What is Fasenra?

Fasenra is a monoclonal antibody that affects the actions of the body’s immune system. Benralizumab works by reducing levels of eosinophils, a certain type of white blood cell that may contribute to the symptoms of asthma.

Fasenra injection is a prescription medicine used together with other asthma medicines to help control  severe asthma  in adults and children who are at least 12 years old.

Fasenra is for people whose asthma is not well controlled with other medications.

Warnings

Before you receive Fasenra, tell your doctor about all your medical conditions or  allergies , all medicines you use, and if you are pregnant or breast-feeding.

Before taking this medicine

You should not be treated with Fasenra if you are allergic to benralizumab.

  • a parasite infection (such as roundworms or tapeworms); or
  • if you use an oral or inhaled steroid medication.

Follow your doctor’s instructions about receiving this medicine if you are pregnant. Not treating asthma during pregnancy could harm both mother and baby. Tell your doctor if you are pregnant or plan to become pregnant.

It may not be safe to breast-feed a baby while you are using this medicine. Ask your doctor about any risks.

Fasenra should not be given to a child younger than 12 years old.

How is Fasenra given?

Before you start treatment with Fasenra, your doctor may perform tests to measure your eosinophil levels.

Fasenra is injected under your skin (subcutaneously) one time every 4 weeks for the first 3 doses, and then every 8 weeks.

Fasenra comes in a single dose prefilled syringe and in a single dose autoinjector.

A healthcare provider will inject Fasenra using the single-dose prefilled syringe.

If your healthcare provider decides that you or a caregiver can give the injection of Fasenra, you or your caregiver should receive training on the right way to prepare and give the injection using the Fasenra Pen autoinjector.

Follow your doctor’s dosing instructions very carefully.

If you’ve been using a steroid medication, do not stop using it unless your doctor tells you to.

Fasenra is not a rescue medicine for asthma attacks. Use only fast-acting inhalation medicine for an attack. Seek medical attention if your fast-acting medicine does not work.

You may need frequent medical tests to help your doctor determine how long to treat you with Fasenra.

Asthma is often treated with a combination of drugs. Use all medications as directed and read all medication guides. Do not change your dose or dosing schedule without your doctor’s advice. Your dose needs may change due to surgery, illness,  stress , or a recent asthma attack. Tell your doctor if any of your medicines seem to stop working.
