Cetirizine Dosage: An Introduction
- Your age
- The severity of your symptoms
- Other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
Cetirizine Dosage for Adults and Older Children
The recommended dose of
cetirizine for most adults and children age six and over is cetirizine 10 mg once daily. For mild symptoms, cetirizine 5 mg once daily may be sufficient. Check with your healthcare provider if you have liver or kidney disease, as a lower dose may be recommended.
The label of cetirizine recommends that people age 65 and older check with their healthcare providers before taking the drug in order to determine the best dose. It is common for liver and kidney function to decline with age, and a lower cetirizine dosage may be recommended.
Cetirizine Dosage for Young Children
The recommended dose of cetirizine for children ages two through five is cetirizine 2.5 mg once daily. This dose is equivalent to half a teaspoonful (2.5 mL) of cetirizine syrup. Consult your child's healthcare provider if your child has liver or kidney problems, as a lower dosage may be recommended. Only the syrup form, designed to treat
allergies, is approved and labeled for this age group. Other cetirizine products are not approved for this young age range.
