The US Food and Drug Administration on Thursday authorized Merck’s antiviral drug, molnupiravir, to treat Covid-19.
This is the second Covid-19 antiviral pill allowed for sick people to take at home, before they become so sick that they need to be hospitalized. Merck has an agreement with the US government for the company to supply 3.1 million courses of molnupiravir under this authorization.
An FDA press release said the pill is authorized “for the treatment of mild to moderate coronavirus disease (COVID-19) in adults who have tested positive for the direct SARS-CoV-2 virus.” and those at risk of developing severe COVID-19, including hospitalization or death, and FDA-approved COVID-19 treatment options that are inaccessible or clinically inappropriate .”

Dr. Eliav Barr, Merck’s senior vice president of global health, told CNN this month that he’s optimistic that the treatment will work with the Omicron variant.
