Is it appropriate or beneficial to use a 2% povidone-iodine (Betadine) gargle for nasal symptoms, such as sneezing and a runny nose, in the absence of a throat infection?
Using a povidone-iodine (Betadine) gargle will not help your nasal symptoms. Since gargling only reaches the back of your throat, it cannot target the nasal passages where these symptoms originate. Additionally, gargle solutions are formulated differently and are not safe to use in your nose. For relief from sneezing and a runny nose, a gentle saline nasal spray or an oral antihistamine would be much more effective and safer options.
