Before taking this medicine

Etesevimab and bamlanivimab are not authorized for use in states or territories where certain variants of COVID-19 may be resistant to these medicines. Tell your doctor where you've lived or traveled to in the past 2 weeks.

Tell your doctor if:

  • you had a COVID-19 vaccine;

  • you have any allergy;

  • you have any serious or chronic disease; or

  • you are pregnant or breastfeeding.

COVID-19 is more likely to cause serious illness or death in a pregnant woman. Not all risks are known yet, but being treated with etesevimab and bamlanivimab is likely to be less harmful than being infected with COVID-19 during pregnancy.

How is etesevimab given?

Etesevimab and bamlanivimab are injected into a vein by healthcare provider.

These medicines are injected slowly over 21 to 70 minutes. You will be watched for a short time to make sure you do not have an allergic reaction.

Bamlanivimab with etesevimab is usually given as only one dose as soon as possible after you are exposed to or test positive for COVID-19, or within 10 days after the start of symptoms.

Being treated with etesevimab and bamlanivimab will not make you less contagious to other people. Keep using infection control methods such as self-isolation, social distancing, hand-washing, using protective face covering, disinfecting surfaces you touch a lot, and not sharing personal items with others.

These medicines also may not keep you from becoming infected with coronavirus again, and could also affect your body's immune response to a coronavirus vaccine. Etesevimab and bamlanivimab are still being studied and all of the risks are not yet known.
