What Is Synagis?

If your child is premature or has certain types of lung or heart disease, your healthcare provider may prescribe Synagis® (palivizumab). But what is Synagis and how does it work?
 
This medication is given to infants and children age 24 months and younger who have a high risk for developing serious complications with respiratory syncytial virus (RSV), a respiratory tract illness. Synagis works by binding to RSV, preventing the virus from multiplying. This drug cannot prevent RSV infection, but it can help prevent the infection from becoming severe enough to cause serious problems.
 
Synagis comes as an injection that is given once a month during RSV season, which is normally from November to April.
