In children 6 months to 5 years of age, the recommended dose is 1.25 mg once daily in the evening. A retrospective population pharmacokinetic analysis was conducted in 323 subjects (181 children 1 to 5 years of age, 18 children 6 to 11 years of age, and 124 adults 18 to 55 years of age) who received single or multiple doses of levocetirizine ranging from 1.25 mg to 30 mg. Data generated from this analysis indicated that administration of 1.25 mg once daily to children 6 months to 5 years of age results in plasma concentrations similar to those of adults receiving 5 mg once daily. Medscape - Allergic rhinitis, urticaria dosing for Xyzal (levocetirizine), frequency-based adverse effects, comprehensive interactions, contraindications, pregnancy & lactation schedules, and cost information.

Efficacy was assessed using a total symptom score from patient recording of 4 symptoms (sneezing, rhinorrhea, nasal pruritus, and ocular pruritus) in three studies and 5 symptoms (sneezing, rhinorrhea, nasal pruritus, ocular pruritus, and nasal congestion) in one study. Xyzal tablets are white, film-coated, oval-shaped, scored, imprinted (with the letter Y in red color on both halves of the scored tablet) and contain 5 mg levocetirizine dihydrochloride. Xyzal 5 mg demonstrated a greater decrease from baseline in the reflective pruritus severity score than placebo and the difference from placebo was statistically significant. The primary endpoint was the mean total symptom score averaged over the first week and over 4 weeks for perennial allergic rhinitis trials. This drug is used to treat symptoms of year-round allergies and hives in adults and children who are at least 6 months old. Dose Adjustment for Renal and Hepatic Impairment.

There are no long term clinical trials in children below 12 years of age with allergic rhinitis or chronic idiopathic urticaria. In this trial, each of the three doses of Xyzal demonstrated greater decrease in the reflective pruritus severity score than placebo and the difference was statistically significant for all three doses (see Table 6). Levocetirizine was not mutagenic in the Ames test, and not clastogenic in the human lymphocyte assay, the mouse lymphoma assay, and in vivo micronucleus test in mice. Additional efficacy variables were the instantaneous pruritus severity score, the number and size of wheals, and duration of pruritus. It's used to treat seasonal allergies in adults and children who are at least 2 years old.

The recommended dose of XYZAL in patients 6 months to 2 years of age for the treatment of the symptoms of perennial allergic rhinitis and 6 months to 11 years of age with chronic idiopathic urticaria is based on cross-study comparisons of the systemic exposure of XYZAL in adults and pediatric patients and on the safety profile of XYZAL in both adult and pediatric patients at doses equal to or higher than the recommended dose for patients 6 months to 11 years of age. The elevations were transient and did not lead to discontinuation in any patient. Cetirizine lowered pup body weight gain during lactation at an oral dose in dams that was approximately 95 times the MRHD (on a mg/m2 basis with a maternal oral dose of 96 mg/kg/day); however, there were no effects on pup weight gain at an oral dose in dams that was approximately 25 times the MRHD (on a mg/m2 basis with a maternal oral dose of 24 mg/kg/day). XYZAL is available as 2.5 mg/5 mL (0.5 mg/mL) oral solution and as 5 mg breakable (scored) tablets, allowing for the administration of 2.5 mg, if needed.
