What is pemivibart?

Pemivibart is an experimental medicine being studied for the prevention of COVID-19 before being exposed to COVID-19. This drug is still being studied and all of its risks are not yet known.

Pemivibart does not replace vaccination against COVID-19.

The US Food and Drug Administration (FDA) has authorized emergency use of pemivibart for prevention of COVID-19 in adults and children at least 12 years of age who weigh at least 88 lbs (40 kg) and:

• who are not currently infected with COVID-19;

• have not had a known recent exposure to someone infected with COVID-19;

• have a weak immune system (due to a medical condition, certain medicines, or treatment); and

• for whom other COVID-19 vaccination options will not work.

Your doctor will determine if you are able to receive pemivibart.

Pemivibart is not authorized for use:

• to treat COVID-19; or

• if you are infected with COVID-19, are waiting for testing results, or are exposed to someone infected with COVID-19.

Pemivibart may also be used for purposes not listed in this medication guide.
