LCZ 10 Tablet contains Levocetirizine 10 mg, a third-generation non-sedative antihistamine used primarily for the relief of allergic symptoms. Levocetirizine is a selective antagonist of peripheral H1 receptors, effectively inhibiting the action of histamine, a key mediator in allergic reactions. This medication is indicated for the treatment of allergic rhinitis, including seasonal and perennial types, as well as chronic idiopathic urticaria, providing symptomatic relief from sneezing, nasal congestion, rhinorrhea, itching, and hives. LCZ 10 Tablet offers rapid onset of action with a favorable safety profile, minimizing sedation and other central nervous system effects commonly associated with first-generation antihistamines. It is administered orally, typically once daily, and dosage adjustments may be necessary in patients with renal impairment. Caution is advised in individuals with a history of hypersensitivity to Levocetirizine or related compounds. Common adverse effects include headache, dry mouth, and fatigue, although these are generally mild and transient. LCZ 10 Tablet should be used under medical supervision, especially in pregnant or lactating women, and in patients with pre-existing medical conditions. Overall, LCZ 10 Tablet is an effective and well-tolerated option for managing allergic conditions requiring H1 receptor blockade.
