LINDA — Real FASENRA user and genuine patient story.

FASENRA is an add-on maintenance treatment for patients 12 and older with severe eosinophilic asthma. See more

Not for other eosinophilic conditions or sudden breathing problems.

If any of these have happened to you,
it could be a sign that you have eosinophilic asthma:

You often use a rescue inhaler to control your asthma symptoms

You’ve taken oral steroids like prednisone for your asthma

You’ve had asthma attacks that required visits to the ER or Urgent Care

You wake up at night due to asthma symptoms

In fact, nearly 7 out of 10 adults with asthma may have eosinophilic asthma.*

*2005-2006 CDC survey of 310 adults who said they had asthma and had eosinophil counts of 150 cells/μL or more.

So what is it, exactly?

Eosinophils are white blood cells, a normal part of the immune system. They can cause airway inflammation for some people with asthma, which can lead to asthma symptoms and attacks.

A simple blood test can help determine if you have eosinophilic asthma.

How can FASENRA help?

Everyone has eosinophils, but people living with eosinophilic asthma can have too many. FASENRA is designed to work with your body by attracting immune cells that remove eosinophils—a key cause of asthma.

The mechanism of action of FASENRA in asthma is not fully understood.

Since adding FASENRA, my breathing is better…

I can finally get back to doing some of the things I want to do.


Real patients talk about life on FASENRA.

If your current medications aren’t enough, consider asking about adding FASENRA.

Go beyond just managing your asthma symptoms. FASENRA is designed to target and remove eosinophils, a key cause of asthma.*

*The mechanism of action of FASENRA in asthma is not fully understood.

FASENRA has been proven to help:

Prevent asthma attacks

Improve breathing

Lower oral steroid use*

Your results may vary.

FASENRA was studied in a robust clinical trial program for severe eosinophilic asthma. FASENRA added to standard asthma treatments worked better than standard treatments alone. FASENRA is given by a healthcare provider, only once every 8 weeks after the first 2 months.

*For people taking oral steroids daily.

First 3 doses given on day 1, week 4, and week 8.

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

Before receiving FASENRA, tell your healthcare provider about all of your medical conditions, including if you:

  • are taking oral or inhaled corticosteroid medicines. Do not stop taking your corticosteroid medicines unless instructed by your healthcare provider. This may cause other symptoms that were controlled by the corticosteroid medicine to come back.
  • have a parasitic (helminth) infection.
  • are pregnant or plan to become pregnant. It is not known if FASENRA will harm your unborn baby. Tell your healthcare provider if you become pregnant during your treatment with FASENRA.
  • are breastfeeding or plan to breastfeed. It is not known if FASENRA passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby if you receive FASENRA.
  • are taking prescription and over-the-counter medicines, vitamins, or herbal supplements.

Do not stop taking your other asthma medicines unless instructed to do so by your healthcare provider.

The most common side effects of FASENRA include: headache and sore throat. These are not all the possible side effects of FASENRA.


FASENRA is a prescription medicine used with other asthma medicines for the maintenance treatment of asthma in people 12 years and older whose asthma is not controlled with their current asthma medicines. FASENRA helps prevent severe asthma attacks (exacerbations) and may improve your breathing. Medicines such as FASENRA reduce blood eosinophils. Eosinophils are a type of white blood cell that may contribute to your asthma.

FASENRA is not used to treat other problems caused by eosinophils and is not used to treat sudden breathing problems. Tell your healthcare provider if your asthma does not get better or if it gets worse after you start treatment with FASENRA.

It is not known if FASENRA is safe and effective in children under 12 years of age.
