Primary Outcome Measures:
  • Mean Change From Baseline in Daytime Nasal Symptoms Score [ Time Frame: Baseline and Week 2 ]
    Mean change from baseline in Daytime Nasal Symptoms score on a 4-point scale [0(best) to 3(worst)]. The average of the 4 individual nasal symptoms scores (Congestion, Rhinorrhea, Itching, and Sneezing) was reported as the Daytime Nasal Symptoms Score.


Secondary Outcome Measures:
  • Mean Change From Baseline in Nighttime Symptoms Score [ Time Frame: Baseline and Week 2 ]
    Mean change from baseline in Nighttime Symptoms Score on a 4-point scale [0(best) to 3(worst)]. The average of 3 scores (Nasal Congestion Upon Awakening, Difficulty Going to Sleep, and Nighttime Awakenings) was reported as the Nighttime Symptoms Score.

  • Mean Change From Baseline in Daytime Eye Symptoms Score [ Time Frame: Baseline and Week 2 ]
    Mean change from baseline in Daytime Eye Symptoms scores on a 4-point scale [0(best) to 3(worst)]. The average of the 4 individual eye symptoms scores (tearing, itchy, red, and puffy eyes) was reported as the Daytime Eye Symptoms Score.

  • Patient's Global Evaluation of Allergic Rhinitis [ Time Frame: Week 2 (or upon discontinuation) ]
    An evaluation by the patient, administered at the last visit (or upon discontinuation) using a 7-point scale, in answer to a single question regarding the change in symptoms as compared to the beginning of the study. Responses were assigned numerical values from 0 (very much better) to 6 (very much worse).

  • Physician's Global Evaluation of Allergic Rhinitis [ Time Frame: Week 2 ]
    An evaluation by the physician, administered at the last visit (or upon discontinuation) using a 7-point scale, of the change in symptoms as compared to the beginning of the study. Responses were assigned numerical values from 0 (very much better) to 6 (very much worse).

  • Mean Change From Baseline in Rhinoconjunctivitis Quality-of-Life Score [ Time Frame: Baseline and Week 2 ]
    Patients completed a validated, self-administered questionnaire, which included 28 questions on a 7-point scale [score 0 (best) to 6 (worst)] across 7 domains: activities, sleep, non-nose/eye symptoms, practical problems, nasal symptoms, eye symptoms, and emotional. The scores for each domain were averaged, then the scores for the 7 domains were averaged for the overall score.
