Why you shouldn’t gargle Betadine to combat COVID-19, according to experts

In addition to the risks of swallowing Betadine, there are risks to inhaling it, says¬†Andrew Noymer, M.D., an associate professor of population health and disease prevention and public health at the University of California Irvine. “I do worry, in particular, about people misting povidone-iodine into their nasal passages,” says Dr. Noymer. “The sinuses are close to the brain, and I worry about the migration of iodine into the central nervous system…please don’t go putting chemicals up into the nasal and sinus passages that don’t belong there.”
