Inclusion criteria

• Male or non-pregnant, non-lactating female 12 years or age or older.
• Signed informed consent form, which meets all criteria of current FDA regulations. For patients under the age of majority in the state the study is being conducted (18 years in most states) the parent or legal guardian should sign the consent form and the child will be required to sign a patient "assent" form that will be written in such a way as to be understandable to a child.

In order for hormonal birth control to be considered a reliable method the patient must have been on their regimen for at least 28 days.
• Documented positive allergic skin test, performed within the previous 12 months, to one or more of the allergens in season at the time the study is being conducted.
• A minimum of two years of previous history of seasonal allergic rhinitis to the pollen/allergen in season at the time the study is being conducted.
• A score of at least 6 on the reflective Total Nasal Symptom Score (rTNSS) and a minimum score of at least 2 for "nasal congestion" and a minimum score of at least 2 for one of the remaining 3 symptoms. The patient must meet these minimum requirements prior to being entered into the placebo lead-in period and also prior to being enrolled in the randomized, active treatment period of the study.

Exclusion criteria

• Under 12 years of age.
• Females who are pregnant, lactating, or likely to become pregnant during the study.
• Negative or lack of documented skin allergen test (performed within the previous 12 months) to at least one of the allergens in season at the time the study is being conducted. The results of all positive skin allergen test results should be reported.
• Patients who suffer from chronic signs and symptoms of perennial allergic rhinitis (PAR) should be excluded from the study unless the Investigator assesses that the patient's current signs and symptoms are a clear exacerbation of Seasonal Allergic Rhinitis (SAR) rather than chronic PAR.
• Patients who suffer only from perennial allergic rhinitis of seasonal allergic rhinitis to a different allergen than that in season at the time the study in conducted.
• Previous history of less that 2 years of seasonal allergic rhinitis to the pollen/allergen in season at the time the study is being conducted.
• A total score of less than 6 on the reflective Total Nasal Symptom Score (rTNSS) or a score less than 2 for "nasal congestion" or a score less than 2 for all 3 remaining symptoms. Any patient who meets the minimum rTNSS requirements at the start of the placebo lead-in period but no longer meets the requirements prior to the randomized active treatment period of the study cannot continue in the active treatment period.
• History of asthma over the previous two years that required chronic therapy. Occasional acute or mild exercise induced asthma will be allowable on the condition that the treatment of the attacks is restricted to beta-agonists only.
• Patients with nasal conditions, including infectious rhinitis, rhinitis medicamentosa, or atrophic rhinitis.
• Clinically significant nasal deformity (e.g. significantly deformed septum, nasal polyps or ulcers) or any recent nasal surgery or trauma that has not completely healed.
• Sinus infection within the previous 30 days or history of re-occurring sinus infections.
• Patient has started immunotherapy (including topical or desensitization therapy) or changed their dose of immunotherapy within 30 days of the first placebo lead-in dose, or is likely to have to start immunotherapy or change their current dose during the study.
• Treatment for oral Candidiasis within 30 days of starting the study or a current oral Candidiasis infection.
• Upper respiratory tract infection within the previous 30 days.
• Patients with a history of tuberculosis.
• Patients with the presence of glaucoma, cataracts, ocular herpes simplex, conjunctivitis, or other eye infection not related to the diagnosis of SAR within 14 days of enrollment.
• The patient has had recent exposure (30 days) or was at risk of being exposed to chicken pox or measles.
• Patients with any untreated fungal, bacterial, or systemic viral infections within the previous 30 days.
• Use of any ophthalmic steroids within 14 days or nasal, inhaled, or systemic steroids within 30 days of the study start. Super or high potency topical steroids should not be used during the study. The use of low potency topical corticosteroids will be allowed. The use of hormonal contraceptives or hormone replacement therapy is allowed, on the condition that the patient has been on a stable dosing regime for at least 28 days prior to the start of the study and remains on the same dosing regimen during the study.
• Use of intranasal or systemic second-generation anti-histamines within 10 days of enrollment.
• Use of intranasal cromolyn within 14 days of enrollment.
• Use of intranasal or systemic first-generation anti-histamines, leukotriene receptor antagonists or other nasal decongestants within 3 days of enrollment.
• Use of any tricyclic anti-depressant within 30 days of enrollment.
• Patients with attention-deficit disorder being treated with methylphenidate containing products that have not been on a stable dosing regimen for at least 30 previous days and who cannot remain on the same dosing regime throughout the study.
• Desensitization therapy to the seasonal allergen that is causing the patient's allergic rhinitis within the previous 6 months.
• Previous SAR and/or PAR that has proven unresponsive to steroid therapy.
• Any known hypersensitivity to mometasone, other steroids, or any of the components of the study nasal spray.
• Significant history of current evidence of chronic infectious disease, system disorder, organ disorder, or other medical condition that in the Investigator's opinion would place the study patient at undue risk by participating or could jeopardize the integrity of the study evaluations.
