Route-Specific Dosing

• For children aged 6 to 12 years, the American Academy of Pediatrics recommends a dose of 5 mg administered intramuscularly or intravenously slowly, as outlined in anesthesia guidelines for managing suspected anaphylactic reactions 1
• The dosing for children aged 6 to 12 years is specifically 5 mg administered intramuscularly or intravenously slowly, according to the American Society of Anesthesiologists 1

Important Safety Considerations

• The British Journal of Dermatology confirms that currently licensed antihistamines, including chlorpheniramine, are not contraindicated in children 12 years and older, but the American Academy of Pediatrics recommends caution 2
• The American Academy of Pediatrics advises against using chlorpheniramine for common cold symptoms in children, as efficacy has not been established for upper respiratory infections, and recommends use only for clear allergic indications such as allergic rhinitis or urticaria as diagnosed by a healthcare professional 3
