication used for treating hyperthyroidism, in radiation emergencies, and for protecting the thyroid gland when certain types of radiopharmaceuticals are used. ![]() Potassium iodide is a chemical compound, medication, and dietary supplement.
