The Food and Drug Administration (FDA) has revoked its authorization of the use of hydroxychloroquine as an emergency treatment for COVID-19, the illness caused by the novel coronavirus.
As CNBC reported, back in March the agency enacted an Emergency Use Authorization (EUA) that allowed doctors to prescribe the anti-malaria drugs hydroxychloroquine and its cousin, chloroquine, off-label, to treat COVID-19. An EUA allows doctors to prescribe a drug for a use for which the agency had not previously fully approved it through regular processes.
However, after 3 months of having been approved for off-label use, the FDA has withdrawn that approval, citing its lack of efficacy.
“[The drugs are] unlikely to be effective in treating COVID-19 for the authorized uses in the EUA,” the agency said.
Further, the agency noted that side-effects associated with the drug make it too risky to use in treating COVID-19.
