HOW DOES NUCALA WORK?

NUCALA is not a steroid, it’s a biologic that gets to a key source of inflammation—causing your HES symptoms and flares. It is not fully understood how NUCALA works.

NUCALA gets to a key source—here are the facts:

NUCALA targets eosinophils

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

What that means for your HES: With HES, your blood eosinophil count is elevated. Elevated eosinophils in your blood can lead to inflammation.

NUCALA reduces eosinophils

NUCALA is the first approved treatment for patients with HES that targets eosinophils.

What that means for your HES: NUCALA reduces the number of eosinophils in the blood,* which reduces the inflammation causing HES symptoms and flares.
