For adults and children 6 years and older, the typical Zyrtec (cetirizine) dosage is 10 mg once daily. This single dose effectively manages allergy symptoms for most individuals. Remember to always consult the accompanying leaflet for complete instructions.
Children aged 2 to 5 years may require a lower dose, typically 5 mg once daily. However, precise dosage for younger children should always be determined by a pediatrician or other qualified healthcare professional. They can assess your child’s specific needs and recommend the safest and most appropriate amount.
Important Note: Never exceed the recommended dosage without consulting a doctor. While generally well-tolerated, exceeding the prescribed amount can lead to side effects. If you experience any unusual symptoms after taking Zyrtec, immediately contact your physician.
