Brief Summary

Allen Kaplan is a prominent American allergist with the reputation of leader in the field of chronic urticaria. He advocates treatment with first generation hydroxyzine, which he considers at least as effective as modern second generation H1-blockers in suppressing the symptoms of difficult-to-treat / systemic-steroid-dependant cases of chronic urticaria. He further speculates that hydroxyzine may have the advantage to better suppress itch and improve nighttime sleep. This has prompted many practitioners around the world to believe that adding hydroxyzine to the treatment regimen at bed time at night may be beneficial to patients. At the same time European guidelines indicate modern second generation H1-blockers in higher than conventional doses as drugs of choice for such cases. However, there is no evidence from clinical trials addressing this controversy. The investigators' previous studies suggest that levocetirizine at quadruple doses may be beneficial in difficult to treat urticaria by reducing lesions and itch, improving quality of life and night time sleep, while not causing day time somnolence. First generation H1-receptor antagonists and hydroxyzine among them are known to penetrate the blood / brain barrier and to cause sedation. The question stays whether this sedation is beneficial to the subjects with chronic urticaria at night, whether it has any hang-over unwanted effects the following day and whether this has any influence on the overall urticaria-specific quality of life.

Outcome Measures

Primary Outcomes (1)

  • Urticaria specific quality of life

    The primary objective of the study is to compare the effect on urticaria specific quality of life of two regimens: levocetirizine 20 mg per day (4x1 tablets) vs. levocetirizine 15 mg (3x1 tablets) + hydroxyzine 50 mg (2 tablets) before night time sleep.

    1 year

Secondary Outcomes (5)

  • Effect of the two regimens on urticaria symptoms

    1 year

  • Effect on night time sleep

    1 year

  • Effect on day time somnolence

    1 year

  • The effect on blood eosinophil numbers, Na+, K+, ALAT, ASAT, ECG
