Comparison of the efficacy of sublingual immunotherapy and prophylactic treatment with antihistamines on allergic rhinitis symptoms and quality of life in small and large Japanese cedar pollen dispersal years

Key Points

• To compare the efficacy of sublingual immunotherapy (SLIT) and antihistamines in managing allergic rhinitis (AR) symptoms and enhancing quality of life during Japanese cedar pollen dispersal seasons.
• Conducted over different dispersal years of Japanese cedar pollen
• Compared symptom relief with SLIT and prophylactic antihistamine treatment
• Measured quality of life improvements during high pollen periods.
• SLIT demonstrated greater effectiveness in reducing allergic rhinitis symptoms compared to antihistamines during large JC pollen seasons
• Improved quality of life was noted in patients receiving SLIT during these periods.
