Use of long-term control medication among persons with active asthma

Using long-term control medications daily helps prevent symptoms

Long-term control (LTC) medications help reduce airway inflammation, control chronic symptoms, and prevent asthma attacks. These medications do not relieve asthma symptoms quickly. To achieve and maintain control of asthma, most people must use LTC medications daily(EPR-3‡).

Nearly 39.0% of all adults§ and 40.2% of all children§ with self-reported active asthma used at least one kind of LTC medication in the past 3 months.
