Americans Race to Buy Potassium Iodide Pills

As the crisis at Japan's Fuksushima Daiichi Nuclear Power Plant continues, Americans are getting nervous about radiation poisoning. They are buying up potassium iodide pills in record amounts, with suppliers running out of stock.

Do You Need Potassium Iodide Pills?

If you live in the US (or anywhere in the Americas), you do not need potassium Iodide pills. The pills basically stock the thyroid with inert iodine, which prevents the uptake of radioactive iodine isotopes. However, there are no radioactive iodine isotopes reaching the Americas at this time.

No medical experts are currently suggesting that any Americans start taking potassium iodide.

Potassium Iodide tablets are not magic pills. If you were caught in a dangerously irradiated area (which, again, is not the case in the US), potassium iodide would only protect the thyroid, and no other parts of the body. One dose would be effective for up to 24 hours, provided that the patient leaves the irradiated area within that time.

We suggest reading Maggie Koerth-Baker's primer on Potassium Iodide, and why you shouldn't be stockpiling them if you live in the US.

Professor Gerry Thomas, chair in molecular pathology at Imperial College London, said the increase in sales was mostly due to irresponsible reporting. "If they [people in the US] are buying [potassium iodide] to protect themselves from radiation – what radiation?" she said. "This has been so massively overhyped by the media it's unbelievable."

Before you start swallowing any Poatasium Iodide Pill just note these side effects.

Usually side effects of potassium iodide happen when people take higher doses for a long time.  You should be careful not to take more than the recommended dose or take it for longer than you are told.  Side effects are unlikely because of the low dose and the short time you will be taking the drug.

Possible side effects include skin rashes, swelling of the salivary glands, and “iodism” (metallic taste, burning mouth and throat, sore teeth and gums, symptoms of a head cold, and sometimes stomach upset and diarrhea).

A few people have an allergic reaction with more serious symptoms.  These could be fever and joint pains, or swelling of parts of the face or body and at times severe shortness of breath requiring immediate medical attention.
