Preference for Clarinex Tablets vs. Allegra Tablets in Patients With Seasonal Allergies (Study P03177)

Summary

This was a crossover study designed to see if patients with seasonal allergy symptoms preferred Clarinex® or Allegra®. Patients were randomized to take 7 days of Clarinex or Allegra treatment, followed by a 5 to 28-day washout period (days when no drug is given), followed by 7 days of the opposite treatment. At the end of each 7-day treatment, patients were asked questions to determine which drug, Clarinex or Allegra, the patient prefers more.
