A systematic review for improper application of nasal spray in allergic rhinitis: A proposed role of community pharmacist for patient education and counseling in practical setting.

The application of nasal spray is encountered with technique errors, which can lead to decreased therapeutic response and treatment failure. Community pharmacists can play a pivotal role in providing appropriate knowledge and counseling services for the proper and effective use of these topical drugs. The aim of this systematic review was to assess the most important aspects of application technique errors and the impact of community pharmacist-led interventions on the provision of patient education and counseling regarding the application of these topical preparations in clinical practice. Preferred reporting items for systematic review and meta-analysis (PRISMA) criteria were used to set up a systematic search through different databases, including Scopus, Web of Science, and PubMed. A total of 10 articles were included in this study. Nearly three-quarters of the publications discussed improper technique, poor knowledge about installation technique, and poor adherence. Only 2 studies discussed pharmacist intervention, which comprised individualized brief education and training on the correct use of the nasal spray. The study highlights that there are many different aspects of application errors encountered by patients while using nasal spray. The study also highlights that there is a dearth of involvement of community pharmacists and pharmacist-led interventions for proper technique and application of these topical preparations.
