These preparations can both aggravate thyroid disorders and alter thyroid function test results. Consequently, problems arise when physicians prescribe levothyroxine based on misleading test results caused by over-the-counter products. Unfortunately, over-the-counter iodine and thyroid supplements are readily available on the Internet, in health food stores, and in some grocery and drug stores.
Very few sites list the ingredients or the amounts of the ingredients in these products. Therefore, patients cannot possibly know what they are taking and neither can the physicians writing levothyroxine prescriptions.
