Palivizumab is used in certain infants and young children to prevent infections of the breathing tubes and lungs that are caused by a certain virus (respiratory syncytial virus-RSV). It is known as a monoclonal antibody, and it works by preventing the growth of RSV. This medication is not used to treat RSV infection.
Read the Patient Information Leaflet provided by your doctor or pharmacist before your child starts receiving palivizumab and before each injection. If you have any questions, consult your doctor or pharmacist.
This medication is given into the muscle by a health care professional, usually once a month during RSV season or as directed by your child's doctor. Dosage is based on your child's weight, medical condition, and response to treatment.
For the most benefit from this drug, keep all scheduled medical appointments, and make sure your child receives each prescribed dose of this medication during RSV season. In the northern hemisphere, RSV season is usually November through April. Continue monthly injections even if your child has a RSV infection. Even if your child has been infected with RSV, he or she may become infected again.
A certain heart surgery (coronary artery bypass graft-CABG) can decrease the effectiveness of palivizumab. If your child has this surgery, he or she should receive the next dose of this medication as soon as possible after the surgery, even if it has been less than 1 month since the last injection.
Fever, cough, earache, runny nose, or pain/redness/swelling at the injection site may occur. If any of these effects persist or worsen, contact the doctor or pharmacist promptly.
Remember that the doctor has prescribed this medication because he or she has judged that the benefit to your child is greater than the risk of side effects. Many children using this medication do not have serious side effects.
