What is Nucala?

Nucala (generic name Mepolizumab) is an injection (shot) that reduces the number of white blood cells in your blood. Too many white blood cells may cause medical problems such as swelling or inflammation in your lungs. This leads to trouble breathing or asthma attacks. Too many white blood cells may also trigger flare ups of diseases such as EPGA (eosinophilic granulomatosis with polyangiitis) or hypereosinophilic syndrome (HES).

What is Nucala used for?

Nucala (Mepolizumab) is a medicine that helps prevent serious asthma attacks in adults and children over 6 years old. You use it along with your regular asthma medications. It is not a fast-acting "rescue" inhaler so it will not stop a sudden asthma attack. It can also help reduce flares-ups in adults over age 18 with EPGA (eosinophilic granulomatosis with polyangiitis). It’s also used to treat symptoms and reduce flare-ups in adults and children 12 years of age and older with hypereosinophilic syndrome (HES).

What are the side effects of Nucala?

Serious Nucala side effects include:

  • Severe allergic reaction (including trouble breathing, or your throat swelling up). Seek medical help immediately if you get a rash or hives, or if your face, mouth, or tongue start to swell up. Go to the hospital if you feel dizzy or lightheaded, or if you have new breathing problems.
  • Shingles infections

Common Nucala side effects include:

  • headache
  • redness, pain, swelling, itching, or burning at the injection site
  • feeling tired
  • back pain

This is not a complete list of all Nucala side effects. Call your doctor if you think you are experiencing side effects to Nucala.
