<p><b>OBJECTIVE</b>To evaluate the effects of nasal mometasone furoate on moderate to severe allergic rhinitis.</p><p><b>METHODS</b>Patients with moderate to severe allergic rhinitis were enrolled and received mometasone furoate nasal spray 200 microg once daily for four weeks. Four hundreds and sixty-three patients completed the study. We weekly interviewed the patients to evaluate the symptoms, and the affection of disease on night sleep and daily life. Mini Rhinoconjunctivitis Quality of Life Questionnaire (Mini-RQLQ) and Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ) were used to evaluate the quality of life.</p><p><b>RESULTS</b>The individual and total symptomatic scores of week 1, week 2 and week 4 decreased compared with baseline. The scores of Mini-RQLQ and NRQLQ of week 1, week 2 and week 4 decreased compared with baseline too. The scores of the next visit were significantly lower than those of the previous visit (P < 0.01).</p><p><b>CONCLUSIONS</b>A four-week administration of mometasone furoate nasal spray can effectively treat allergic rhinitis.</p>
