1. WHAT IS THE THYROID GLAND?
A small gland located at the base of the throat, the thyroid contains the only cells in the human body capable of absorbing and storing iodine. When optimally functioning, it concentrates iodine from a person’s blood—obtained through food or iodized salt—and combines it with the amino acid, Tyrosine. This is then converted into the hormones that control a person’s metabolism and growth rate.
2. What is ThyroSafe?
Produced by Recipharm AB, Sweden, who which has more than 20 years experience in manufacturing Potassium Iodide tablets, ThyroSafe was developed to protect the thyroid against radioactive iodine released during a nuclear emergency. It is currently the only FDA approved 65 mg potassium iodide tablet on the market today in the United States. Each pill is also rigorously tested and formulated using only the purest methods available.
3. How Does Radiation Affect Human Health?
During a nuclear emergency, radioactive iodine is released into the air. Once swallowed or inhaled, it is then absorbed into the thyroid gland. Even the smallest amount of radioactive iodine can result in abnormalities later in life, including but not limited to: loss of thyroid functions, nodules in the thyroid, or thyroid cancer. It is important to note that children are extremely susceptible to these conditions due to their especially active thyroids.
4. Why Use ThyroSafe?
Potassium iodide (KI) has a well-researched effectiveness in blocking blocking the ill effects of radioactive iodine found in fallout from a nuclear explosion of any kind. When taken in the recommended dose, ThyroSafe will effectively saturate the thyroid gland in such a way as to prevent the accumulation of inhaled or ingested radioactive iodines. Therefore, the overall risk of thyroid cancer is significantly reduced.
5. How Safe is ThyroSafe?
As reported in the American Journal of Medicine (Volume 94, P.524-532, May, 1993), side effects among the roughly 18 million individuals who took Potassium Iodide (KI) after the Chernobyl accident were minimal. Approximately 3% suffered some form of upset stomach (due, in part, to a liquid KI being used instead of a tablet); 1% developed a mild skin rash; and 1% suffered other mild symptoms. Only 2 cases of more serious side effects were ever noted, and both occurred among people with known allergies to iodide.
6. What is the Shelf Life of ThyroSafe?
Shelf life is an arbitrary time period that the FDA says is the usable life of the product. All batches of ThyroSafe should have greater than 7 years of shelf life when ordered from the manufacturer.
7. Is ThyroSafe Safe for Expecting Mothers?
According to the FDA, pregnant women should be given potassium iodide (KI) for their own protection and for that of the fetus as iodine (whether stable or radioactive) can readily cross the placenta. However, because of the risk of blocking fetal thyroid function with excess stable iodine, repeat dosing of KI should be avoided.
8. Who should not take ThyroSafe or have restricted use?
According to the FDA, individuals with known iodine sensitivity should avoid ThyroSafe, as should those with dermatitis herpetiformis and hypocomplementemic vasculitis; both extremely rare conditions associated with an increased risk of iodine hypersensitivity. Individuals with multi-nodular goiter, Graves’ disease, and autoimmune thyroiditis should utilize caution—especially if dosing extends into multiple days.
9. Why is ThyroSafe 65 mg?
ThyroSafe is the only FDA approved 65 mg potassium iodide (KI) tablet sold in the U.S. The FDA Guideline suggests, “For the sake of logistical simplicity in the dispensing and administration of KI to children, we recommend a 65 mg dose as standard for all school-age children, while allowing for the adult dose (130 mg, 2 x 65 mg.) in adolescents approaching adult size.”
10. When Should ThyroSafe Be Used?
ThyroSafe should be ingested as soon as possible, following an alert from public health officials. If health officials instruct you to repeat the dose, you should take one tablet every 24 hours. Do not take any other potassium iodide (KI) products unless instructed to do so by authorities.
11. How is ThyroSafe Administered to Children?
One of the major advantages of ThyroSafe is our standard cross-score, which makes it easy to break into ½ or ¼ tablet to satisfy the graded dose requirement, as recommended by the FDA Guideline (see below).
Children ages 3 through 18 yrs
Children over 1 month through 3 yrs
For small children who cannot swallow the tablet with water, the required fraction of tablet should be ground into a powder and then dissolved in water or other preferable drink. If you have difficulty breaking ThyroSafe into ¼ tablet, take ½ tablet and follow the above procedure. For more information on treating infants, visit the U.S. FDA’s discussion of the topic at:
