levocetirizine dihydrochloride - Use TABLET

Indications for LEVOCETIRIZINE DIHYDROCHLORIDE (tablet) refers to the medical reasons for why levocetirizine dihydrochloride is used and recommended as a treatment. Contraindications for levocetirizine dihydrochloride refers to medical situations for which levocetirizine dihydrochloride is not recommended due to side effects or other risks.

Contraindications

The use of levocetirizine dihydrochloride is contraindicated in:

patients with known hypersensitivity

Patients with known hypersensitivity to levocetirizine or any of the ingredients of levocetirizine dihydrochloride, or to cetirizine. Observed reactions range from urticaria to anaphylaxis [see Adverse Reactions (6.2)].

patients with end-stage renal disease

Patients with end-stage renal disease (CLCR < 10 mL/min) and patients undergoing hemodialysis

pediatric patients with impaired renal function

Children 6 months to 11 years of age with impaired renal function

Use In Specific Populations

pregnancy

pregnancy category b

There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, levocetirizine dihydrochloride should be used during pregnancy only if clearly needed.

teratorgenic effects:

In rats and rabbits, levocetirizine was not teratogenic at oral doses approximately 320 and 390, respectively, times the maximum recommended daily oral dose in adults on a mg/m2 basis.

nursing mothers

No peri- and post-natal animal studies have been conducted with levocetirizine. In mice, cetirizine caused retarded pup weight gain during lactation at an oral dose in dams that was approximately 40 times the maximum recommended daily oral dose in adults on a mg/m2 basis. Studies in beagle dogs indicated that approximately 3% of the dose of cetirizine was excreted in milk. Cetirizine has been reported to be excreted in human breast milk. Because levocetirizine is also expected to be excreted in human milk, use of levocetirizine dihydrochloride in nursing mothers is not recommended.

pediatric use

The recommended dose of levocetirizine dihydrochloride for the treatment of the uncomplicated skin manifestations of chronic idiopathic urticaria in patients 6 months to 17 years of age is based on extrapolation of efficacy from adults 18 years of age and older [see Clinical Studies (14)].

The recommended dose of levocetirizine dihydrochloride in patients 6 months to 11 years of age for the treatment of the symptoms of perennial allergic rhinitis and chronic idiopathic urticaria and in patients 2 to 11 years of age for the treatment of symptoms of seasonal allergic rhinitis is based on cross-study comparisons of the systemic exposure of levocetirizine dihydrochloride in adults and pediatric patients and on the safety profile of levocetirizine dihydrochloride 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 safety of levocetirizine dihydrochloride 5 mg once daily was evaluated in 243 pediatric patients 6 to 12 years of age in two placebo-controlled clinical trials lasting 4 and 6 weeks. The safety of levocetirizine dihydrochloride 1.25 mg twice daily was evaluated in one 2-week clinical trial in 114 pediatric patients 1 to 5 years of age and the safety of levocetirizine dihydrochloride 1.25 mg once daily was evaluated in one 2-week clinical trial in 45 pediatric patients 6 to 11 months of age [see Adverse Reactions (6.1)].

The effectiveness of levocetirizine dihydrochloride 1.25 mg once daily (6 months to 5 years of age) and 2.5 mg once daily (6 to 11 years of age) for the treatment of the symptoms of seasonal and perennial allergic rhinitis and chronic idiopathic urticaria is supported by the extrapolation of demonstrated efficacy of levocetirizine dihydrochloride 5 mg once daily in patients 12 years of age and older based on the pharmacokinetic comparison between adults and children.

Cross-study comparisons indicate that administration of a 5 mg dose of levocetirizine dihydrochloride to 6 to 12 year old pediatric seasonal allergic rhinitis patients resulted in about 2-fold the systemic exposure (AUC) observed when 5 mg of levocetirizine dihydrochloride was administered to healthy adults. Therefore, in children 6 to 11 years of age the recommended dose of 2.5 mg once daily should not be exceeded. In a population pharmacokinetics study the administration of 1.25 mg once daily in children 6 months to 5 years of age resulted in systemic exposure comparable to 5 mg once daily in adults. [see Dosage and Administration (2.2); Clinical Studies (14); and Clinical Pharmacology (12.3)].

Pediatric use information in pediatric patients (age 6 months to 5 years) is approved for UCB Inc.’s levocetirizine dihydrochloride drug product. However, due to UCB Inc.’s marketing exclusivity rights; this drug product is not labeled for such use in those pediatric patients.

geriatric use

Clinical studies of levocetirizine dihydrochloride for each approved indication did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently than younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.

renal impairment

Levocetirizine dihydrochloride is known to be substantially excreted by the kidneys and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection and it may be useful to monitor renal function [see Dosage and Administration (2) and Clinical Pharmacology (12.3)].

hepatic impairment

As levocetirizine is mainly excreted unchanged by the kidneys, it is unlikely that the clearance of levocetirizine is significantly decreased in patients with solely hepatic impairment [see Clinical Pharmacology (12.3)].
