Objectives: To assess the impact on patient adherence to intranasal corticosteroid spray by using medication adherence chart and development of potential strategies to reduce non-compliance. Methodology: This prospective cohort study was carried out on 102 outpatients in a tertiary care hospital, Kerala state for one year in the age group of 12 and above, these patients were categorised as case and control where case group were provided with administration chart and counselling. On the review date, we monitored the administration chart and reviewed the patient quality of life and all participants were asked to fill the questionnaire regarding the factors that may have influenced their adherence to treatment. Each factor that may have affected adherence to the prescribed medication is evaluated according to the MARS score and all variables were assessed. Results: Among 102 patients, the reasons for nonadherence were measured, among that forgetfulness, due to cost of spray, fear of persistent use of medication for lifelong were most predominant factor. According to MARS score, there were statistically significant association exist between medication adherence before and after intervention (p <0.001). Conclusion: Patient’s usage and adherence with intranasal corticosteroids are sparse in the treatment of allergic rhinitis. Therefore, based on our results, patients must be given proper education and to help patients overcome these barriers by interventional aids which can promote the proper use of intranasal corticosteroids and prevent remission.
