Nasal symptom scores after allergen challenge with and without pretreatment with fexofenadine. Subjects received either placebo or fexofenadine for 7 days at the end of which period they underwent a nasal allergen challenge with ragweed or timothy. Symptoms were scored for 6 hours after the challenge as described. After a 1-week washout period, subjects were crossed over to the other medication and a second identical challenge was performed at the end of another 7 days of medication.
