Interactions with Drugs

Amiodarone (Cordarone®) contains significant amounts of iodine. Plasma iodine levels may be increased and additive with iodine supplements. Thyroid function should be monitored.

Concomitant use of angiotensin- converting enzyme inhibitors (ACE- I) or angiotensin receptor blockers (ARB) with potassium iodide increases the risk of hyperkalemia (high blood potassium levels). Examples of ACE inhibitors include benazepril (Lotensin®), captopril (Capoten®), enalapril (Vasotec®), fosinopril (Monopril®), lisinopril (Prinivil®, Zestril®), moexipril (Univasc®), perindopril (Aceon®), quinapril (Accupril®), ramipril (Altace®), and trandolapril (Mavik®). The ARBs include losartan (Cozaar®), valsartan (Diovan®), irbesartan (Avapro®), candesartan (Atacand®), telmisartan (Micardis®), and eprosartan (Teveten®).

Additive hypothyroid effects may occur with the use of iodine products in combination with antithyroid drugs (methimazole, propylthiouracil).

Additive hypothyroid effects may occur with the use of iodine products such as potassium iodide in combination with lithium salts. Lugol solution can increases lithium toxicity by inducing additive hypothyroid effects.

Concomitant use of potassium iodide with potassium- sparing diuretics may increase the risk of hyperkalemia (high blood potassium levels). Examples of potassium- sparing diuretics include spironolactone (Aldactone®), triamterene (Dyrenium®), and amiloride (Midamor®).

Interactions with Herbs and Dietary Supplements

Bugleweed (Lycopus virginicus/ Lycopus europaeus) may reduce iodine uptake.

High iodine content can be found in kelp/ seaweed/ bladderwrack and may add to the effects of iodine supplementation.

Ingestion of lithospermum may lower thyroid hormone blood levels and may interact with the effects of iodine on thyroid hormone levels.

Selenium deficiency may exacerbate the effects of iodine deficiency.

Iodine may interact with herbs and supplements with diuretic effects; use cautiously.
