Palivizumab is used in certain infants and young children to prevent serious lung infections (such as pneumonia) that are caused by a certain virus (respiratory syncytial virus-RSV). Palivizumab works by preventing the growth of the virus. This medication is not used to treat RSV infection, but should be continued even if your child gets the RSV infection to prevent a more serious infection.

Read the Patient Information Leaflet if available from your health care professional before your child starts receiving palivizumab and before each injection. If you have any questions, ask your doctor or pharmacist.

This medication is given into a muscle (usually the thigh) by a health care professional as directed by your child's doctor, usually once a month during RSV season. RSV season in the northern hemisphere usually starts in October and runs through April. The dosage is based on your child's weight.

Your child should receive this medication regularly to get the most benefit from it. To help you remember, mark your calendar with a reminder.
