Asthma is a chronic respiratory condition affecting over 300 million individuals worldwide, with medication nonadherence being a significant barrier to effective management. Despite advancements in medical therapies, adherence rates remain suboptimal, ranging between 20 and 80%, exacerbating asthma morbidity and mortality. Wearable technologies, including smart inhalers, wrist-based trackers, and biosensors, have emerged as innovative tools to monitor and enhance medication adherence in asthma care. This narrative review aims to critically evaluate the role of devices in improving adherence and optimizing asthma management. A comprehensive search was conducted across PubMed, Scopus, and Cochrane databases using predefined keywords, yielding 11 studies, 4 of which met the inclusion criteria. The review synthesizes evidence on wearable technologies’ accuracy, reliability, and potential limitations, highlighting their ability to provide real-time monitoring, personalized feedback, and predictive modeling through advanced sensors and artificial intelligence. Despite their promise, barriers such as high costs, technological usability, and patient-centric factors hinder widespread adoption. Integration with telemedicine platforms and further validation through longitudinal studies are essential to maximize their impact. Wearable technologies hold significant potential to transform asthma management by improving medication adherence, reducing healthcare costs, and enhancing patient outcomes. Addressing identified challenges will be crucial to their success in clinical practice.
