Doctors embrace drug touted by Trump for Covid-19, without hard evidence it works

The decades-old drug that President Donald Trump has persistently promoted as a potential weapon against COVID-19 has within a matter of weeks become a standard of care in areas of the United States hit hard by the pandemic — though doctors prescribing it have no idea whether it works.

Doctors and pharmacists from more than half a dozen large healthcare systems in New York, Louisiana, Massachusetts, Ohio, Washington and California told Reuters they are routinely using hydroxychloroquine on patients hospitalized with COVID-19. At the same time, several said they have seen no evidence that the drug, used for years to treat malaria and autoimmune disorders, has any effect on the virus.
