Bamlanivimab and etesevimab injection is currently being studied for the treatment and prevention of coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus.
Only limited clinical trial information is available at this time to support the use of bamlanivimab and etesevimab injection for the treatment of COVID-19. More information is needed to know how well the combination of bamlanivimab and etesevimab work for the treatment and prevention of COVID-19 and the possible adverse events from it.
Bamlanivimab and etesevimab injection has not undergone the standard review to be approved by the FDA for use. However, the FDA has approved an Emergency Use Authorization (EUA) to allow certain non-hospitalized adults and children and in hospitalized or non-hospitalized children and infants less than 2 years of age who have mild to moderate COVID-19 symptoms to receive bamlanivimab and etesevimab injection.
On January 24, 2022, FDA reissued the emergency use authorization (EUA) for bamlanivimab and etesevimab stating that the combination regimen is not authorized for treatment of mild to moderate COVID-19 in geographic regions where infection is likely to have been caused by a non-susceptible SARS-CoV-2 variant based on available information including variant susceptibility to these drugs and regional variant frequency. Given the prevalence of the Omicron variant in the United States, bamlanivimab and etesevimab is not recommended for use anywhere for mild to moderate disease at the present time.
Why is this medicine prescribed?
Bamlanivimab and etesevimab injection is used in certain non-hospitalized adults, children, and infants including newborns, and who have certain medical conditions that make them at higher risk for developing severe COVID-19 symptoms, including hospitalization or death:

- to prevent COVID-19 in those who are not fully vaccinated against COVID-19 or who are vaccinated, but have a weakened immune system, or are taking a medication that affects the immune system and who have had close contact or are at high risk of close contact to someone who is infected with the SARS-CoV-2 virus (for example, nursing homes, prisons).
Bamlanivimab and etesevimab is also used to treat mild to moderate symptoms of COVID-19 in hospitalized children and infants less than 2 years of age, including newborns.
Bamlanivimab and etesevimab are in a class called monoclonal antibodies. These medications work by blocking the action of a certain natural substance in the body to stop the spread of the virus.
