How to take FIRAZYR

How to take FIRAZYR

  • You or your child’s first injection of FIRAZYR should be given under the guidance of a healthcare professional. Your healthcare professional will tell you when it is safe to go home.
  • You or your caregiver may inject FIRAZYR only after receiving training on how to use it. A healthcare professional will teach you and your caregiver how to use it.
  • Self-injection for children is not recommended. FIRAZYR should only be given to children by a healthcare professional or caregiver.
  • Adolescents may only self-inject if their doctor and caregiver agree that it is appropriate for them to do so.
  • Always use FIRAZYR exactly as your healthcare professional has shown you.
  • Be sure to use each FIRAZYR prefilled syringe only once, even if there is still medicine in it.
  • FIRAZYR is given as a single injection under the skin on the stomach. This is called a subcutaneous injection.
    • In adults and adolescents who weigh more than 65 kg:
      • The FIRAZYR prefilled syringe will be used to give the injection.
    • In adolescents who weigh 65 kg or less and children aged 2 years and above:
      • Some FIRAZYR will need to be transferred from the prefilled syringe into an empty graduated syringe. This graduated syringe will then be used to inject FIRAZYR.

These instructions are not meant to take the place of training by a healthcare professional. A healthcare professional will teach you and your caregiver how to give FIRAZYR. Ask your healthcare professional any questions you may have. Do not attempt to inject FIRAZYR until you are sure how to and your doctor has determined that it is appropriate for you to do so.

Know your treatment action plan

You and your HCP should also agree to a treatment plan that describes the circumstances of an HAE attack for which it is appropriate to self-inject FIRAZYR.

Make sure you are familiar with this plan and understand the signs and symptoms of an attack.
