These dosages list mass of potassium iodide rather than elemental iodine. [17] [16] Potassium iodide can be administered as tablets or as Lugol's iodine solution. [16] The same dosage is recommended by the US Food and Drug Administration. [18] A single daily dose is typically sufficient for 24-hour protection. [16]

It can also be prepared by adding iodine to a hot, concentrated solution of potassium hydroxide: [1] 3 I 2 + 6 KOH → KIO 3 + 5 KI + 3 H 2 O. Or by fusing potassium iodide with potassium chlorate, bromate or perchlorate, the melt is extracted with water and potassium iodate is isolated from the solution by crystallization: [2] KI + KClO 3 → ...
Potassium iodate, KIO 3, like potassium iodide, has been issued as a prophylaxis against radioiodine absorption in some countries. [4] [5] It is also one of the iodine compounds used to make iodized salt. [6] Potassium hydrogen iodate (or potassium biiodate), KH(IO 3) 2, is a double salt of potassium iodate and iodic acid, as well as an acid ...

The "2% free iodine" description is based on the quantity of elemental iodine, not sodium/potassium iodide. [citation needed] USP Strong Iodine Tincture is defined in the NF as containing in each 100 mL, 6.8 to 7.5 gram of iodine, and 4.7 to 5.5 gram of potassium iodide. Purified water is 50 mL and the balance is alcohol.
