Levocetirizine may also be used for purposes not listed in this medication guide.

What is the most important information I should know about levocetirizine (Xyzal)?

You should not use this medication if you are allergic to levocetirizine or cetirizine (Zyrtec).

Do not take levocetirizine if you have end-stage kidney disease or if you are on dialysis. Any child younger than 12 years old with kidney disease should not take levocetirizine.

Before taking levocetirizine, tell your doctor if you have liver disease, kidney disease, or gallbladder problems.

It is very important not to give a child more than the prescribed dose of this medication. A child's body absorbs twice as much of the same dose size of levocetirizine as an adult's body.

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