<p>Allergic rhinitis (AR) is a very common but often overlooked condition worldwide. Although there are well-established guidelines, the diagnosis and management of AR are often suboptimal due to insufficient recognition of its prevalence, disease burden, and impact on quality of life and work productivity. This study aims to determine the prevalence of AR, the burden of its symptoms and its impact on quality of life using three validated questionnaires, including the Score for Allergic Rhinitis (SFAR), the Mini rhinoconjunctivitis questionnaire (MiniRQLQ) and the Work Productivity and Activity Impairment (WPAI) questionnaire sequentially. This is a questionnaire-based descriptive cross-sectional study conducted from November 2022 to February 2024. All the undergraduate medical students from our institution in Puducherry who have consented to participate were included in the study. Of the 614 participants,116 had an SFAR score ≥ 7, giving an estimated prevalence of allergic rhinitis to be 18.89%. Among the various AR symptoms, nasal and eye symptoms cause moderate trouble in most participants and cause moderate impairment in performing regular activities. The impairment caused by allergic rhinitis led to 11.7% absenteeism, 30.6% presenteeism, 33.9% work impairment, and 41.5% overall activity impairment. There is a notable burden of AR among medical students despite their knowledge of the subject and immediate access to healthcare. This underscores the need for better health education and a deeper understanding of the disease to enhance management and overall well-being for both patients and practitioners.</p>
