Outcome Measures
Primary Outcomes (2)
Modified Epworth Sleepiness Scale
Epworth Sleepiness Scale ratings (0 to 24); higher scores = increased sedation. This was measured over the 36 days of the study (at the end of each washout period and each intervention period); measured on days 5, 12, 17, 24, 29, and 36. This was mean data for all interventions.
36 days of the study
Likert Score Rating Global Sedation
Likert score range 1 to 9 (no sedation to extreme sedation). Highers scores indicate increased sedation. This was measured on days days 5, 12, 17, 24, 29, and 36 of the study. This was mean data for all interventions.
duration of study (36 days)
Secondary Outcomes (1)
Total Four Symptom Scores (Allergy Symptoms)
same as primary outcome measure (obtain on days 5, 12, 17, 24, 29, and 36)
Study Arms (3)
Levocetirzine
ACTIVE COMPARATOR5 mg daily x 7 days (note = cross over = all participants receive active comparators and placebo)
cetirizine
ACTIVE COMPARATOR10 mg daily x 7 days. Note = crossover study, so all participants recieve all active comparators and placebo.
placebo
PLACEBO COMPARATORone tablet daily x 7 days; note that this is a crossover study so all participants receive all active comparators and placebo

Eligibility Criteria
You may qualify if:
- patients 18 years of age or older
- patients with perennial allergic rhinitis sensitized (positive RAST within the last 3 years or wheal greater than or equal to 3 mm within the last 3 years) to either:
- dust mite
- cat (if they own an indoor cat)
- dog (if they own an indoor dog)
- will allow for sensitization to tree, grass, or weed pollen, cockroach, or mold
- history of reported sedation/somnolence when taking cetirizine
- patient must have taken cetirizine for at least 1 week prior to discontinuing it
- patients must have either tolerated levocetirizine in the past or have never tried levocetirizine.
You may not qualify if:
- chronic urticaria requiring ongoing antihistamine or steroid treatment
- atopic dermatitis requiring ongoing antihistamine or steroid treatment
- URI or sinus infection during the 2 weeks preceding the beginning of the study
- vasomotor (non-allergic) or irritant rhinitis
- afrin use
- elderly or over 77 years of age (could affect creatinine clearance) or chronic renal insufficiency
- patients who have not tolerated levocetirizine in the past due to sedation.
- taking other prescription or over the counter antihistamines and unwilling to stop them during the study
- the presence of a sleep disorder such as sleep apnea or narcolepsy
- the use of as needed sleeping aid medication
- the presence of other chronic medical conditions which in the opinion of the investigator would prevent the subject from being able to participate effectively
