Quzyttir
(Cetirizine Hydrochloride)Dosage & Administration
QUZYTTIR is a single use injectable product for intravenous administration only. The recommended dosage regimen is once every 24 hours as needed for treatment of acute urticaria. Administer QUZYTTIR as an intravenous push over a period of 1 to 2 minutes. QUZYTTIR is not recommended in pediatric patients less than 6 years of age with impaired renal or hepatic function
The safety and efficacy of QUZYTTIR have been established in patients 6 months to 17 years of age. The efficacy of QUZYTTIR for the treatment of acute urticaria down to 6 months of age is based on extrapolation of the efficacy of QUZYTTIR in adults with acute urticaria
The safety of QUZYTTIR in children 6 months to 17 years of age is supported by safety information from placebo-controlled clinical trials with oral cetirizine hydrochloride in patients 6 months of age and older
Because of the absence of pharmacokinetic and safety information for cetirizine hydrochloride in children below 6 years of age with impaired renal or hepatic function, the use of QUZYTTIR in this impaired patient population is not recommended
The safety and efficacy of QUZYTTIR in patients less than 6 months of age has not been established.
If using as an antihistamine prior to infusion product administration, refer to infusion product prescribing information for instructions.

QUZYTTIR is a sterile, clear, colorless, non-pyrogenic, isotonic aqueous solution of cetirizine hydrochloride for intravenous injection; supplied in 2 mL size amber glass vials for single use. Each 2 mL size amber glass vial contains 1 mL drug solution with 10 mg cetirizine hydrochloride (equivalent to 8.42 mg of cetirizine).
There are no adequate and well-controlled studies in pregnant women with cetirizine hydrochloride the active ingredient in QUZYTTIR. In animal reproduction studies, there was no evidence of fetal harm with administration of cetirizine hydrochloride by the oral route to pregnant mice, rats, and rabbits, during the period of organogenesis, at doses that were 45 times and higher than the maximum recommended human dose (MRHD) in adults. In rats treated during late gestation and the lactation period, cetirizine hydrochloride had no effects on pup development at oral doses up to approximately 30 times the MRHD in adults. In mice treated during late gestation and the lactation period, cetirizine hydrochloride administered by the oral route to the dams had no effects on pup development at a dose that was approximately 10 times the MRHD in adults; however, lower pup weight gain during lactation was observed at a dose that was 45 times the MRHD in adults (See
In a prenatal and postnatal development (PPND) study conducted in mice, cetirizine hydrochloride was administered at oral doses up to 96 mg/kg/day from gestation day 15 through lactation day 21. Cetirizine hydrochloride lowered pup body weight gain during lactation at an oral dose in dams that was approximately 45 times the MRHD (on a mg/m2basis 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 10 times the MRHD (on a mg/m2basis with a maternal oral dose of 24 mg/kg/day). In a PPND study conducted in rats, cetirizine hydrochloride was administered at oral doses up to 180 mg/kg/day from gestation day 17 to lactation day 22. Cetirizine hydrochloride did not have any adverse effects on rat dams or offspring development at doses up to approximately 30 times the MRHD (on a mg/m2basis with a maternal oral dose of 30 mg/kg/day). Cetirizine hydrochloride caused excessive maternal toxicity at an oral dose in dams that was approximately 180 times the MRHD (on a mg/m2basis with a maternal oral dose of 180 mg/kg/day).
The use of QUZYTTIR is contraindicated in patients with a known hypersensitivity to cetirizine hydrochloride or any of its ingredients, levocetirizine, or hydroxyzine.
In clinical trials with QUZYTTIR and cetirizine hydrochloride tablets, the occurrence of somnolence/sedation has been reported in some patients. Exercise due caution when driving a car or operating potentially dangerous machinery. Avoid concurrent use of QUZYTTIR with alcohol or other CNS depressants because additional reduction in alertness and additional impairment of CNS performance may occur.
