What Kind of Medicine Is Casirivimab?
Put simply, Casirivimab belongs to a special group of medicines called monoclonal antibodies. When you catch an illness naturally, your body builds its own defenders called antibodies to fight off the germs. Scientists create monoclonal antibodies inside a laboratory to act as extra defenders that target the specific virus causing your infection.
Doctors often give this medicine alongside another antibody medicine to treat patients who have COVID-19 but do not yet need to be in the hospital. It is primarily prescribed for people who face a high risk of developing severe symptoms. The main goal of this medicine is to stop the virus from multiplying, prevent severe illness, and keep you out of the hospital.
It is important to know that this medicine does not have full permanent approval from health agencies like the US Food and Drug Administration. Instead, health authorities authorized its use under special emergency rules during the COVID-19 public health crisis. Doctors use it carefully when the potential benefits outweigh the known risks for eligible patients.
