Enovid is an anti-viral nasal spray device that creates a protective mechanical and chemical barrier against viruses within the nasal cavity. It contains easy-to-deliver doses of spray that lay down a barrier of nitric oxide designed to kill 99% of airborne viruses within 24 hours of treatment. Blocking entry of the COVID-19 virus via the upper respiratory tract has proven to be highly effective in preventing infection by the virus and reducing COVID-19 hospitalizations.
