Iodide tablets

If a euthyroid goiter has not persisted for too long, increasing iodine supply (potassium iodide tablets) can also be effective in reversing overgrowth of the gland.

Potassium iodide is prepared in tablets, making it easier to store. Infants and children, though, cannot swallow tablets. When dissolved in water, the fluid is too salty to drink (Food and Drug Administration, 2002). To disguise the salty taste of the potassium iodide, the tablet can be crushed and mixed with raspberry syrup, low-fat chocolate milk, orange juice, or flat soda (cola) (Pelsor, Sadrieh, Machado, 2002). Nurses or parents can crush one 130-mg potassium iodide tablet into small pieces add 4 teaspoons of water to the crushed tablet to dissolve it then add 4 teaspoons of one of the aforementioned fluids to the mixture (U.S. Food and Drug Administration, 2002). Each teaspoon contains 16.25 mg of potassium iodide. This mixture will keep up to...

In humans, Murray and Pochin (1951) have confirmed that isotopic iodine from iodate is available to the thyroid when given per os, but the bioavailabifity was about 10% lower than that of iodide. Five milligrams of iodine weekly per os reduced goiter prevalence among iodine-deficient children equally well, whether given in the form of iodate or iodide tablets (Scrimshaw et al., 1953). However, this study does not prove exact bioequivalence of the two iodine compounds, since the iodine dose by far exceeded the physiological requirement, which might have obscured minor differences in bioequivalence. 

Although is a serious threat and has already caused much illness, it is also a threat that can be averted very simply. Some countries issue potassium iodide tablets (non-radioactive ) to their citizens. If these are taken in the wake of any news of a nuclear accident, then they would swamp the effect of any ingested radioactive iodide. Our thyroid gland cannot distinguish radioactive and non-radioactive iodide, and so, if, for the sake of argument the iodide tablet supplies a level of non-radioactive iodide a hundred times higher than the level of radioactive iodide taken in, this will decrease the effective risk by 99% by simple dilution. 

The source terms could also be used to demonstrate the effectiveness of sheltering, taking potassium iodide tablets, food bans and evacuation.

About one-half of the United States population take some type of vitamin and mineral supplement. Many of these include iodine, usually about 100-150 pg (10) in the form of iodide. Tablets containing from 100-500 pg of iodine are available in some countries with borderline iodine deficiency, such as Germany. 

Potassium Iodide tablets (10 mg) provided for mothers and small children in Canberra and the Australian Capital Territory. 

Potassium Iodide tablets given to all schoolchildren in Tasmania. 

In the districts receiving iodized salt, potassium iodide tablets are also givra, one per week to children and two per week to pr nant women. 

The Food and Drug Administration has recommended that potassium iodide tablets be administered for projected thyroid doses greater than 25 rem. Ingestion of potassium iodide (KI) tablets reduces the dose to the thyroid caused by the intake of radioiodine. It must be understood, however, that use of the thyroid-blocking agent potassium iodide (KI) is not an adequate substitute for prompt evacuation or sheltering by the general population near a...
