Words used and explanations given in the health-care setting should be selected carefully, and should be used in the context of the patient’s understanding as these can influence beliefs about asthma, sometimes in unforeseen ways. For example control medications are defined as those treating underlying inflammation. Therefore, many physicians call these controller medications or long-term controller medications. However, when having an asthma attack, patients reach for the medication that is most likely to control wheezing, cough, and shortness of breath. Many patients understand that controller medications control symptoms, not inflammation. The unintended result is that patients may use the wrong medication during attacks, get no immediate relief, and therefore believe that the medication is not working. Similar problems are encountered with the what are called preventer medications. Inhaled corticosteroids (ICSs), for example, prevent inflammation, however, inhaled bronchodilators can prevent exercise-induced asthma.
