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.
