Inclusion criteria

* Male and female patients 12 years of age and older with a 2 year history of moderate to severe seasonal allergic rhinitis * Must be in generally good health * Must meet minimum symptom requirements, as specified in the protocol * Must be willing and able to provide informed consent and to participate in all study procedures * Positive skin test to a prevalent fall allergen

Exclusion criteria

* On focused Nasal Examination, the presence of any nasal mucosal erosion, nasal ulceration, or nasal septal perforation at either the screening visit or randomization visit will disqualify the subject from the study. * Other nasal disease(s)likely to affect deposition of intranasal medication, such as sinusitis, rhinitis medicamentosa, clinically significant polyposis, or nasal structural abnormalities. * Nasal Surgery or sinus surgery within the previous year * Chronic sinusitis-more than 3 episodes a year * Planned travel outside of the study area during the study period * The use of any investigational drug within 30 days prior to screening. No investigational products are permitted for use during the conduct of the study. * Presence of any hypersensitivity to drugs similar to azelastine and to either sorbital or sucralose (Splenda brand sweetener) * Women who are pregnant or nursing * Women of childbearing potential who are not abstinent or not practicing medically acceptable method of contraception * Respiratory tract infection within 14 days prior to screening * Respiratory tract infections requiring antibiotic treatment 14 days prior to screening * Asthma (with the exception of mild, intermittent asthma). Subjects with mild, intermittent asthma who only require short-acting inhaled bronchodilators (not for more often tha twice a week) and who do not have nocturnal awakening as a result of asthma are eligible for enrollment * Significant pulmonary disease including COPD * Clinically significant arrythmia or symptomatic cardiac conditions * A known history of alcohol or drug abuse within the last 2 years * Existence of any surgical or medical condition or physical laboratory findings, which in the opinion of the investigator or sponsor's medical monitor, might significantly alter the absorption, distribution, metabolism, or excretion of study drug; that might significantly affect the subject's ability to complete this trial; or their safety in this trial * Clinically relevant abnormal physical findings which, in the opinion of the investigator, would interfere with the objectives of the study or that may preclude compliance with the study procedures.

Each symptom is rated on a scale from 0-3: 0=none, 1=mild, 2=moderate, and 3=severe. Total possible score is 24 per day. Least square means was controlled for study day as the within-patient effect, treatment group and site as the between-patient effects, treatment by-study day interaction, and basline as a covariate.

The RQLQ consists of 7 domains rated on a 7 point scale with 0 being not troubled by the allergy symptoms, and 6 being extremely troubled/all of the time. Total overall score is not calculated by adding all subscales scores for an overall score. Domain score will be calculated from the mean score of all items in the domain. Overall score will be calculated from the mean score of all items.

Mean Change From Baseline in Instantaneous Total Nasal Symptom Score (tNSS) (AM) for the Entire 14-day Study Period Compared to Placebo

End of 24 hour dosing interval: This endpoint is change from baseline in instantaneous tNSS for the 14-day study period compared to placebo to observe if the duration of efficacy lasts 24 hours on a day to day basis. Instantaneous tNSS consists of runny nose, itchy nose, nasal congestion, and sneezing. Each symptom is rated on a scale from 0-3: 0=none, 1=mild, 2=moderate, and 3=severe. Least square means was controlled for study day as the within-patient effect, treatment group and site as the between-patient effects, treatment by-study day interaction, and baseline as a covariate.

Time frame: baseline and 14 days
