U.S. President Donald Trump once suggested that people should inject bleach or other disinfectants into their bodies to treat COVID-19.
During an April 2020 media briefing, Trump did ask members of the government’s coronavirus task force to look into whether disinfectants could be injected inside people to treat COVID-19. But when a reporter asked in a follow-up question whether cleaning products like bleach and isopropyl alcohol would be injected into a person, Trump said those products would be used for sterilizing an area, not for injections.
However, at no point did he explicitly tell people they could or should inject bleach into their bodies.
For years, a claim has spread online and offline that, during the coronavirus pandemic, U.S. President Donald Trump advised people to “inject bleach” into their bodies to treat COVID-19.
Following a Sept. 22, 2025, news conference at the White House, the rumor resurfaced after Trump said (archived) that taking the painkiller acetaminophen, known commercially as Tylenol and internationally as paracetamol, while pregnant “can be associated with a very increased risk of autism” in babies.
Though Trump’s comments made little sense and were ridiculed and described as dangerous by experts, under any reasonable interpretation of his words, he did not explicitly suggest people should inject themselves with bleach or other household disinfectants.
Instead, while floating the idea to the government’s coronavirus task force and the media, Trump asked whether injecting disinfectants “inside” could help fight the virus, as we further outline below. Therefore, because the social media posts making the claim since have been at best a misinterpretation and at worst a misrepresentation of what Trump said, we have rated this claim as containing mostly false information.
On April 23, 2020, Trump conducted an hourlong media briefing with members of the government’s coronavirus task force (transcript).
He spoke several times throughout the conference, but just over 26 minutes in, he took over from the head of the science and technology directorate at the Department of Homeland Security, Bill Bryan, who had just been discussing the use of ultraviolet light and disinfectants — such as bleach and isopropyl alcohol — to kill the virus rapidly on nonporous surfaces.
In an apparent reference to Bryan’s earlier comments, Trump then said (around the 26:51 mark):
Four minutes later, a journalist responded to Trump’s disinfectant comments by asking whether there was any scenario in which cleaning products like bleach and isopropyl alcohol would be injected into people.
Bryan replied first, saying: “No, I’m here to talk about the findings that we had in the study. We won’t do that within that lab, our lab.”
Trump then clarified his own remarks, adding: “It wouldn’t be through injection. We’re talking about through almost a cleaning, sterilization of an area. Maybe it works, maybe it doesn’t work. But it certainly has a big effect if it’s on a stationary object.”
At no point in the media briefing did Trump recommend that people inject bleach or other disinfectants into their bodies. He merely asked experts whether disinfectants could be injected to tackle COVID-19; a stance he later rowed back on when pressed by a journalist.
A day later, Trump told reporters in the Oval Office his question about injecting disinfectants was a “sarcastic question” to “see what would happen” (archived):
He then denied he was asking medical experts to look into injecting people with disinfectants.
Nonetheless, Trump’s comments about injecting disinfectants drew widespread criticism from experts.
Reckitt Benckiser, the Britain-based maker of cleaning, disinfectant and antiseptic products Dettol and Lysol, said in a statement (archived): “We must be clear that under no circumstance should our disinfectant products be administered into the human body (through injection, ingestion or any other route).”
John Balmes, a pulmonologist at Zuckerberg San Francisco General Hospital and a professor of medicine at the University of California San Francisco, told Bloomberg (archived) on April 24, 2020, that inhaling chlorine bleach “would be absolutely the worst thing for the lungs.”
“The airway and lungs are not made to be exposed to even an aerosol of disinfectant. … Not even a low dilution of bleach or isopropyl alcohol is safe. … It’s a totally ridiculous concept.”
Dr. Vin Gupta, a pulmonologist and global health policy expert, told NBC News that same day (archived): “This notion of injecting or ingesting any type of cleansing product into the body is irresponsible, and it’s dangerous. … It’s a common method that people utilize when they want to kill themselves.”
