US President Donald Trump says he is taking hydroxychloroquine to protect against Covid-19, despite warnings that it is not effective and can damage the heart.
"I'm taking hydroxychloroquine," Trump told reporters. "I've been taking it for the last week and a half. A pill every day."
Trump volunteered the disclosure during a question-and-answer session with reporters as he met restaurant executives whose businesses are reeling from the impact of the virus.
Weeks ago Trump had promoted the drug as a potential treatment based on a positive report about its use against the virus, but subsequent studies found that it was not helpful. The Food and Drug Administration has issued a warning about its use.
In a 24 April statement, the FDA said it is "aware of reports of serious heart rhythm problems" in patients with Covid-19 treated with hydroxychloroquine or an older drug, chloroquine.
Trump, 73, who is tested daily for the virus, said he had asked the White House physician if it was okay to take the drug, and the doctor told him, "well, if you'd like it."
The president, a well-known germaphobe, has nonetheless refused to wear a protective mask in the West Wing.
Fox News Channel, immediately after Trump's remarks, interviewed Dr Bob Lahita, a professor of medicine at Rutgers University, who cautioned people not to take hydroxychloroquine.
"There's no effect that we have seen and we have treated multiple patients with it," he said.
Trump said he also took a single dose of azithromycin, an antibiotic which is meant to prevent infection. In conjunction with hydroxychloroquine, Trump said he was taking zinc.
"All I can tell you is so far I seem to be OK," Trump said.
