Benralizumab injection is used along with other medications to prevent wheezing, difficulty breathing, chest tightness, and coughing caused by asthma in adults and children 12 years and older whose asthma is not controlled with their current asthma medication. Benralizumab injection is in a class of medications called monoclonal antibodies. It works by reducing a certain type of white blood cell to help decrease swelling and irritation of the airways to allow for easier breathing.
HOW should this medicine be used?
Benralizumab injection comes as a solution to inject subcutaneously (just under the skin) into your upper arm, thigh, or abdomen. It is usually given by a doctor or nurse in a doctor's office or healthcare facility. It is usually given once every 4 weeks for the first 3 doses, then given once every 8 weeks. Your doctor will determine the length of your treatment based on your condition and how well you respond to the medication.
Do not decrease your dose of any other asthma medication or stop taking any other medication that has been prescribed by your doctor unless your doctor tells you to do so. Your doctor may want to decrease the doses of your other medications gradually.
Benralizumab injection is not used to treat a sudden attack of asthma symptoms. Your doctor will prescribe a short-acting inhaler to use during attacks. Talk to your doctor about how to treat symptoms of a sudden asthma attack. If your asthma symptoms get worse or if you have asthma attacks more often, be sure to talk to your doctor.
