What is benralizumab?

Benralizumab 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.

Benralizumab is used together with other medicines to help control severe asthma in adults and children who are at least 12 years old. Benralizumab is for people whose asthma is not well controlled with other medications.

Benralizumab may also be used for purposes not listed in this medication guide.

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

  • 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.

How is benralizumab given?

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

Benralizumab is injected under the skin. A healthcare provider will give you this injection, usually once every 4 weeks at first and then once every 8 weeks.

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.

Benralizumab 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 benralizumab.

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.
