The Federal Drug Administration (FDA) provides the names, websites and phone numbers of three companies that offer tablets and information on potassium iodide, which are Anbex, Inc., Recip, and Fleming & Company Pharmaceuticals. The names of the specific potassium iodide tablet offered by these companies are Iosat tablets, ThyroSafe and ThyroShield Solution, respectively. Potassium iodide is a chemical salt compound that has the chemical formula KI.
Potassium iodide is available without a prescription to the general public and may be bought online. Iosat tablets are available in 130 milligrams while ThyroSafe comes in 65 milligrams.
Potassium iodide is important in blocking the absorption of radioactive iodine by the thyroid gland that can occur if a person is exposed to nuclear radiation, explains the United States Centers for Disease Control and Prevention (CDC). Exposure to radioactive iodine can lead to thyroid cancer, and individuals who are at the highest risk for this are infants, children and pregnant women. However, anyone older than age 40 should not take potassium iodide unless there is a chance that contamination may come from a large dose of radioactive iodine, specifies the CDC.
The FDA has a chart detailing the correct dosage of potassium iodide for different groups of people and exposure levels. It is important to take the correct or recommended dose of this substance because higher doses can cause health problems or even death, states the CDC.
