Patient Education

Mepolizumab Injection


Mepolizumab injection is used along with other medications to prevent wheezing, difficulty breathing, chest tightness, and coughing caused by asthma in certain children 6 years of age and older and adults whose asthma is not controlled with their current asthma medication(s). It is also used to treat eosinophilic granulomatosis with polyangiitis (EGPA; a condition that involves asthma, high levels of white blood cells, and blood vessel swelling) in adults. Mepolizumab injection is also used to treat hypereosinophilic syndrome (HES; group of blood disorders that occurs with high levels of certain white blood cells) in adults and children 12 years and older who have had this condition for 6 months or longer. Mepolizumab injection is in a class of medications called monoclonal antibodies. It works by blocking the action of a certain natural substance in the body that causes the symptoms of asthma.
