Xyzal Oral Solution is an antihistamine that relieves allergy symptoms such as watery eyes, runny nose, itching eyes/nose, and sneezing. It is also used to relieve itching and hives. It works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction.

Take Xyzal Oral Solution exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Use Xyzal exactly as directed.

Do not give a child more than the prescribed dose of this medicine. A child's body absorbs twice the same dose size of levocetirizine as an adult's. Taking more of this medication may cause severe drowsiness.

Xyzal is usually taken in the evening, with or without food. Measure liquid medicine carefully. Use the dosing syringe provided or a medicine dose-measuring device (not a kitchen spoon).

Call your doctor if your symptoms do not improve, if they get worse, or if you also have a fever.

  Use is not recommended in children six months to 11 years of age with kidney disease.
• Geriatric
  Elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving levocetirizine.
