The US Food and Drug Administration has withdrawn the emergency use of the anti-malaria drug hydroxychloroquine as a treatment for coronavirus. The FDA said that new evidence from clinical trials meant that it was no longer reasonable to believe that the drug would produce an antiviral effect. President Donald Trump defended promoting the use of hydroxychloroquine after dosing himself with the drug when White House staffers were infected.
