BEYFORTUS™

Active ingredient: nirsevimab


Consumer Medicine Information (CMI)

This leaflet provides important information about using BEYFORTUS. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using BEYFORTUS.

Where to find information in this leaflet:

1. Why is my child being given BEYFORTUS?

BEYFORTUS contains the active ingredient nirsevimab.

BEYFORTUS is a medicine used to protect your baby from getting respiratory syncytial virus (RSV) disease during their first RSV season. It may also be given to children less than 2 years of age who are at risk of severe RSV disease in their second RSV season.

Nirsevimab is an antibody that blocks the protein that RSV needs to infect the body and helps stops the virus from entering and infecting human cells.

RSV is a common respiratory virus that usually causes mild symptoms (cold-like illness) but can cause severe illness, including inflammation of the small airways in the lung (bronchiolitis) and pneumonia (an infection of the lungs) that may lead to hospitalisation or even death. The virus is usually more common during winter (known as the RSV season).

2. What should I know before my child is given BEYFORTUS?

Warnings

Do not use BEYFORTUS if:

  • Your child is allergic to nirsevimab, or any of the ingredients listed at the end of this leaflet.

Check with your doctor or nurse if your child:

  • has a low number of blood platelets (which help blood clotting), a bleeding problem or bruise easily or are taking a medicine to prevent blood clots (anticoagulant)

After treatment, your child may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

3. What if my child is taking other medicines?

Tell your child’s doctor, nurse or pharmacist if your child is taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

It is not expected that BEYFORTUS will be affected by other medicines or will affect how other medicines work, but tell your doctor, nurse or pharmacist about all the medicines your child is taking, regardless.

BEYFORTUS may be given at the same time as vaccines during the same visit.

4. How is BEYFORTUS given?

How and when BEYFORTUS is given

BEYFORTUS is given by a doctor, nurse or pharmacist as an injection in the muscle. It is usually given in the outer part of the thigh.

BEYFORTUS should be given before the RSV season. If your child is born during the RSV season, BEYFORTUS should be given as soon as possible after birth.

How much is given

The recommended dose is:

  • 50 mg (given as a single injection) for babies weighing less than 5 Kg and 100 mg for babies weighing 5 Kg or more in their first season.
  • 20 mg (given as 2 x 100 mg injections) for children who are vulnerable to severe RSV disease in their second RSV season

If your child is having a heart operation (cardiac surgery), he or she may be given an extra dose of BEYFORTUS after the operation.

If too much BEYFORTUS is given

As BEYFORTUS is given by a doctor or other healthcare professional, it is not likely that your child will receive too much. If necessary, your doctor can manage the situation

If you think your child has received too much BEYFORTUS you should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26), or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know after my child has been given BEYFORTUS?

    • swelling of the face, lips, tongue or throat
