Inclusion Criteria:

  • Subjects must demonstrate their willingness to participate in the study and comply with its procedures by signing a written informed consent.
  • Subjects must be >= 18 years of age, of either sex and any race.
  • Women of childbearing potential (includes women who are less than 1 year postmenopausal and women who become sexually active) must be using an acceptable method of birth control (e.g., hormonal contraceptive, medically prescribed IUD, condom in combination with spermicide) or be surgically sterilized (e.g., hysterectomy or tubal ligation). Women of childbearing potential should be counseled in the appropriate use of birth control while in this study. Women who are not currently sexually active must agree and consent to use one of the above-mentioned methods should they become sexually active while participating in the study.
  • Subjects must be in general good health; i.e., they must be free of any clinically significant disease (other than CIU) that would interfere with study evaluations.
  • Subjects must understand and be able to adhere to the dosing and visit schedules, and agree to complete the questionnaires and to record symptom severity scores, medication times, concomitant medications, and adverse events accurately and consistently in a daily diary.
  • Subjects must have at least a 6-week history of CIU (pruritus and hives) prior to Visit 1 (Screening).
  • Subjects must have a pruritus score >= 2 and a hive score >= 1 at Visit 1.
  • Subjects must be experiencing a current CIU flare of at least 3 weeks duration, with hives present at least 3 days per week, prior to Visit 1 (Screening).
  • Subjects must score the overall condition of CIU >= 2 at both Visit 1 (Screening) and Visit 2 (Baseline).
  • Subjects must have a total pruritus score of >= 14 for the sum of morning and evening (reflective) diary scores for the 3 days prior to Visit 2 (Baseline) plus the morning score on the day of Visit 2.
  • Women of childbearing potential must have a negative urine pregnancy test at Visit 2 (Baseline).

Exclusion Criteria:

  • Women who are pregnant or nursing.
  • Subjects who have not observed the designated washout periods for any of the prohibited medications outlined.
  • Subjects with asthma requiring chronic use of inhaled or systemic corticosteroids.
  • Subjects with drug or food allergies that manifest as skin reactions.
  • Subjects with urticaria that is primarily due to physical urticaria or other known etiology.
  • Subjects with CIU unresponsive to antihistamines.
  • Subjects who have been hospitalized (including an emergency department visit) because of deterioration in their CIU within 3 months prior to Visit 1 (Screening).
  • Subjects with a history of hypersensitivity to desloratadine or any of its excipients.
  • Subjects previously randomized into this study.
  • Subjects who are staff personnel directly involved with the administration of this study.
  • Subjects who have any clinically significant metabolic, cardiovascular, immunologic, neurologic, hematologic, gastrointestinal, cerebrovascular, or respiratory disease, or any other disorder which, in the judgment of the Investigator, may interfere with the study evaluations or affect subject safety.
  • Subjects with a history of psychosis, antagonistic personality, poor motivation, hypochondriasis, or any other emotional or intellectual problems that are likely to limit the validity of consent to participate in the study.
  • Subjects with a history of noncompliance with medications or treatment protocols.
