Treatment of Olfactory Dysfunction in Seasonal Allergic Rhinitis
People with allergies frequently complain of a loss or reduction in the sense of smell.

 Exclusion Criteria:

 1. Women of childbearing potential not using the contraception method(s) (Birth control
 pills, depo Provera, double barrier) as well as women who are breastfeeding.

 2. Patients with severe medical condition(s) that in the view of the investigator
 prohibits participation in the study (heart, lung, kidney, neurological, oncologic or
 liver disease).

 3. Use of any other investigational agent in the last 30 days.

 4. Absence of olfactory or nasal symptoms.

 5. Use of medications that may affect olfaction.

 6. Medical conditions that may affect olfaction.
