Who should not take potassium iodide (KI) or have restricted use?
Persons with known iodine sensitivity should avoid KI, as should individuals with dermatitis herpetiformis and hypocomplementemic vasculitis, extremely rare conditions associated with an increased risk of iodine hypersensitivity. Individuals with multinodular goiter, Graves’ disease, and autoimmune thyroiditis should be treated with caution — especially if dosing extends beyond a few days.
