Gabe Kelen, M.D., director of CEPAR and head of the Johns Hopkins Department of Emergency Medicine, cautions that taking the medicine could result in serious side effects, especially in those with iodine and shellfish allergies, certain skin disorders, renal disease and thyroid problems.
Potassium iodide is a nonprescription drug that can be used to protect the thyroid gland from high radiation levels in settings of potential acute exposure, but it does not protect other parts of the body.
CEPAR experts note that harmful levels of radiation are not expected in the United States as a result of the nuclear crisis in Japan, and thus, taking the medication as a preventive measure is wholly unnecessary.
CEPAR has experts available to comment on major disasters, such as medical response in the field and emergency preparedness.
