1. What Synagis is and what it is used for

Synagis contains an active ingredient called palivizumab which is an antibody that works specifically against a virus called respiratory syncytial virus, RSV.

Your child is at high risk of getting an illness caused by a virus called respiratory syncytial virus (RSV).

Children who are more likely to get severe RSV disease (high-risk children) include babies born prematurely (35 weeks or less) or babies born with certain heart or lung problems.

Synagis is a medicine to help protect your child from getting severe RSV illness.

2. What you need to know before Synagis is given to your child

Your child should not be given Synagis

If he/she is allergic to palivizumab or any of the other ingredients of this medicine (listed in section 6). Signs and symptoms of a severe allergic reaction include:

  • severe rash, hives, or itching skin
  • swelling of the lips, tongue, or face
  • closing of the throat, difficulty swallowing
  • difficult, rapid, or irregular breathing
  • bluish colour of skin, lips, or under fingernails
  • muscle weakness or floppiness
  • a drop in blood pressure
  • unresponsiveness

Warnings and precautions

Take special care with Synagis

  • if your child is unwell. Please tell your doctor if your child is unwell, as the use of Synagis may need to be delayed.
  • if your child has any bleeding disorders as Synagis is usually injected into the thigh.

Other medicines and Synagis

Synagis is not known to interact with other medicines. However, you should inform your doctor of all medicines your child is currently taking before starting Synagis.

3. How will my child receive Synagis

How often will Synagis be given to my child?

Synagis should be given to your child at a dose of 15 mg/kg body weight once a month for as long as the risk of RSV infection remains. For your child’s best protection, it is necessary to take the doctor’s advice about when to return for additional doses of Synagis.

If your child is to have a heart operation (cardiac bypass surgery), he or she may be given an extra dose of Synagis after the operation. Your child can then go back to the original planned injections.

How will my child receive Synagis?

Synagis will be given by injection to your child into a muscle, usually in the outer part of the thigh.

What should you do if your child misses an injection of Synagis?

If your child misses an injection, you should contact your doctor as soon as possible. Each injection of Synagis can only help protect your child for about one month before another injection is needed.

Always use this medicine exactly as your doctor or pharmacist has told you. If you are not sure about how this product will be given to your child, ask your doctor or pharmacist.
