Complete patient guide for uses, dosage, side effects, and safety information
Quick Facts
What Is Fasenra Pen Used For?
Fasenra Pen is a medication that contains benralizumab, which is used to manage specific types of asthma and a condition known as eosinophilic granulomatosis with polyangiitis (EGPA).
Primary Uses
Fasenra Pen is primarily used to treat eosinophilic asthma in adults and adolescents aged 12 years and older, and EGPA in adults aged 18 years and older.
How It Works
Benralizumab works by binding to the interleukin-5 receptor on eosinophils, reducing their levels in the blood and tissues, which helps to decrease inflammation associated with asthma and EGPA.
Good to know: Fasenra Pen is not addictive.
