What are controller medications for asthma (long-term control)?
A controller medication is a daily medication that is used to prevent or improve asthma symptoms in patients who experience frequent symptoms. The decision to use a controller medication for a patient with asthma is based on the frequency and type of daytime or nighttime symptoms, frequency of medical visits for asthma, frequency of requiring asthma rescue medications, frequency of oral steroid use, impact of asthma symptoms on daily life, and breathing tests for asthma, which are performed in the medical office. In patients requiring controller medications, inhaled corticosteroids are generally considered as the first-line therapy for asthma.
