Labeled uses (from FDA prescribing information)
Strong Iodine Solution, containing 5 percent of iodine and 10 percent of potassium iodide, is employed in the prophylaxis of simple and colloid goiters and in the treatment of exophthalmic goiter. It can be used alone as a preoperative preparation but is now most commonly used concomitantly with propylthiouracil and other antithyroid drugs. When used with these drugs, Strong Iodine Solution produces involution of the hyperplastic gland thus making a less triable and vascular gland for thyroidectomy. In addition, it has an additive antithyroid action that helps make the patient enthyroid faster than if the antithyroid drugs were used alone.
