About this study
Official title: Preference Evaluation of Clarinex Tablets vs. Zyrtec Tablets in Subjects With Symptomatic Allergic Rhinitis
This was a crossover study designed to see if patients with allergy symptoms preferred Clarinex® or Zyrtec®. Patients were randomized to take 7 days of Clarinex or Zyrtec 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 Zyrtec, the patient prefers more.
- Being tested
- Desloratadine 5 mg (Clarinex), Cetirizine (Zyrtec)
- Medical subject headings

Measured: 1 day after the last treatment period (Visit 5)
Secondary outcomes (1)
Subject Non-Comparative Evaluation and subject Response to Therapy
Measured: 1 day after the end of each 7-day treatment period (Visit 3 and Visit 5)
