OverviewTOP
Palivizumab injection is used to prevent serious lung infection in children and babies caused by respiratory syncytial virus (RSV). It belongs to a group of medicines known as immunizing agents. This medicine works by giving your body antibodies to protect it against RSV infection.
RSV infection can cause serious problems that affect the lungs, such as pneumonia and bronchitis, and in severe cases can even cause death. These problems are more likely to occur in infants and children younger than 6 months of age with chronic lung disease and breathing problems. Babies who were born premature or babies who were born with heart disease may also have problems with RSV.
The onset of RSV activity usually occurs in November and continues through April, but it may begin earlier or continue later in certain communities. A good way to help prevent RSV infection is to receive palivizumab before the start of the RSV season.
This medicine is to be given only by or under the direct supervision of your doctor.
