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.
Percentage of Adults with Active Asthma Who Used LTC Medications
Percentage of Children with Active Asthma Who Used LTC Medications
The percentage of people with asthma who used LTC medications varied by state. Percentages of adults ranged from 31.8% in Mississippi to 47.2% in North Dakota. Percentages of children ranged from 25.4% in Oregon to 53.2% in Mississippi.
