Adults and children 12 years and older should take one 10mg tablet of Zyrtec once daily. For optimal effect, take it at the same time each day.
Children Under 12
Zyrtec 10mg tablets are not recommended for children under 12. Consult your doctor or pharmacist for appropriate dosage options for younger children. They may recommend a different formulation of cetirizine with a lower dosage.
Missed Dose
If you miss a dose, take it as soon as you remember unless it is almost time for your next dose. Do not take a double dose to make up for a missed one. Follow the prescribed dosage instructions consistently.
Specific Conditions
Kidney problems can affect how your body processes cetirizine. Individuals with impaired kidney function might need a dosage adjustment. Always discuss your medical history, including kidney health, with your doctor before starting Zyrtec.
Storage
Store Zyrtec tablets at room temperature, away from moisture and direct sunlight. Keep them out of reach of children.
