Comparison of Xylitol and Normal Saline Nasal Irrigation for the Treatment of Allergic Rhinitis.

INTERVENTION: Intervention1: Xylitol Nasal Irrigation: Participants will perform nasal irrigation at home using a 5 percent xylitol solution prepared by dissolving 2 packets of 10 g xylitol powder in 400 ml of sterile water. The solution will be administered by the intranasal route using a nasal irrigation squeeze bottle. Each irrigation session will consist of 400 ml of the prepared solution, with 200 ml delivered into each nasal cavity. The irrigation will be performed once daily for a total duration of 6 weeks. Participants will be instructed regarding the preparation of the solution and the standardized nasal irrigation technique before starting the intervention. Participants will continue to receive standard medical treatment for allergic rhinitis throughout the study period Control Intervention1: Normal Saline Nasal Irrigation: Participants will perform nasal irrigation at home using a 0.9 percent normal saline solution prepared by dissolving 2 packets of 1.8 g salt powder in 400 ml of sterile water. The solution will be administered by the intranasal route using a nasal irrigation squeeze bottle. Each irrigation session will consist of 400 ml of the prepared solution, with 200 ml delivered into each nasal cavity. The irrigation will be performed once daily for a total duration of 6 weeks. Participants will be instructed regarding the preparation of the solution and the standardized nasal irrigation technique before starting the intervention. Participants will continue to receive standard medical treatment for allergic rhinitis throughout the study period.
