Palivizumab stops respiratory syncytial
virus (RSV) from reproducing. This medicine contains
antibodies that are made in a lab.
Palivizumab is used to prevent
RSV infection. It is mainly used for
children who have a high risk of developing complications, such as those who have
chronic lung disease or heart problems. If your baby
born early or has health problems, talk to your doctor
about the need to prevent RSV.
If palivizumab does not prevent a
child from becoming infected with RSV, it may make the illness less severe.
This reduces the child's chance of having complications, such as
Using palivizumab monthly during
the RSV season lowers the chance of needing to go to the hospital (for
RSV-related illnesses) by almost half, and it shortens the length of stay in
the hospital by more than half.1

fall to early spring), this shot is given once a month for up to 5 months. The number of doses depends on your child's risk factors.
Your child may need to take this medicine for most of the RSV season, whether he or she gets RSV infection or not. Different strains of RSV can be present in a community during the
same year, so treatment may still offer protection from infection.
Palivizumab does not interfere with
Medicine is one of the many tools your doctor has to treat a health problem. If your child takes medicine as your doctor suggests, it will improve your child's health and may prevent future problems. If your child doesn't take the medicines properly, his or her health (and perhaps life) may be at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
