Fasenra (Benralizumab)

What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Prescription Required

  • Product Details


    Fasenra is a prescription asthma treatment medication given as an injection and used to treat eosinophilic asthma where activated white blood cells (eosinophils) cause inflammation of the airways into the lungs. The standard asthma attack symptoms of breathing difficulties, wheezing, and chest pain / tightness apply but the cause of the asthma is different and not related on inflammation or muscle constriction in the same way. The active ingredient in Fasenra – Benralizumab – works by binding to the interleukin-5 receptor in the eosinophils and this signals the body’s immune system to attack and eliminate those cells.
