Oral administration of Lugol's iodine solution minimizes thyroid vascularity and provides short-term prevention of thyroid hormone production. The use of this drug also inhibits absorption of radioactive substances, which leads to a reduced risk for thyroid cancer, notes the Institute for Safe Medication Processes.
Lugol's iodine solution may prove beneficial for patients undergoing thyroid surgery since this medication is purported to lessen the amount of blood loss during this procedure. It also treats overactive thyroid conditions such as hyperthyroidism and thyroid storm following an operation.
Due to its antiseptic properties, Lugol's iodine solution is also used as a topical disinfectant, germicide and fungicide, states Drugs.com. However, as of 2015, the United States Food and Drug Administration does not consider this drug to be particularly safe and effective. Iodine poisoning may also result from the use of Lugol's iodine solution, cautions MedlinePlus.
