Uses For Xyzal
Levocetirizine is an antihistamine used to relieve the symptoms of hay fever and hives of the skin. It works by preventing the effects of a substance called histamine, which is produced by the body. Histamine can cause itching, sneezing, runny nose, and watery eyes. It can close up the bronchial tubes (air passages of the lungs) and make breathing difficult. Histamine can also cause some persons to have hives, with severe itching of the skin.
This medicine is available only with your doctor's prescription.
Before Using Xyzal

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of levocetirizine in children. Safety and efficacy have not been established in infants younger than 6 months of age.
Use in children 6 months to 11 years of age with kidney disease is not recommended.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of levocetirizine in the elderly. However, 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.
