(Reuters) - Mouthwashes with antiviral ingredients could help decrease COVID-19 transmission by reducing viral loads in the mouths of infected patients when they cough, sneeze or speak, according to a paper in the Journal of Dental Research.

Studies have found that rinses containing cetylpyridinium chloride or povidone-iodine can reduce the oral coronavirus load; other promising compounds include hydrogen peroxide, chlorhexidine, cyclodextrin, Citrox, and certain essential oils.

Coauthor Dr. Florence Carrouel of University Claude Bernard Lyon in France told Reuters everyone should be using these mouthwashes because people can be infected and not realize it.

While more studies are needed to determine appropriate regimens, she suggests using three doses of antiviral mouthwash the day before a meeting, and one dose the morning of the event. COVID-19 patients should be using mouthwash regularly for seven to 10 days.
