On Oct. 22, the Food and Drug Administration (FDA) approved the first drug for treating COVID-19. Remdesivir, an antiviral medication given intravenously, is now approved for anyone hospitalized with COVID-19. It works by blocking the virus’s ability to make more copies of itself. Earlier this year, the drug had received emergency use authorization (EUA), which falls short of approval but is granted during a public health crisis if there is encouraging data supporting its potential benefits.
