Preliminary laboratory research conducted by Dr. HSJ Institute of Dental Sciences, Panjab University in collaboration with CSIR-Institute of Microbial Technology revealed that one of the most routinely used oral rinses, chlorhexidine, has been shown to be effective against Covid- 19.

The study, titled “Chlorhexidine: An Effective Anti-Covid Oral Rinse” was supported by Hyderabad Headquarters Dr. Reddy’s Laboratories and Design Innovation Center, Panjab University.

Studies have shown that the Covid-19 virus colonizes in the oral and nasal cavities. Mouth rinses can be an effective way to reduce colonization and possibly reduce the transmission of infection.

Mouth rinsing with chlorhexidine digluconate at a concentration of 0.2% has been observed to kill more than 99.9% of the Covid-19 virus in a minimum contact time of 30 seconds.

“Chlorhexidine killed the coronavirus within 30 seconds of exposure in the laboratory. These are the first results of laboratory studies and need to be verified through clinical trials, ” said Dr. Ashish Jain of Dr. HSJ Institute of Dental Sciences.

This study was intended to provide an overview of the effectiveness of chlorhexidine 0.2 percent against Covid-19 through analysis in a laboratory.
