What Is Nucala Used For?

Nucala is a medication that helps manage conditions associated with high levels of eosinophils, a type of white blood cell.

Primary Uses

Nucala is primarily used to treat severe eosinophilic asthma, chronic rhinosinusitis with nasal polyps, eosinophilic granulomatosis with polyangiitis (EGPA), and chronic obstructive pulmonary disease (COPD) with elevated eosinophils.

How It Works

Nucala works by blocking interleukin-5, a protein that promotes the production of eosinophils, thereby reducing their levels in the blood and lungs.

Good to know: Nucala is not addictive.
