Aim of this study is assess the degree of proper inhaler technique and adherence to treatment among adult asthma patients.Methods: Patients using inhalers were identified and interviewed regarding inhaler use. Checklists were used to document the adherence to manufacturers’ directions for each respective inhaler, and data were then tabulated and assessed for the types of inhalers used, incorrectly performed steps in using the inhalers, as well as demographic information of patients.Results: Out of 120 patients that taken as subjects, twenty-four percent of inhalers (29/120) used incorrectly, with the most common errors being improper priming, lack of proper exhalation prior to inhaling the medication, and absence of rinsing mouth following the use of inhaled corticosteroid. Furthermore, only 60% of the patients are adherent to asthma medications.Conclusions: Inhaler technique among adult patients is substandard and is considered a key area for physicians to more proactive in educating patients.
