Xyzal is primarily used for the treatment of seasonal or perennial allergies and chronic hives that are of unknown cause. The medication has been approved for use in adults and children as young as six years old. Some "off-label" Xyzal uses may include the treatment of hives or rashes that have a known cause (such as poison ivy).
Xyzal® (levocetirizine dihydrochloride) is a prescription medication approved to treat allergies and chronic hives that are due to unknown causes (known medically as chronic idiopathic urticaria).
Allergies are the immune system's specific reaction to normally harmless substances, such as pollens, certain foods, or medicines. Allergies can either be seasonal or perennial. Seasonal allergies (such as hay fever) occur at specific times of the year, while perennial allergies can occur throughout the year. Allergies can affect various parts of the body, and allergy symptoms are particularly common in the eyes, nose, throat, and lungs.
Combined with strategies to minimize a person's contact with allergens, allergy treatment can make life bearable for even the worst allergy sufferer. Treatment often includes allergy shots or medications. Xyzal is approved to treat both seasonal and perennial allergies in adults and children age six and older.
Xyzal is also approved for treating chronic idiopathic urticaria (chronic hives of unknown cause). Hives are red, raised welts on the skin. They are usually very itchy. Hives are commonly caused by allergies, although other factors (such as stress) can also cause them. Many people get hives chronically without knowing what causes them. Xyzal is approved to treat chronic hives of unknown cause in adults and children as young as six years old.
