iOSAT™ Potassium Iodide (KI) Tablets, USP, 130 mg are fully FDA approved for thyroid blocking in a radiation emergency.  IOSAT is the only full-strength potassium iodide tablet approved by the FDA that can be sold in the US, and which is approved for government purchasing.


Also, be aware that IOSAT contains potassium iodide, not iodate, which is not FDA approved and is not legal to sell in the US. Statements by other companies that they are FDA approved or that iodide and iodate are equivalent are either untrue or misleading.


Each standard package of IOSAT contains a strip of 14 tablets, with each tablet containing 130 mg of potassium iodide.  The tablets are double scored to split easily and cleanly into 65 mg and 32.5 mg child doses.


Each IOSAT tablet is individually wrapped in a foil blister packet.

*Many products will require the use of a direct shipping quote from one of our CSR agents due to new DIM weights and measure changes as of Jan 10th, 2018 from major carriers.

Packages greater than a square cubic foot are now required to use a “volumetric weight” based upon length, width, height of a package from most carriers which alters actual weights. Oversized / Unique shaped packages are most affected and may not apply to your specific purchase(s). However, IN ORDER to save you, the customer, shipping costs, associated fees, and to keep product costs down, we are taking action to give direct shipping quotes based upon delivery methods available. Your full name and email address, required in the checkout, is so we can offer you a shipping quote. Your item(s) will NOT ship without communication from our CSR agents. We apologize for any inconveniences.*
