What the medication is used for

Sotrovimab is a medicine being studied to prevent worsening of COVID-19. Sotrovimab may be given if you or your child are 12 years of age or older and weigh at least 40 kg (kilograms) and are not already in the hospital. Sotrovimab is only given to patients at high risk of being hospitalized or dying due to COVID-19, because of their age or medical conditions.

Sotrovimab is not authorized for use in patients:

  • who are in the hospital to treat their COVID-19, OR
  • who are given oxygen to help them breathe because of COVID-19.
What it does

COVID-19 is caused by a coronavirus (SARS-CoV-2). You can get COVID 19 through contact with another person who has the virus.

Sotrovimab is a monoclonal antibody, a type of protein that attaches to the spike protein of the coronavirus (SARS-CoV-2) that causes COVID-19, and prevents the virus from entering and infecting healthy cells within your body. Sotrovimab may help reduce your risk of progressing from mild or moderate COVID-19 to severe infection that requires hospitalization.
