• Subject has uncontrolled Hypothyroidism.

• Patient is enrolled in an investigational drug or device study or has participated in such a study within the last 30 days prior to screening that in the opinion of the Investigator would interfere with the study results.
• Patient presents with any condition or situation which, in the Investigator's opinion, puts the Subject at risk, could confound the study results, or may interfere significantly with the Subject's participation in the study.
• Subject presents with acute sinusitis at time of treatment or other sino-nasal related illness other than rhinitis.
