IMPORTANT SAFETY INFORMATION

Your child should not take Beyfortus if your child has a history of serious allergic reactions to nirsevimab-alip or any of the ingredients in Beyfortus.

Before your child receives Beyfortus, tell your healthcare provider about all of your child’s medical conditions, including if your child:

  • has ever had a reaction to Beyfortus.

  • has bleeding or bruising problems. If your child has a problem with bleeding or bruises easily, an injection could cause a problem.


Tell your healthcare provider about all the medicines your child takes, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Your infant should not receive a medicine called palivizumab if they have already received Beyfortus in the same RSV season.

Serious allergic reactions have happened with Beyfortus. Get medical help right away if your child has any of the following signs or symptoms of a serious allergic reaction:

  • swelling of the face, mouth, or tongue

  • difficulty swallowing or breathing

  • unresponsiveness

  • bluish color of skin, lips, or under fingernails

  • muscle weakness

  • severe rash, hives, or itching


The most common side effects of Beyfortus include rash and pain, swelling, or hardness at the site of your child’s injection. These are not all the possible side effects of Beyfortus. Call your healthcare provider if you have questions about side effects.
