What is Xyzal?

The antihistamine Xyzal minimises the negative effects of histamine, a natural chemical in the body. Histamine can cause symptoms such as nasal congestion or itchy hives.

Xyzal helps treat the symptoms of all-year (perennial) allergies in children at least 6 months old.

It can also be used for treating swelling and itching due to chronic urticaria (hives) in adults and young children who are at least 6 months old.


Before you take Xyzal, consult your physician, whether you suffer from kidney disease, liver illness, or gallbladder trouble.

It is crucial not to give your child more than the recommended dosage of Xyzal. Children's bodies absorb twice the same dose of levocetirizine as adults' bodies.

Follow all the instructions on the label of your medication and the package. Inform your health care providers about your medical issues, allergies, and the medicines you are taking.
