Can a person allergic to iodine still take potassium iodide?

Yes.: This involves one of the most popular medical myths. If you are allergic to seafood, you are not allergic to iodine, contrary to very popular belief. (some doctors even have this misconception.) theoretically it is not possible to be allergic to elemental iodine or simple iodide salts (such as potassium iodide) at all. Iodine can cause a non-allergic reaction called iododerma, however.
