How many packs should I stockpile?

Storing at least one pack (14 tablets) PER person for each location frequented (home, 2nd home, relative’s home, childcare, office, etc.) is our recommendation. Iosat Potassium Iodide tablets should be immediately available in the event of a nuclear radiation emergency. To be most effective, the first dose should be taken no later than 2-3 hours prior to potential exposure to radioactive iodine (as directed by public health officials). Then, one dose every day (same time) until your family has evacuated to an uncontaminated area, and then stop taking the tablets (as directed by public health officials). Any remaining tablets will still be foil-sealed and available for a future need.
