What is NUCALA?

NUCALA is a different kind of treatment for your severe asthma. It's an injection you get in your doctor's office once every 4 weeks. When added to your current asthma medications, NUCALA may decrease airway inflammation that may trigger severe asthma attacks.

How is NUCALA different?

  • It's not a steroid or an inhaler.
  • It targets eosinophils, one source of inflammation, so it treats more than just your symptoms of severe asthma.

What are the benefits of NUCALA?

Add NUCALA to your asthma medications to:

Prevent severe asthma attacks
Studies have proven that NUCALA significantly reduced the occurrence of severe asthma attacks by more than half, even those that led to ER visits or hospitalizations. Your results may vary.
Reduce the use of oral steroids
NUCALA is NOT a steroid, and when added to your asthma medication, it helps to reduce your use of steroids like prednisone. Your results may vary.

Did you know?

Studies also showed that NUCALA helped* improve asthma control and reduce symptoms. And in a study, people with severe asthma stated that they had a better health-related quality of life after taking NUCALA.

* Based on the limits of the studies, the results are descriptive, and your experience may or may not be the same.

Why would your doctor recommend NUCALA?

You and your doctor are treating your severe asthma, but you may not be addressing one of the underlying causes: eosinophils. Your doctor may give you a blood test that measures your eosinophil count. In clinical studies, an eosinophil count helped identify patients whose asthma was more likely to respond to treatment with NUCALA.

Based on your blood test results, your doctor may recommend adding NUCALA to your asthma treatment plan. NUCALA works with your current asthma medicines to decrease airway inflammation that can trigger severe asthma attacks.

What else should you know about NUCALA?

It's an add-on
NUCALA works in addition to the asthma medicines you already take. It's important to continue to take your current asthma medications as instructed by your healthcare provider.
It goes to a source
Eosinophils are a normal part of your immune system, but in higher numbers, they can cause inflammation. NUCALA helps reduce eosinophils in the blood, so it treats a source of severe asthma, not just the symptoms.
It works over time
NUCALA is an ongoing treatment. You may not feel immediate improvement. NUCALA can reduce inflammation, which can lead to fewer severe asthma attacks, but you may still have some attacks.

What's the next step?

NUCALA may work to help prevent your severe asthma attacks, so it's important to talk to your doctor about it.

  1. Tell your doctor everything you're doing to manage your severe asthma, and talk about how your asthma is affecting your life.
  2. Ask your doctor if adding NUCALA to your current asthma treatment could help improve your severe asthma.
  3. Ask your doctor for a blood test to check your eosinophil level.
