What side effects can patients expect with Fasenra (benralizumab)?
Fasenra (benralizumab) is an injection used for severe eosinophilic asthma. Commonly reported side effects include injection-site reactions (such as redness, swelling, itching, or pain where the shot is given) and headache. Some patients also report fatigue.
What “serious” side effects are patients told to watch for?
With Fasenra, the main serious risks to monitor for are allergic reactions. Patients are typically advised to seek urgent care if they develop symptoms such as trouble breathing, swelling of the face or throat, widespread rash, or severe dizziness after an injection.
How soon do side effects happen after a dose?
Injection-site reactions and headache can occur shortly after dosing. Allergic reaction symptoms can also happen soon after the shot, which is why patients are commonly monitored after administration and instructed on when to call for help.
Who is most at risk for side effects?
People with a history of drug allergies may be more prone to allergic reactions. Risk also depends on other conditions and medications, and on how frequently the patient is treated.
Are there differences in side effects compared with other asthma biologics?
Side-effect patterns among biologic asthma treatments overlap, with allergic reactions and injection-site reactions being the major shared concerns. The exact frequency of specific events can differ by product, and label details should be used for the best comparison.
What should patients do if they have side effects?
If side effects are mild (like minor injection-site discomfort), patients often manage them while continuing treatment if their clinician agrees. For signs of an allergic reaction or any severe or worsening symptoms, patients should stop and seek urgent medical care.
