What is Beyfortus

Beyfortus is a medication administered as an injection to protect babies and children under 2 years old from therespiratory syncytial virus (RSV).RSV is a common respiratory virus that generally causes mild symptoms comparable to the common cold.However, especially in babies, vulnerable children, and older adults, RSV can cause severe diseases, such as bronchiolitis (inflammation of the small airways in the lung) and pneumonia (lung infection) that can lead to hospitalization or even death.The virus is usually more common during winter.

Beyfortus contains the active ingredient nirsevimab, which is a monoclonal antibody (a protein designed to bind to a specific target) that binds to the protein that RSV needs to infect the body.By binding to this protein, Beyfortus blocks its action, thereby preventing the virus from entering and infecting human cells.

How is Beyfortus used

Beyfortus is a medication used to protect your child from RSV disease.

Your child should not use Beyfortus if they are allergic to nirsevimab or any of the other components of this medication (listed in section 6).

Inform your child's doctor, pharmacist, or nurse if this applies to your child. If you are unsure, consult with your child's doctor, pharmacist, or nurse before administering the medication.

If your child shows signs of a severe allergic reaction,contact your child's doctor immediately.

Warnings and precautions

Consult your doctor or seek immediate medical help if you observe any sign ofallergic reaction, such as:

• difficulty breathing or swallowing
• swelling of the face, lips, tongue, or throat
• severe itching on the skin, with a red rash or raised bumps

Consult with your healthcare professional before administering Beyfortus to your child if they have a low platelet count in the blood (which helps with blood clotting), a bleeding disorder, or if they are prone to easy bruising or are taking an anticoagulant (a medication to prevent blood clots).

In certain chronic diseases, where too many proteins are lost through the urine or intestines, for example, nephrotic syndrome and chronic liver disease, the level of protection provided by Beyfortus may be reduced.

Beyfortus contains 0.1 mg of polisorbate 80 in each 50 mg dose (0.5 ml) and 0.2 mg in each 100 mg dose (1 ml). Polisorbates may cause allergic reactions. Inform your doctor if your child has any known allergies.

Children and adolescents

Do not administer this medication to children between 2 and 18 years of age because it has not been studied in this group.

Other medications and Beyfortus

No interactions with other medications have been observed. However, inform your doctor, pharmacist, or nurse if your child is taking, has taken recently, or may need to take any other medication.

Beyfortus can be administered at the same time as vaccines that are part of the national vaccination program.

Beyfortus must be administered by a healthcare professional as an injection into the muscle. Normally, it is administered in the outer part of the thigh.

The recommended dose is:

• 50 mg for children who weigh less than 5 kg and 100 mg for children who weigh 5 kg or more in their first VRS season.
• 200 mg for children who remain vulnerable to severe disease by VRS in their second VRS season (administered as 2 injections of 100 mg in separate sites).

Beyfortus must be administered before the VRS season. The virus is usually more common during winter (known as the VRS season). If your child is born during winter, Beyfortus must be administered after birth.

If your child is to undergo cardiac surgery, they may be administered an additional dose of Beyfortus after the surgery to ensure adequate protection for the remainder of the VRS season.

If you have any other questions about the use of this medication, ask your doctor, pharmacist, or nurse.
