The pill was conditionally authorised for adults 18 and over on Thursday
Britain is now the first country in the world to approve the COVID-19 antiviral pill.
Developed by U.S. companies Merck and Ridgeback Biotherapeutics, the drug is aimed at those with mild to moderate COVID-19.
Patients need to also be more susceptible to developing severe illness by having at least one factor that puts them at a higher risk such as obesity, heart disease or older age diabetes.
The anti-viral medication is to be administered soon after being diagnosed with COVID and less than 5 days after symptoms begin.
This comes as Britain faces yet another wave with daily cases reaching around 40,000.
Meanwhile, U-S advisers will soon meet to vote on whether the drug should also be authorised within America.
