After a nuclear emergency, or when a nuclear crisis is imminent, it is common to hear of potassium iodide stockpiling. While it may be prudent to have potassium iodide on hand for such instances, wise use of the medication is essential to avoid dangerous interactions, overdose and even death as a result of ingestion.
Identification
Synonyms for potassium iodide are KI, potide, hydriocic acid and iodic acid. The potassium salt version of iodide, potassium iodide, is white in color, odorless and crystalline in nature. A naturally occurring oral medication, potassium iodide comes in syrup, uncoated and coated tablet form. The coated tablets are a delayed-release version of the drug. While potassium iodide is available by prescription through a physician, Mayo Clinic explains that over-the-counter varieties are also available.
Uses
Potassium iodide has several uses, most notably protection of the thyroid gland after exposure to nuclear radiation. A dose of potassium iodide may also follow the administration of radioactive iodine if you are receiving treatment for overactive thyroid. According to the Mayo Clinic, potassium iodide may also be part of a treatment regimen for patients undergoing thyroid surgery or patients who have an iodine deficiency. Some physicians prescribe potassium iodide to patients with skin fungal infections.
Possible Side Effects
Proper dosing by a physician is necessary when taking potassium iodide to avoid negative and sometimes serious side effects. The possibility of side effects increases if you have a thyroid disorder or allergy to shellfish. Stuart Heard, associate clinical professor of pharmacy at the University of California, San Francisco, explains that other serious side effects such as abnormal heartbeat, electrolyte imbalance, nausea, vomiting and bleeding may also occur after taking potassium iodide. Less serious side effects include tingling in the hands and feet, joint pain and a metallic taste in the mouth.
Consult Your Physician
Potassium iodide may react with other medications such as lithium and some diuretics and thyroid medications. These reactions can cause serious health risks that require immediate medical attention. If you take medication; have Addison's disease or heart, kidney or thyroid disease; are pregnant or considering becoming pregnant; or are nursing, it is imperative that you seek physician's approval prior to taking potassium iodine, according to the University of Arkansas for Medical Sciences.
