Buy Potassium Iodide

This fact sheet is about the NYS policy for people, especially those who live within ten miles of a nuclear power plant, who may be exposed to radiation from a nuclear plant emergency. In December 2001, the federal Food and Drug Administration (FDA) said if there was a radiation emergency, people should take a drug that would help protect them from thyroid cancer. This drug is called potassium iodide (KI). The New York State Health Department agrees. The questions and answers below will give you more information.

When you take potassium iodide, your thyroid gland absorbs it. If you get the right amount at the right time, it will saturate your thyroid gland. This can help block any inhaled or ingested radioactive iodine from being absorbed by your thyroid. This lowers your risk for radiation damage to that gland.

Potassium iodide is a salt, similar to table salt. Its chemical symbol is KI. It is routinely added to table salt to make it "iodized." Potassium iodide, if taken in time and at the appropriate dosage, blocks the thyroid gland's uptake of radioactive iodine and thus could reduce the risk of thyroid cancers and other diseases that might otherwise be caused by exposure to radioactive iodine that could be dispersed in a severe nuclear accident.

Potassium iodide is a special kind of protective measure in that it offers very specialized protection. Potassium iodide protects the thyroid gland against internal uptake of radioiodines that may be released in the unlikely event of a nuclear reactor accident.

When potassium iodide is ingested, it is taken up by the thyroid gland. In the proper dosage, and taken at the appropriate time, it will effectively saturate the thyroid gland in such a way that inhaled or ingested radioactive iodines will not be accumulated in the thyroid gland. The risk of thyroid effects is reduced. Such thyroid effects resulting from radioiodine uptakes due to inhalation or ingestion, or both, could result in acute, chronic, and delayed effects. Acute effects from high doses include thyroiditis, while chronic and delayed effects include hypothyroidism, thyroid nodules, and thyroid cancer.

The NRC did not require use of potassium iodide by the general public because the NRC believes that current emergency planning and protective measures--evacuation and sheltering--are adequate and protective of public health and safety. However, the NRC recognizes the supplemental value of potassium iodide and the prerogative of the States to decide the appropriateness of the use of potassium iodide by its citizens.

This rule applies to States and Tribal governments that have a nuclear power plant within their borders and populations within the 10-mile emergency planning zone and to local governments designated by States to request funding for potassium iodide.

A State considering the use of potassium iodide would at least review the regulation (66 FR 5427; January 19, 2001), the Federal Policy on the Use of Potassium Iodide, Food and Drug Administration (FDA) guidelines "Potassium Iodide as a Thyroid Blocking Agent in Radiation Emergencies," the FEMA guidelines, and the NRC disclaimer and would briefly deliberate the State's position on the use of potassium iodide by the general public in the unlikely event of a severe nuclear reactor accident.

In NRC's experience, States periodically review their emergency preparedness plans to ensure that the plans are up-to-date and account for the possibility of changed circumstances in any locality. NRC expects that States that routinely schedule periodic reviews of their emergency preparedness plans would consider use of potassium iodide during their first scheduled review. NRC expects that States that do not routinely conduct such reviews would consider the use of potassium iodide whenever they schedule periodic emergency preparedness exercises.

FDA is the Federal agency responsible for decisions about appropriate thresholds and dosages for use of potassium iodide. FDA published their final guidelines on the use of potassium iodide and included revised dosages and intervention levels: "Potassium Iodide as a Thyroid Blocking Agent in Radiation Emergencies." Additionally, FDA has published guidance on Home Preparation Procedure for Emergency Administration of Potassium Iodide Tablets to Infants and Small Children and also answered Frequently Asked Questions on Potassium Iodide (KI). To facilitate use of KI in emergency situations, on December 23, 2002, FDA published Guidance for Industry KI in Radiation Emergencies - Questions and Answers.

The population closest (within the 10 mile EPZ) to the nuclear power plant are at greatest risk of exposure to radiation and radioactive materials. The purpose of radiological emergency preparedness is to protect people from the effects of radiation exposure after an accident at a nuclear power plant. Evacuation is the most effective protective measure in the event of a radiological emergency because it protects the whole body (including the thyroid gland and other organs) from all radionuclides and all exposure pathways. However, in situations when evacuation is not feasible, in-place sheltering is substituted as an effective protective action. In addition, administering potassium iodide is a reasonable, prudent, and inexpensive supplement to both evacuation and sheltering. When the population is evacuated out of the area, and potentially contaminated foodstuffs are interdicted, the risk from further radioactive iodine exposure to the thyroid gland is essentially eliminated.

If terrorists attack either at a nuclear power plant or with a "dirty" bomb, radioactive iodine would have to be released in order for potassium iodide (KI) to be needed. Potassium iodide protects the thyroid gland only against the internal uptake of radioiodines.

For States interested in extending the shelf life of KI, the FDA has published guidance on shelf life extension for the tablet form of potassium iodide. Extending the shelf life of KI tablets is possible due to the inherent stability of the chemical form. However, the tablets must be stored under the conditions specified by the manufacturer to be considered for shelf life extension. In addition, this guidance only is intended for Federal agencies and State and local governments that maintain KI stockpiles under the conditions specified by the manufacturer.

Yes, potassium iodide tablets are inherently stable and do not lose their effectiveness over time. Manufacturers must label their products with a shelf-life to ensure that consumers purchase safe and useful products.

"On Jan. 2, I basically got in a month's supply of potassium iodide and I sold out in 48 hours," said Jones, 53, who is a top distributor of the drug in the United States. His Mooresville, N.C., company sells all three types of the over-the-counter product approved by the Food and Drug Administration. No prescription is required.

In that two-day period, Jones said, he shipped about 140,000 doses of potassium iodide, also known as KI, which blocks the thyroid from absorbing radioactive iodine and protects against the risk of cancer. Without the tweet, he typically would have sent out about 8,400 doses to private individuals, he said.

States with nuclear reactors and populations within a 10-mile radius of the reactors stockpile potassium iodide to distribute in case of an emergency, according to the Nuclear Regulatory Commission. An accident involving one of those reactors is far more likely than any nuclear threat from Kim Jong Un, Anbex's Morris said.

Stockpiling of potassium iodide (KI) is highly recommended by health officials worldwide to prevent thyroid cancer of those exposed to radioactive iodine. Radioactive iodine is the predominant radioisotope released from a nuclear reactor accident or detonation of a nuclear weapon (due to nuclear fission) and can travel thousands of miles downwind.

IOSAT Potassium Iodide is the only FDA Approved full strength tablet (130mg) available to the public. ThyroSafe Potassium Iodide is the only FDA Approved half-strength tablet (65mg) available to the public. Any non-FDA Approved brands of potassium iodide should be avoided.

"Emergency preparedness is a critical part of public health and having potassium iodide tablets for residents who live or work within 10 miles of an active nuclear facility is an essential preparation in the case of a radiological emergency," Acting Secretary of Health and Pennsylvania Physician General Dr. Denise Johnson said. "It's important to remember potassium iodide should only be taken when instructed to do so by state health officials or the governor, and it is not a replacement for evacuation in the case of a radiological emergency at one of Pennsylvania's four active nuclear facilities."

KI can add another layer of protection when instructed to be used. It helps protect the thyroid gland against harmful radioactive iodine and can be taken by anyone if they are not allergic to it. It is safe for pregnant women and those who are breastfeeding, people on thyroid medication, children and infants. Individuals who are unsure if they should take potassium iodide should ask a health care provider and only take if instructed to do so by state health officials or the governor.

Canadian Nuclear Safety Commission: Canadian Potassium iodide (KI) Pill Working Group- In 2019, the CNSC established a Potassium Iodide (KI) Pill Working Group and Advisory Committee to provide clarity on the existing plans and associated responsible authorities to distribute KI pills in the Ingestion Planning Zone (IPZ), in the event of an emergency at the Pickering Nuclear Generating Station. 041b061a72
