What is Potassium Iodide?
Potassium iodide is a chemical compound, medication, and dietary supplement. As a medication it is used to treat hyperthyroidism, in radiation emergencies, and to protect the thyroid gland when certain types of radiopharmaceuticals are used.
Potassium Iodide has been used since the 1820’s and is on the World Health Organization’s List of Essential Medicines, the most effective and safe medicines needed in a health system.
What Does this IOSAT Potassium Iodide Package Include?
Each standard package of IOSAT contains a strip of 14 tablets, with each tablet containing 130 mg of potassium iodide. The tablets are double scored to split easily and cleanly into 65 mg and 32.5 mg child doses. All IOSAT is fully U.S. Food and Drug Administration (FDA) approved for thyroid blocking in a radiation emergency.
Correct Dosage of Potassium Iodide
The FDA approved dosing of potassium iodide for this purpose with iobenguane, is as follows (per 24 hours): infants less than 1 month old, 16 mg; children 1 month to 3 years, 32 mg; children 3 years to 18 years, 65 mg; adults 130 mg. However, some sources recommend alternative dosing regimens. Way back in 1982, the FDA approved potassium iodide to protect thyroid glands from radioactive iodine involving accidents or fission emergencies. Since then, millions of people have used it to protect themselves in the event of radiation disaster.
Emergency 130 milligrams potassium iodide doses provide 100 mg iodide (the other 30 mg is the potassium in the compound), which is roughly 700 times larger than the normal daily nutritional need for an adult. The typical tablet actually weighs 160 mg. 130 mg of which is potassium iodide, and 30 mg being excipients, such as binding agents.
Side Effects of Potassium Iodide
As with any medication, use Potassium Iodide sparingly and only during emergency situations. Unnecessary use can cause conditions such as the Jod-Basedow phenomena, trigger and/or worsen hyperthyroidism and hypothyroidism, and can have adverse effects on the thyroid. It can also cause sialadenitis (an inflammation of the salivary gland), gastrointestinal disturbances, and rashes. Potassium iodide is also not recommended for people with dermatitis herpetiformis and hypocomplementemic vasculitis – conditions that are linked to a risk of iodine sensitivity. There have also been some reports of potassium iodide treatment causing swelling of the parotid gland (one of the three glands which secrete saliva), due to its stimulatory effects on saliva production. Other side effects include allergic reactions, headache, goitre, and depression. While use during pregnancy may be somewhat harmful the baby, its use is still recommended in radiation emergencies by the American Society of Health-System Pharmacists.
