ThyroSafe is the only FDA approved Potassium Iodide (KI) tablet with 65 mg. strength.

ThyroSafe™ is an over the counter pharmaceutical product produced by Recipharm AB, a Swedish company and sold by its U.S subsidiary, Recipharm Inc. Brought to the United States after the September 11th attacks, ThyroSafe™ is the only FDA approved 65 milligram potassium iodide product sold in the U.S. The function of ThyroSafe™ is to provide protection against the effects of radioactive iodine, the major component of a nuclear accident or nuclear terror attack. In such an emergency, radioactive iodine is released into the air in what is known as “fall-out” which may be inhaled or swallowed. The thyroid gland needs iodine to make hormones that control metabolism and regulate growth. When fall-out occurs, the thyroid gland cannot distinguish between regular iodine and radioactive iodine and if radioactive iodine has been released into the atmosphere by a nuclear emergency, it can be absorbed by the thyroid gland.

If harmless potassium iodide, like ThyroSafe™, fills the thyroid gland there is no room for radioactive iodine to affect the gland and its function. That is how ThyroSafe™ protects you and your children from the possibility of developing thyroid abnormality, or even cancer years after a nuclear emergency.

ThyroSafe™ tablets are the only FDA approved potassium iodide tablet that comes in the child appropriate 65 milligram dosage sold in the U.S. In case of a radiation emergency, and upon notification by local health authorities, children aged three (3) to eighteen (18) take one tablet daily. Children one month to three year of age take one-half tablet. Neonates under one month should take one-quarter tablet. Adults over eighteen years of age take two tablets daily. Local health authorities will inform you how long to continue taking ThyroSafe™. FDA & NRC also favors that child dosing formulation for civilian populations over solely dispensing adult doses needing to then be split and quartered and 8thed for children.

    Radioactive Iodine (Radioiodine) is a major radioisotope constituent of both nuclear power plant accidents and nuclear bomb explosions and can travel hundreds of miles on the winds. Thyroid cancer attributable to Chernobyl "...has been documented up to 500 km from the accident site." The maximum measured radioactive contamination of milk in the United States by radioiodine from the Chernobyl disaster was in milk produced by cows grazing on pasture in Washington: 560 picocuries per liter. Customary levels are normally 2-3 picocuries per liter.

    Even very small amounts of inhaled or ingested radioiodine can do grave damage as it will always concentrate, and be retained, in the small space of the thyroid gland. Eventually giving such a large radiation dose to thyroid cells there that abnormalities are likely to result, such as loss of thyroid function, nodules in the thyroid, or thyroid cancer. (Each year 12,000 Americans discover they have thyroid cancer, though from various assorted causes, and about 1000 die from it.)

    Chernobyl has shown, and continues to reveal, that the greatest danger from radioiodine is to the tiny thyroid glands of children. Researchers have found that in certain parts of Belarus, for example, 36.4 per cent of children, who were under the age of four at the time of the accident, can expect to develop thyroid cancer.

    Health experts now estimate that the greatest health concerns affecting the largest number of people from a nuclear accident, or nuclear bomb explosion(s) anywhere in the world, will likely be from the release of radioiodine that is then carried downwind for hundreds of miles. While there will also be many other dangerous radioisotopes released along with radioiodine, if they are inhaled or ingested they are normally dispersed throughout a body and pose less of a risk than if they were to be concentrated into one small specific area of the body, like radioiodine is in the thyroid gland. So, as a plume or cloud of radioactive isotopes disperses with the wind its danger also diminshes, but much less quickly so for radioiodine because whatever little there is left, that's inhaled or ingested, will always then be concentrated into that small space of the thyroid gland.

    The good news is that taking either Potassium Iodide (KI) or Potassium Iodate (KIO3) before exposure will saturate (fill up) a persons thyroid gland with safe stable iodine to where there is no room for later uptake of radioactive iodine. Once the thyroid is saturated, then any additional iodine (radioactive or stable) that is later inhaled or ingested is quickly eliminated via the kidneys.

    Potassium Iodide (KI) and/or Potassium Iodate (KIO3) has already been stockpiled by most developed countries for future nuclear emergencies, they figured it out after Chernobyl, but here in the USA they've only just begun. (We sold 300,000 doses to HHS Office of Emergency Prepardness after 9/11, which represented half of our nations stockpile then.) However, very limited quantities will be available for individual purchase in the USA by the public after an 'event'. (Potassium Iodide (KI) has long been recognized and approved by the FDA for sale for this purpose without a prescription. Unfortunately, it is an over-the-counter (OTC) drug that's to be found on too few counters here in the USA!)

    P.S.- KI or KIO3 would likely not be needed for the so-called 'Dirty Bomb' or RDD (Radiological Dispersal Device). Radioactive Iodine is only produced in quantity by a fission or fusion weapon detonation or in a Nuclear Power Plant as a byproduct of that process. There is some small medical radioactive iodine, but it's impractical as a bomb component with its short half-life. An RDD simply spreads around existing radioactive material and it's not very likely to have been composed of the relatively short half-life radioactive iodine. We'd more likely see used in an RDD a commercially abundant, and more easily obtained, isotope like Cobalt-60, Cesium-137 or uranium fuel rods, etc.
