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.

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

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.

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

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

NUCALA helps you gain asthma control and helps reduce your use of oral steroids like prednisone. 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.
