Synagis is a medicine that helps prevent serious lung infections caused by respiratory syncytial virus (RSV). RSV is highly contagious. It is spread by contact with infected fluids from the nose or mouth and through droplets in the air from coughing. RSV usually occurs in the wintertime.
Usually, RSV causes mild symptoms, such as a runny nose and fever. But premature babies or those with lung or heart problems have a higher risk of getting very sick if they catch RSV.
This medicine is given only to children under 2 years old at high risk for serious complications if they should get RSV. These children include:
This medicine is not a treatment for children who already have RSV. Synagis is given by injection into the leg muscle. Synagis may be given with other routine immunizations. Multiple doses may be needed to fully protect the infant.
Synagis is an antibody that is used to prevent infection. Full-term babies get virus-fighting substances called antibodies from their mothers during pregnancy. These antibodies help to fight RSV and other viruses. But babies born prematurely often do not get enough of these antibodies before birth.
