Seasonal allergic rhinitis (SAR), commonly referred to as "hay fever" or "outdoor allergies," is the most common form of allergic rhinitis. By definition, SAR includes allergies to seasonal pollens like grass, trees, and weeds, as well as mold. Perennial Allergic Rhinitis (PAR) is sometimes referred to as "year round" or "indoor allergies" and is characterized by allergic symptoms that last longer than four weeks. House dust mites, animal dander, and mold most commonly trigger PAR. Chronic Idiopathic Urticaria (CIU) is most commonly known as "chronic hives of unknown origin" and is defined as the occurrence of daily, or almost daily, wheals and itching for at least six weeks with no obvious causes.

About XYZAL(R)

Indications and Important Safety Information

XYZAL(R) is indicated for the relief of symptoms associated with allergic rhinitis (seasonal and perennial) and the treatment of uncomplicated skin manifestations of chronic idiopathic urticaria in adults and children 6 years of age and older.

The use of XYZAL(R) is contraindicated in: patients with a known hypersensitivity to levocetirizine or any of the ingredients of XYZAL or to cetirizine (observed reactions range from urticaria to anaphylaxis); patients with end-stage renal impairment at less than 10 mL/min creatinine clearance or patients undergoing hemodialysis; and pediatric patients aged 6 to 11 years with impaired renal function.

Patients should be cautioned against engaging in hazardous occupations requiring complete mental alertness and motor coordination, such as operating machinery or driving a motor vehicle, after ingestion of XYZAL(R). Concurrent use of XYZAL(R) with alcohol or other central nervous system (CNS) depressants should be avoided because additional reductions in alertness and additional impairment of CNS performance may occur.
