FDA Revokes Emergency Use Authorization for Hydroxychloroquine and Chloroquine as COVID-19 Treatments

The U.S. Food and Drug Administration on Monday revoked its emergency use authorization (EUA) for chloroquine phosphate and hydroxychloroquine sulfate to be used as treatments for COVID-19. FDA Chief Scientist Denise M. Hinton wrote that the evidence does not reasonably suggest that the drugs are effective, and asserted that their potential benefits don't outweigh their known health risks.
