Materials and Methods: A prospective observational study was conducted collaboratively by theDepartments of ENT and Pharmacology among 75 patients with allergic rhinitis. Demographic and clinical characteristics,prescribed medications, adherence status, reasons for non-adherence, and symptom severity were recorded. Clinical responsewas assessed using changes in Total Nasal Symptom Score (TNSS). Appropriate descriptive and inferential statistical testswere applied, with p<0.05 considered significant.
