Bupleurum Overview

Palivizumab Overview
-
Palivizumab injection is used to help prevent respiratory syncytial virus (RSV; common virus that can cause serious lung infections) in children less than 24 months old who are at high risk for getting RSV. Children at high risk for RSV include those who were born prematurely or have certain heart or lung diseases. Palivizumab injection is not used to treat the symptoms of RSV disease once a child already has it. Palivizumab injection is in a class of medications called monoclonal antibodies. It works by helping the immune system to slow or stop the spread of the virus in the body.
