How does NUCALA work?

What's the relationship between severe asthma, inflammation, and NUCALA? Follow these simple steps to find out how it all works.

Eosinophils [ee-uh-sin-uh-fils] are white blood cells that are a normal part of the body's immune system.11

Too many eosinophils can lead to inflammation in your lungs. Inflammation can cause severe asthma attacks.6

A simple blood test can measure the number of eosinophils in your blood. In clinical studies, this helped identify patients whose asthma was more likely to respond to treatment with NUCALA.6

Based on your test results, your doctor may add NUCALA to your asthma treatment. This asthma treatment is designed to reduce the number of eosinophils in your blood.1

Reducing the number of eosinophils in your blood can help reduce airway inflammation.5

NUCALA can help you gain asthma control and reduce the use of oral steroids like prednisone.10 NUCALA works over time, so you may not feel immediate improvement. It's important to receive your injection of NUCALA once every four weeks as prescribed, even if you're feeling better.1,2
