The body needs iodine for normal growth and health. For patients who are unable to get enough iodine in their regular diet or who have a need for more iodine, sodium iodide may be necessary. Iodine is needed so that your thyroid gland can function properly. Iodine deficiency in the United States is rare because iodine is added to table salt. Most people get enough salt from the foods they eat, without adding salt to their meals.
Iodine deficiency is a problem in other areas of the world.
Lack of iodine may lead to thyroid problems, mental problems, hearing loss, and goiter. Injectable sodium iodide is administered only by or under the supervision of a health care professional. Follow carefully any diet program your health care professional may recommend. Iodine is found in various foods, including seafood, small amounts of iodized salt, and vegetables grown in iodine-rich soils. Iodine-containing mist from the ocean is another important source of iodine, since iodine is absorbed by the skin.
