FASENRA for Severe Eosinophilic Asthma

For adults and children ages 12 and older with severe eosinophilic asthma, FASENRA may help reduce the frequency and severity of asthma attacks. As an add-on maintenance treatment, this may be added to your current treatment plan to better manage severe asthma. Here, we’ll cover the main questions that patients ask and its benefits for severe eosinophilic asthma. 

What Is Severe Eosinophilic Asthma?

Eosinophils are the main cause of asthma for many adults. Eosinophils are white blood cells that play a role in immune function. However, these cells can also cause lung inflammation in some individuals and have the potential to trigger asthma symptoms. 


Eosinophilic asthma presents multiple health risks, including a greater potential for asthma attacks in the future, compromised lung function, and frequent administration of oral steroids. Repeatedly taking oral steroids can cause a reliance on them, but FASENRA can help to counteract it. 


It is different from other asthma treatments because it’s designed to supplement the asthma medications already prescribed to you. Also, it’s neither an inhaler nor a steroid. Instead, it is an injection administered by your trained healthcare provider. Injections are given every eight weeks after the first two weeks of treatment, during which three doses are administered on day one, week four, and week eight. 

How Does FASENRA Work?

It is formulated to target eosinophils to reduce the severity and frequency of asthma attacks. By lessening lung inflammation caused by eosinophils, it may also facilitate breathing for individuals with severe eosinophilic asthma. It works to reduce eosinophils in the blood to cut down on its impact on lung function. 


FASENRA is taken alongside your already prescribed asthma treatments. You won’t stop taking the medications that are already included in your treatment plan, but it will work as a supplement to fight inflammation from eosinophils.

What Are the Benefits of FASENRA?

It may provide multiple benefits for adults and children over 12 suffering from severe eosinophilic asthma, including:


  • Lessening asthma attack frequency by as much as 51 percent
  • Facilitating easier breathing by improving lung function
  • Reducing oral steroid use by up to 75 percent
  • Potentially eliminating the need to take oral steroids for asthma symptoms


FASENRA is the top add-on treatment for asthma patients who are just starting the medication to reduce eosinophils. If you suffer from severe eosinophilic asthma, this may help you more effectively manage your symptoms, breathe easier, and have fewer asthma attacks. Contact your doctor to see if this may be the right treatment option for you.
