Lysol and Dettol maker Reckitt Benckiser Plc has stated that “under no circumstance” should its disinfectant products be administered into the human body, through injection, ingestion or any other route.

The company issued the advice on Friday morning, after being asked whether internal administration of disinfectants “may be appropriate for investigation or use as a treatment for coronavirus”, amid recent speculation and social media activity.

On Thursday U.S. President Donald Trump had expressed interest in research presented by Bill Bryan, an undersecretary at the Department of Homeland Security on whether exposure to humidity or heat kills the virus at a faster pace. Trump had also mentioned the potential use of disinfectant for the coronavirus.

“As with all products, our disinfectant and hygiene products should only be used as intended and in line with usage guidelines,” Reckitt said in its statement on Friday.
