Iodine compounds:

  • Administer iodine compounds (Lugol iodine or potassium iodide) orally or via a nasogastric tube to block the release of THs (at least 1 h after starting antithyroid drug therapy). In adults, SSKI is a given at a dose of 5 drops every 6 hours, or Lugol's iodine at a dose of 10 drops every 8 hours. If available, intravenous radiocontrast dyes such as ipodate and iopanoate can be effective in this regard. These agents are particularly effective at preventing peripheral conversion of T4 to T3.

  • Dosing of iodine compounds for thyroid storm in children:

    • SSKI (50 mg iodide per drop): Neonates: 2 drops PO/NGT every 6-8 hours; Children: 2-5 drops PO/NGT every 6 hours

    • Lugol's iodine (8 mg iodine/drop): 10 drops PO/NGT every 8 hours
