iosat potassium iodide pills
FDA Approved 130mg and 65mg tablets for use by adults and children in a radiation emergency
Potassium iodide (KI) is a salt that can help protect your thyroid from absorbing radioactive iodine if you ever find yourself exposed to it. It works by blocking the absorption of radioactive iodine, shielding your thyroid from harmful effects.
However, it does not protect other parts of your body from radiation or reverse any damage already done to the thyroid. The FDA released guidance in December 2001 on how to safely use potassium iodide in pill or liquid form as a preventive measure during nuclear radiation emergencies.
How Does Potassium Iodide(KI) Work?
Evacuation is the most effective way to stay safe in case of a radiation emergency. However, taking potassium iodide can offer an additional layer of protection. This compound binds with the thyroid gland and prevents it from absorbing any radioactive iodine that may have been inhaled or consumed. The correct dosage administered at the right time will ensure maximum effectiveness in protecting your thyroid from radiation damage.
When is the best time to take potassium iodide Pills?
If you're advised to take potassium iodide tablets during an emergency, you should follow the instructions from your local health department. Ideally, take the medication before or right after being exposed to radioactive iodine. If it's not possible, it can be taken up to 3-4 hours after exposure, but it won't be as effective. Take the medication once a day until the risk of radiation exposure is gone and don't increase doses unless told to by experts - larger amounts won’t provide more protection but could cause side effects.
To ensure the longest shelf life of your potassium iodide, store it in a dark, dry and cool environment. With this type of storage, the chemical can last up to 5 to 7 years.
