Emergency use of the anti-malaria drug hydroxychloroquine as a treatment for coronavirus has been withdrawn by the US Food and Drug Administration (FDA).
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 later defended promoting the use of hydroxychloroquine as a treatment of Covid-19.
In March, the FDA granted the emergency use of the drug for some serious cases.
But on Monday, the agency said clinical studies had suggested that hydroxychloroquine was ineffective in treating the deadly virus and failed to prevent infection among those exposed to it.
