Asthma is a chronic lung disease very common in the United States and worldwide. The disease is characterized by a narrowing of the airways in the lungs that is treatable with various medications and avoiding environmental factors that trigger asthma attacks. When patients don’t take prescribed medications to treat their asthma the consequences can be deadly. The Centers for Disease Control and Prevention reports that in 2010 asthma accounted for 3,404 deaths, 439,400 hospitalizations, 1.8 million emergency room visits, and 14.2 million physician office visits. Drug costs are one of the main reasons people are not taking their asthma medications.
