Eosinophils [ee-uh-sin-uh-fils] are white blood cells that are a normal part of the body’s immune system.
When you have HES, your blood eosinophil count is elevated. Elevated eosinophils in your blood can lead to inflammation.
NUCALA is not a steroid like prednisone. It is the first approved treatment for patients with HES that targets eosinophils.
It is not fully understood how NUCALA works.
If you want to receive your NUCALA injections from your healthcare professional, you can have NUCALA administered in the office.
It is important to monitor for serious allergic reactions after injection, either in the office or at home. Sometimes serious allergic reactions, including anaphylaxis, can occur hours or days after administration of NUCALA. See risks and side effects.
