LCZ Tablet contains Levocetirizine 5mg, a third-generation non-sedative antihistamine used primarily for the relief of allergic symptoms. Levocetirizine is the active enantiomer of cetirizine and functions as a selective antagonist of peripheral H1 histamine receptors, thereby inhibiting the effects 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 effective relief from symptoms such as sneezing, nasal congestion, runny nose, itchy or watery eyes, and hives. LCZ Tablet offers rapid onset of action with a favorable safety profile, minimizing sedation and central nervous system side effects commonly associated with first-generation antihistamines. It is administered orally, usually once daily, with or without food, and is suitable for adults and children over the age of six. Caution is advised in patients with renal impairment, and dosage adjustments may be necessary. LCZ Tablet should be used under medical supervision, especially in individuals with pre-existing medical conditions or those taking concomitant medications to avoid potential drug interactions. Overall, LCZ Tablet is a well-tolerated and effective option for managing allergic conditions, improving patient quality of life.
