How does this medication work? What will it do for me?
This combination medication contains 2 active ingredients: tixagevimab and cilgavimab. This medication belongs to the class of medications called Anti-SARS-CoV-2 spike protein monoclonal antibodies.
It is used to prevent infection with SARS-CoV-2 (COVID-19) virus for individuals 12 years and older weighing at least 40 kg, who either have a weakened immune system or for whom vaccination is not recommended. It may also be used to treat mild-to-moderate COVID-19 infection for individuals 12 years and older who weigh at least 40 kg.
When a person is infected with the COVID-19 virus, the virus attaches to healthy cells using the spike proteins. The virus then infects the healthy cell. Tixagevimab-cilgavimab works at 2 different areas on the virus spike protein to prevent the virus from attaching and infecting human cells.
