Before you can start experiencing the powerful relief of the X-Factor™, you need a prescription from your doctor. So speak with your doctor to see if XYZAL® is right for you—before another allergy season has you sneezing and suffering.

XYZAL^® (levocetirizine dihydrochloride) is a prescription medication used to treat the symptoms of year round allergies, as well as a treatment for chronic hives and rashes of unknown cause (also known as chronic idiopathic urticaria) in patients 6 months of age and older, and symptoms of seasonal allergies in patients 2 years of age and older.

Do not take XYZAL if you are allergic to XYZAL, cetirizine or ZYRTEC^®. Be sure to tell your doctor if you have kidney disease. Children 6 months to 11 years of age with impaired kidney function should not take XYZAL. Patients taking XYZAL should avoid operating machinery or driving a motor vehicle. Taking XYZAL with alcohol or sedatives should be avoided. Take XYZAL at bedtime. Do not increase the dose due to increased risk of sleepiness.

In patients 12 years of age and older, side effects may include sleepiness, tiredness, sore throat and dry mouth. In children 6-12 years of age, side effects may include fever, cough, sleepiness and nose bleeds. In children 1-5 years of age, side effects may include fever, diarrhea, vomiting, and ear infections. In children 6 months to 11 months of age, side effects may include diarrhea and constipation.
