Potassium Iodide

  $  $45.00 - 8 ounces

$  75.00  one pound bulk

In a radiation emergency, radioactive iodine may be released in the air by fallout or a nuclear plant explosion. Radioactive fallout has a half life of eight days and remains a threat for up to 80 days, for a total of @ 85 days. This material may be breathed or swallowed. It may enter the thyroid gland and damage it. The damage would probably not show itself for years. Children are extremely susceptible to thyroid cancer after exposure to radioactive contamination.

If you take potassium iodide, it will fill up your thyroid gland. This reduces the chance that harmful radioactive iodine will enter the thyroid gland.

Pregnant and nursing women and babies and children may also take potassium iodide.

Listen to news broadcast and take potassium iodide 3 - 12 hours before the fallout arrives.

Usual dosage is between 85mg and 130 mg.

Adults and children over 12 years of age:

Take: 2 capsules per day for 15 days (minimum) to 85 days

Children 3 years to 12 years:

Take: 1 capsule per day for 15 days (minimum) to 85 days

Babies 1 month to 3 years

Take: ½ capsule per day for 15 days (minimum) to 85 days

Newborns to 1 month:

Take: 1/4 capsule per day for 15 days (minimum) to 85 days

Pets: for 15 days (minimum) to 85 days

Large dog -- 1 - 2 capsules per day

Medium dog -- ½ to 1 capsule per day

Cats -- 1/4 to ½ capsule per day

Store at controlled temperature between 59 degrees to 86 degrees F. Keep bottle tightly closed and protect from light.

DO NOT SUBSTITUTE WITH iodine, iodine water purification tablets, tincture of iodine, or Povidone iodine solutions like betadine (These are poison taken internally).

DO NOT INDUCE VOMITING: Give milk, cornstarch or flour by mouth or just over a pint of water. Continue to give milk every 15 minutes.

Potassium iodide is an old drug used as an expectorant in the treatment of asthma, bronchitis and emphysema. It is used to treat coughs with phlegm, feeling of fullness in the chest or pressure in the face/sinuses. Potassium iodide helps loosen phlegm (mucus) and thin bronchial secretions to drain bronchial tubes and make coughs more productive. It increases secretions in the respiratory tract in approximately 30 minutes.

Potassium iodide also has anti-infective properties and is sometimes used to treat certain skin conditions caused by fungus, like toenail fungus.

Today it is mainly used to treat an overactive thyroid, and of course, to protect the thyroid gland from the effects of radiation from inhaled or swallowed radioactive iodine.


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 and body and a times severe shortness of breath requiring immediate medical attention.

Taking iodide may rarely cause over activity of the thyroid gland, underactivity of the thyroid gland, or enlargement of the thyroid gland (goiter)

If the side effects are severe or if you have an allergic reaction, stop taking potassium iodide. Then, if possible, call a doctor or public health authority for instructions.

About 1 person in 2 million people are allergic to potassium iodide. If a rash appears then you may be only mildly allergic. You must make the decision, which is worse--radiation or a rash!

Remember: children are extremely susceptible to radiation. They come first -- always!
