Sodium iodide is used to prevent or treat iodine deficiency.
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. Some multivitamin/mineral preparations that contain sodium iodide are available without your health care professional's prescription.
Once a product has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although this use is not included in product labeling, injections of sodium iodide are used in certain patients with the following medical condition:
- Thyrotoxicosis crisis (severe overactive thyroid)
For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods. If you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement.
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. Iodized salt provides 76 micrograms (mcg) of iodine per gram of salt.
The daily amount of iodine needed is defined in several different ways.
- For U.S.—
- Recommended Dietary Allowances (RDAs) are the amount of vitamins and minerals needed to provide for adequate nutrition in most healthy persons. RDAs for a given nutrient may vary depending on a person's age, sex, and physical condition (e.g., pregnancy).
- Daily Values (DVs) are used on food and dietary supplement labels to indicate the percent of the recommended daily amount of each nutrient that a serving provides. DV replaces the previous designation of United States Recommended Daily Allowances (USRDAs).
- For Canada—
- Recommended Nutrient Intakes (RNIs) are used to determine the amounts of vitamins, minerals, and protein needed to provide adequate nutrition and lessen the risk of chronic disease.
