Uses

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.

How To Use

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 November 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 the days on a calendar when your child should receive the medication.

Side Effects

Fever or pain/redness/swelling at the injection site may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because the doctor has judged that the benefit to your child is greater than the risk of side effects. Many people using this medication do not have serious side effects.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:
