What drug interactions does Fasenra (benralizumab) have?
Fasenra is a monoclonal antibody that binds the IL‑5 receptor on eosinophils and affects immune cells rather than being metabolized by typical liver drug-enzyme pathways. Because of that, it has a different interaction profile than small-molecule medicines. Most interaction concerns for Fasenra are about overlaps with other immune-modifying therapies rather than classic “pharmacokinetic” drug-drug interactions.
Can you take Fasenra with asthma medicines (inhalers, steroids)?
People using Fasenra are often also on standard asthma controller regimens such as inhaled corticosteroids and sometimes oral corticosteroids. The key interaction-type issue is steroid management: as asthma improves on biologic therapy, clinicians may reduce steroid dose, but this is a supervised process. Don’t stop or reduce systemic steroids on your own because adrenal suppression and loss of asthma control can occur.
Does Fasenra interact with other biologics or immune therapies?
The main practical concern is combining multiple therapies that modulate immune function. If you are taking another biologic (for example, another asthma biologic) or an immunosuppressive medication, discuss it with your clinician before starting Fasenra so they can check whether the combination is appropriate for your condition and monitor closely.
Are vaccines affected while on Fasenra?
Immune-modifying drugs often change how clinicians think about vaccination timing, especially with live vaccines. If you need any vaccine (including live vaccines), ask your prescriber about timing relative to Fasenra dosing.
What infections should prompt caution with Fasenra?
Because Fasenra targets pathways involved in eosinophil activity, clinicians still monitor for infections and watch for worsening symptoms. If you develop signs of infection (fever, worsening respiratory symptoms, or other concerning symptoms), contact your care team rather than assuming it’s unrelated.
