Fasenra: Use & side effects

FASENRA is an add-on maintenance treatment for patients 12 and older with severe eosinophilic asthma. It’s not used for other eosinophilic conditions or sudden breathing problems.

Nearly 7 out of 10 adults with asthma may have eosinophilic asthma. Signs of eosinophilic asthma include:

  • You often use a rescue inhaler to control your asthma symptoms.
  • You’ve had asthma attacks that required visits to the ER or Urgent Care.
  • You’ve taken oral steroids like prednisone for your asthma.
  • You wake up at night due to asthma symptoms.

FASENRA is designed to target cells in your body called eosinophils (e-o-SIN-o-phils), which can be a key cause of asthma. It can help improve breathing and prevent attacks.

When added to current asthma treatments, FASENRA has been clinically proven to help reduce the occurrence of asthma attacks by up to 51% and improve lung function.

The majority of physicians and patients preferred an 8-week dosing schedule compared to 2- and 4-week dosing.§

You can choose to get the injection at your doctor’s office, or self-administer using the FASENRA Pen as long as your doctor has shown you how to do it.

FASENRA may cause serious side effects, including:

  • allergic (hypersensitivity) reactions, including anaphylaxis. Serious allergic reactions can happen after you get your FASENRA injection. Allergic reactions can sometimes happen hours or days after you get your injection. Tell your healthcare provider or get emergency help right away if you have any of the following symptoms of an allergic reaction:
    • swelling of your face, mouth and tongue
    • breathing problems
    • fainting, dizziness, feeling lightheaded (low blood pressure)
    • rash
    • hives

Do not use FASENRA if you are allergic to benralizumab or any of the ingredients in FASENRA.

Do not use to treat sudden breathing problems.
