Cetirizine Dosage in Infants

Dosage and Administration

• The American Academy of Pediatrics recommends using oral drops for precise dosing based on weight in infants 1
• The formulation of cetirizine should be based on oral drops for accurate dosing in infants 1

Safety Considerations

• Approximately 13.7% of patients experience sedation compared to 6.3% with placebo, according to the Praxis Medical Insights 1, 2
• Sedation is a significant risk even at standard doses, and patients should be monitored, especially those with low body mass 3

Contraindications and Precautions

• The European Medicines Agency recommends avoiding cetirizine in patients with severe renal impairment (creatinine clearance <10 mL/min) 1
• In patients with moderate renal impairment (creatinine clearance 10-50 mL/min), the dose should be halved 1

Diagnostic Considerations

• The Journal of Allergy and Clinical Immunology advises against using allergy testing panels or sIgE tests for foods other than peanuts due to low positive predictive value 4
