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. XYZAL can be taken without regard to food consumption. Perennial Allergic Rhinitis ( 2.1 ) Children 6 months to 2 years of age: 1.25 mg (1/2 teaspoon oral solution) (2.5 mL) once daily in the evening Chronic Idiopathic Urticaria ( 2.2 ) Adults and children 12 years of age and older: 5 mg once daily in the evening Children 6 to 11 years of age: 2.5 mg once daily in the evening Children 6 months to 5 years of age: 1.25 mg (1/2 teaspoon oral solution) (2.5 mL) once daily in the evening Renal Impairment Adjust the dose in patients 12 years of age and older with decreased renal function ( 12.3 ) 2.1 Perennial Allergic Rhinitis Children 6 months to 2 Years of Age The recommended initial dose of XYZAL is 1.25 mg (1/2 teaspoon oral solution) (2.5 mL) once daily in the evening. The 1.25 mg once daily dose should not be exceeded based on comparable exposure to adults receiving 5 mg [see Clinical Pharmacology ( 12.3 )] . 2.2 Chronic Idiopathic Urticaria Adults and Children 12 Years of Age and Older The recommended dose of XYZAL is 5 mg (1 tablet or 2 teaspoons [10 mL] oral solution) once daily in the evening. Some patients may be adequately controlled by 2.5 mg (1/2 tablet or 1 teaspoon [5 mL] oral solution) once daily in the evening.…

The following clinically significant adverse reactions are described elsewhere in the labeling: Somnolence [see Warnings and Precautions ( 5.1 )] Urinary Retention [see Warnings and Precautions ( 5.2 )] Risk of New Onset Pruritus After Discontinuation of XYZAL [see Warnings and Precautions ( 5.3 )] The most common adverse reactions (rate ≥2% and > placebo) were somnolence, nasopharyngitis, fatigue, dry mouth, and pharyngitis in subjects 12 years of age and older, and pyrexia, somnolence, cough, and epistaxis in children 6 to 12 years of age. In subjects 1 to 5 years of age, the most common adverse reactions (rate ≥2% and > placebo) were pyrexia, diarrhea, vomiting, and otitis media. In subjects 6 to 11 months of age, the most common adverse reactions (rate ≥3% and > placebo) were diarrhea and constipation. ( 6.1 ).

The safety data described below reflect exposure to XYZAL in 2708 patients with allergic rhinitis or chronic idiopathic urticaria in 14…

The use of XYZAL is contraindicated in: Patients with a known hypersensitivity to levocetirizine or any of the ingredients of XYZAL or to cetirizine ( 4.1 ) Patients with end-stage renal disease at less than 10 mL/min creatinine clearance or patients undergoing hemodialysis ( 4.2 ) Children 6 months to 11 years of age with renal impairment ( 4.3 ) 4.1 Patients with Known Hypersensitivity Patients with known hypersensitivity to levocetirizine or any of the ingredients of XYZAL, or to cetirizine. Observed reactions range from urticaria to anaphylaxis [see Adverse Reactions ( 6.2 ) ] . 4.2 Patients with End-Stage Renal Disease Patients with end-stage renal disease (CL CR <10 mL/min) and patients undergoing hemodialysis 4.3 Pediatric Patients with Impaired Renal Function Children 6 months to 11 years of age with impaired renal function

Overdosage has been reported with XYZAL. Symptoms of overdose may include drowsiness in adults. In children agitation and restlessness may initially occur, followed by drowsiness. There is no known specific antidote to XYZAL. Should overdose occur, symptomatic or supportive treatment is recommended. XYZAL is not effectively removed by dialysis, and dialysis will be ineffective unless a dialyzable agent has been concomitantly ingested. The acute maximal non-lethal oral dose of levocetirizine was 240 mg/kg in mice (approximately 190 times the maximum recommended daily oral dose in adults, approximately 230 times the maximum recommended daily oral dose in children 6 to 11 years of age, and approximately 180 times the maximum recommended daily oral dose in children 6 months to 5 years of age on a mg/m 2 basis). In rats the maximal non-lethal oral dose was 240 mg/kg (approximately 390 times the maximum recommended daily oral dose in adults, approximately 460 times the maximum recommended daily oral dose in children 6 to 11 years of age, and approximately 370 times the maximum recommended daily oral dose in children 6 months to 5 years of age on a mg/m 2 basis).

In vitro data indicate that levocetirizine is unlikely to produce pharmacokinetic interactions through inhibition or induction of liver drug-metabolizing enzymes. No in vivo drug-drug interaction studies have been performed with levocetirizine. Drug interaction studies have been performed with racemic cetirizine. 7.1 Antipyrine, Azithromycin, Cimetidine, Erythromycin, Ketoconazole, Theophylline, and Pseudoephedrine Pharmacokinetic interaction studies performed with racemic cetirizine demonstrated that cetirizine did not interact with antipyrine, pseudoephedrine, erythromycin, azithromycin, ketoconazole, and cimetidine. There was a small decrease (~16%) in the clearance of cetirizine caused by a 400 mg dose of theophylline. It is possible that higher theophylline doses could have a greater effect. 7.2 Ritonavir Ritonavir increased the plasma AUC of cetirizine by about 42% accompanied by an increase in half-life (53%) and a decrease in clearance (29%) of cetirizine. The disposition of ritonavir was not altered by concomitant cetirizine administration.
