Primary Outcome Measures:
  • Number of Subjects Who Preferred Desloratadine RediTab or Zyrtec Chewable Tablet. [ Time Frame: Following the second dose (8-10 minutes after the first dose) ]
    A product preference questionnaire was completed after the administration of the second study drug. An interviewer instructed the subject "now that you have tasted the two tablets, show us which tablet you like more" and the subject then marked which tablet he/she preferred. If the subject had no preference, the response was recorded accordingly.
