Lugols solution

This medication contains iodine and potassium iodide. It is used along with antithyroid medicines to prepare the thyroid gland for surgical removal and to treat certain overactive thyroid conditions (hyperthyroidism, thyroid storm). It works by shrinking the size of the thyroid gland and by decreasing the amount of thyroid hormones the body makes.This medication may also be used to protect the thyroid gland after radioactive iodine treatment or in a radiation exposure emergency. In such cases, this product blocks the thyroid gland from absorbing radioactive iodine, protecting it from damage and reducing the risk of thyroid cancer. In a radiation exposure emergency, use this medication along with other emergency measures that will be recommended to you by public health and safety officials (such as finding safe shelter, evacuation, controlling food supply).This medication may also be used for other conditions as determined by your doctor (such as treatment of iodine deficiency).
