The United States on Monday withdrew emergency use authorizations for
two coronavirus treatments favored by President Donald Trump, citing
their lack of efficacy and safety concerns.
“It is no longer reasonable to believe that oral formulations of HCQ
(hydroxychloroquine) and CQ (chloroquine) may be effective in treating
COVID-19,” Denise Hinton, chief scientist of the Food and Drug
Administration (FDA) wrote in a letter.
She added: “Nor is it reasonable to believe that the known and potential
benefits of these products outweigh their known and potential risk.
“Accordingly, FDA revokes the EUA for emergency use of HCQ and CQ to treat COVID-19.”
