The usual recommended dose is 15 mg per kilogram of body weight, based on the child's body weight. It is given as an injection into a muscle (usually the thigh muscle) once a month during the RSV season (i.e., the times of the year when the risk of RSV is high in your community).
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
The RSV season often starts in the fall and continues until spring, although it can also occur at other times of the year. If possible, the first injection should be given before the RSV season starts. The injection will be given by a qualified health care professional.
It is important that Synagis (Palivizumab) be given exactly as recommended by your doctor. If your child misses an appointment to receive Synagis (Palivizumab), contact your doctor as soon as possible to reschedule your appointment. Each injection protects your child for about one month, so it is important to continue regular monthly injections during the RSV season, as recommended by your doctor.
If you are responsible for bringing Synagis (Palivizumab) to the appointment, store this medication in the refrigerator, do not freeze, and keep out of the reach of children.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
