Xyzal 10mg Tablet contains Levocetirizine 10mg, a third-generation non-sedative antihistamine used primarily for the relief of allergy symptoms. Levocetirizine selectively inhibits peripheral H1 receptors, thereby reducing the effects of histamine, a key mediator in allergic reactions. This medication is indicated for the treatment of allergic rhinitis, including seasonal and perennial forms, as well as chronic idiopathic urticaria characterized by itching and hives. Xyzal provides rapid onset of action and sustained symptom control, improving patient quality of life by alleviating nasal congestion, sneezing, rhinorrhea, and ocular itching. It is generally well tolerated, with a low incidence of sedation compared to first-generation antihistamines. The recommended dose is one 10mg tablet once daily, preferably in the evening, with adjustments made for patients with renal impairment. Caution is advised in individuals with severe renal dysfunction, and use during pregnancy or lactation should be under medical supervision. Common adverse effects may include headache, dry mouth, and fatigue, though these are typically mild and transient. Xyzal 10mg Tablet should be used as part of a comprehensive allergy management plan, and patients are advised to consult healthcare professionals before initiating therapy.
