(also called K1) is a salt of stable (not radioactive) iodine. Stable iodine is an important chemical needed by the body to make thyroid hormones. K1 is stable iodine in a medicine form. What can Potassium Iodide do?
Following a radiological or nuclear event, radioactive iodine may be released into the air or absorbed by contaminated food or water. When absorbed by the thyroid gland, this radioactive material can injure the gland and cause serious problems. To combat this issue, you can take Potassium Iodide so your body absorbs stable iodine instead of radioactive. When should I take Potassium Iodide?
Local public health or emergency management officials will tell the public if Potassium Iodide or other protective actions are needed. When advised, adults should take one 130 milligrams tablet. Children between 3 and 18 years of age should take 65 milligrams - tablets are scored in half for this purpose. A smaller amount is recommended for children under 3 years of age.
