Which brands are FDA approved? 

Search the FDA Orange Book Database. There are only TWO brands of potassium iodide that can legally sold in the U.S. to prevent thyroid cancer from radiation exposure. EVERY Iosat™ batch is analyzed by the FDA for safety, quality, efficacy and 10-year shelf life sustainability.

How many should I stockpile?

Storing at least one pack (20 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.

Can adults take the 65mg tablet? Does it protect adults just the same as the 130mg tablet?

Absolutely. The only medicinal difference is the milligram (mg) strength of the tablet. The 65mg tablet contains exactly half of the active ingredient, iodine, as the 130mg tablet. So, an adult would take two 65mg tablets each day (130mg/day) – much like taking two ibuprofen or two aspirin. And children would take just a maximum of one 65mg tablet a day.

Why did Anbex introduce 65mg iOSAT™ Potassium Iodide (KI)?

LOWEST EFFECTIVE DOSING
The FDA recognized that an age/weight-appropriate, lower-dose iOSAT™ 65mg tablet would safely and effectively saturate a child’s thyroid gland with stable iodine – (without the need of splitting a 130mg tablet). Thus, preventing their thyroid from absorbing thyroid cancer-causing radioactive iodine from a nuclear source – the same as the iOSAT™ 130mg adult-strength tablet has done since its FDA approval in 1982.

HALF THE SIZE
The 65mg tablet for children is exactly half the weight AND half the thickness of the 130mg adult-strength tablet, making it easier for children to quickly swallow in a nuclear radiation emergency. It’s half-size also quickens the needed crushing/dissolving into food or drink so as to administer to a child who can’t swallow a pill.

AND SCORED
The 65mg tablet is scored – allowing quick and accurate splitting for even lower doses to children under 3 (see Consumer Package Insert images below).
