Inclusion Criteria:

1. Male or female between the ages of 2 and 5 years, inclusive
2. General good health, and free of any concomitant conditions or treatment that could interfere with study conduct, influence the interpretation of study observations/results, or put the patient at increased risk during the trial
3. A demonstrated sensitivity to at least one allergen known to induce PAR through a standard prick skin test within one year of study start. A positive test is defined as a wheal diameter at least 3mm larger than the control wheal for th eprick test
4. Parent or legal guardian is capable of understanding the requirements, risks, and benefits of study participation, and, as judged by the investigator, capable of giving informed consent and comply with all study requirements (visits, record-keeping, etc.)
5. A history of PAR for a minimum of 3 months preceding the study screening visit (B0). The PAR must have been of sufficient severity to require treatment (either continuous or intermittent) in the past and in the investigators judgment is expected to continue to require treatment for the study duration.

Exclusion Criteria:

1. History of physical findings of nasal pathology, including nasal polyps (within the last 60 days) or other clinically significant respiratory tract malformations, recent nasal biopsy (within the last 60 days), nasal trauma, or surgery and atrophic rhinitis or rhinitis medicamentosa (within the last 60 days).
2. Participation in any investigational drug trial within the 30 days preceding the Screening Visit (B0) or at any time during the trial
3. A known hypersensitivity to any corticosteroid or any of the excipients in the formulation.
4. History of a respiratory infection or disorder [including, but not limited to bronchitis, pneumonia, the common cold, acute or chronic sinusitis, flu, severe acute respiratory syndrome (SARS)] within the 14 days preceding the Screening Visit, or development of a respiratory infection during the Screening Visit (B0)
5. History of a positive test for HIV, hepatitis B or hepatitis C.
6. Active asthma requiring treatment with inhaled or systemic corticosteroids and/or routine use of b-agonists and any controller drugs (e.g. theophylline, leukotrienes, etc.) intermittent use of b-agonists is acceptable
7. Use of any prohibited concomitant medications within the prescribed (per protocol) withdrawal periods prior to the screening visit (B0) and during the entire screening period and treatment duration
8. Use of antibiotic therapy for acute conditions within 14 days prior to the Screening Visit (B0).
9. Initiation of immunotherapy during the study period or dose escalation during the study period. However, initiation of immunotherapy 90 days or more prior to the Screening Visit AND use of a stable (maintenance) dose (30 days or more) may be considered for inclusion.
10. Non-vaccinated exposure to, or infection with, chickenpox or measles within the 21 days preceding the Screening Visit (B0).
11. Exposure to systemic corticosteroids for any indication, chronic or intermittent (e.g.: contact dermatitis), during the past 2 months, or presence of an underlying condition that can reasonably be expected to require treatment with corticosteroids during the course of the study.
12. Use of topical corticosteroids in concentrations in excess of 1% hydrocortisone for dermatological conditions during the past 1 month, or presence of an underlying condition that can reasonably be expected to require treatment with such preparations during the course of the study.
13. Intraocular pressure at the screening visit (B0) of 21 mm Hg or greater or failed reading at the screening Visit (B0)
14. Glaucoma requiring treatment
15. Use of antiepileptic drugs for epilepsy within 30 days of the screening visit (B0) or anytime during the treatment period.
16. Initiation of pimecrolimus 1% cream or tacrolimus ointment 0.1% or 0.03% during the study period or planned dose escalation during the study period. However, initiation of these creams/ointments 30 days or more prior to the screening Visit (B0) AND use of a stable (maintenance) dose during the study period may be considered for inclusion
