Drugs Home > Levocetirizine Dosing

Levocetirizine dosing guidelines take several factors into account, such as age and existing medical conditions. For adults and children who are at least 12 years old, the recommended dose is 5 mg once daily in the evening. For children ages 6 to 11, the levocetirizine dose is usually 2.5 mg once daily in the evening.

Levocetirizine Dosing: An Introduction

The dose of levocetirizine dihydrochloride (Xyzal®) that your healthcare provider recommends will vary, depending on a number of factors, including:
  • Your age
  • Other medical conditions you may have
  • Other medications you may be currently taking.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

Levocetirizine Dosing for Adults and Older Children

The recommended dose of levocetirizine for most adults and children who are at least 12 years old is levocetirizine 5 mg once daily in the evening. Some people may find that a lower dose (levocetirizine 2.5 mg once daily in the evening) is also effective. If you have kidney disease, you should consult your healthcare provider before taking the drug, as you may need a lower dosage.

Levocetirizine Dosing for Children

The recommended dose of levocetirizine for children ages 6 to 11 is levocetirizine 2.5 mg (half a tablet or one teaspoonful of liquid) once daily in the evening.

General Information on Dosing With Levocetirizine

Considerations for people taking levocetirizine include the following:
  • The medication comes in tablet and liquid form. It is usually taken once a day in the evening.
  • You can take levocetirizine with or without food. If the medication bothers your stomach, try taking it with food.
  • If necessary, levocetirizine tablets may be broken in half.
  • Try to take levocetirizine at the same time each day to maintain an even level in your blood.
  • Some people may need to take the medication all year long, while others take it only during allergy season.
  • For the medication to work properly, it must be taken as prescribed. Levocetirizine will not work if you stop taking it.
  • If you are unsure about anything related to your dosage or levocetirizine dosing in general, please talk with your doctor, nurse, or pharmacist.
