Purpose of review The long-term goals of asthma management are to control symptoms and to reduce the risk of exacerbations. Inhaled medication is the cornerstone of pharmacological treatment for asthma; therefore, good inhalation technique is the key for asthma management. However, up to 70% of asthma patients do not use their inhalers correctly. There is evidence on how poor inhalation technique is associated to poor asthma control. The purpose of this review is to present the most recent research in this field to help clinicians understand the importance of proper inhalers use and the possible interventions to optimize patients’ inhalation technique.

Recent findings New evidence on how poor inhaler technique and specific critical errors are significantly associated to poor asthma control and exacerbations and how this negative impact could be improved by optimizing device selection, enhancing shared decision-making and giving more importance to education, both for patients and healthcare professionals. New devices and additional tools might help patients to achieve the correct inhaler technique and could form the basis of simplified educational interventions.

Summary There is an urgent need for specific interventions including new educational strategies to minimize the negative effects of wrong inhalation technique in asthma clinical outcomes.
