Hello,

Welcome to icliniq.com.

I went through your query.

Fasenra (Benralizumab) is a newer medication used for severe eosinophilic asthma in adults. It belongs to a class of drugs called interleukin-5 (IL-5) receptor antagonists.

Eosinophils are a type of white blood cell involved in asthma inflammation, and Fasenra works by binding to the IL-5 receptor on eosinophils, leading to their elimination from the bloodstream. This reduces inflammation in the airways, which can help manage severe asthma symptoms.
When using Fasenra injection for severe eosinophilic asthma, some common side effects may include injection site reactions, headaches, and sore throat.
Serious side effects are rare but can include allergic reactions, worsening of asthma symptoms, and an increased risk of certain infections.
The duration of treatment varies from person to person. You should work with an allergologist to decide the best dose and for how long you can use it, depending on your improvement and the recurrence of the asthmatic attacks.

I hope this information will help you.

Kindly follow up if you have more concerns.

Thanks.
