Key points about Evusheld
- Evusheld contains 2 medicines – tixagevimab and cilgavimab.
- It is no longer recommended for COVID-19.
- Find out more about Evusheld, when it is used and possible side effects.
Evusheld contains 2 medicines – tixagevimab and cilgavimab. They belong to a group of medicines called monoclonal antibodies. They work by binding to the virus that causes COVID-19 infection (SARS-CoV-2) and preventing it from infecting healthy cells in your body.
The medicine is for people who have trouble making antibodies to fight disease, eg, if you have a weakened immune system (immunocompromised). Evusheld is best used before you get COVID-19. Your doctor will decide whether you need it or not. Read more about the access criteria for Evusheld.(external link)
Evusheld is not a vaccine, but consists of synthetic antibodies (made in the laboratory) which help to support your immune system to fight off infection.
Vaccines are different. They rely on your body to produce its own antibodies to prepare for being exposed to a particular virus. If you are exposed, your body will recognize it and know how to fight it off. For most people, vaccination is recommended as the best way to protect yourself against COVID-19.
Evusheld is given as 2 injections one after the other into a muscle (usually 1 injection into each of your buttocks). The injections will be administered by a doctor or nurse in a healthcare setting. Some people can have an allergic reaction to Evusheld, so you will be observed by the nurse or doctor for a short period after your injection.
Before you are given Evusheld, tell your healthcare provider if you have:
- low numbers of blood platelets (thrombocytopenia)
- had a heart attack or stroke, or other heart problems, or are at high-risk of cardiac (heart) events
- a bleeding disorder or are taking medicine to prevent blood clots
- any allergies to medicines
- any symptoms of COVID-19.
Sometimes a medicine isn’t suitable for a person with certain conditions or taking other medicines, or it can only be used with extra care. Your healthcare provider will give you more information about this.
If you are pregnant, breastfeeding or are planning to have a baby soon
There isn't a lot of research on the impact of Evusheld on pregnancy and breastfeeding. If you are pregnant, planning a pregnancy or breastfeeding, talk to your doctor about the potential risks and benefits.
If you have already had a COVID-19 vaccine
If you have received a COVID-19 vaccine, tell your healthcare provider before using Evusheld. It's possible that Evusheld may reduce your body’s immune response to a COVID-19 vaccine so you will need to have a gap of 2 weeks after your vaccination before receiving Evusheld.
As Evusheld is a new medicine, it's possible that we do not know all of the side effects yet.
