Why is this medication prescribed?
Benralizumab injection is used in combination with other medications to treat adults and children 12 years of age and older with uncontrolled asthma who also experience wheezing, breathing difficulties, chest tightness, and coughing. The drug benralizumab injection belongs to the monoclonal antibody drug class. It functions by lowering a certain type of white blood cell to aid in reducing edema and irritability of the airways to make breathing easier.
How should this medicine be used?
Benralizumab injection is available as a solution to inject into your upper arm, thigh, or abdomen subcutaneously (just under the skin). In a medical office or healthcare facility, a doctor or nurse typically administers it. For the first three doses, it is typically administered once every 4 weeks, and after that, once every 8 weeks. Depending on your illness and how well you respond to the drug, your doctor will decide how long your therapy should last.
If your doctor has prescribed another medicine for you, do not stop taking it or reduce the dosage unless specifically instructed to do so. Your other medications’ dosages might need to be gradually reduced by your doctor.
The injection of benralizumab is not utilized to treat an asthma attack that comes on suddenly. To use during attacks, your doctor will prescribe a short-acting inhaler. Consult your doctor for advice on how to handle sudden asthma attack symptoms. Talk to your doctor if your asthma symptoms worsen or if you experience episodes more frequently.
