Laveta 5mg Tablet contains Levocetirizine, a third-generation non-sedative antihistamine used primarily for the treatment of allergic conditions. Levocetirizine is the active enantiomer of cetirizine and functions by selectively inhibiting peripheral H1 histamine receptors, thereby reducing the effects of histamine-mediated allergic symptoms. This medication is indicated for the relief of symptoms associated with seasonal allergic rhinitis, perennial allergic rhinitis, and chronic idiopathic urticaria, including sneezing, nasal congestion, runny nose, itchy and watery eyes, and skin rashes or hives. Laveta 5mg is well-tolerated and has a lower incidence of sedation compared to first-generation antihistamines, making it suitable for daytime use. The recommended dosage for adults and children over 12 years is one tablet (5 mg) once daily, with dose adjustments necessary in patients with renal impairment. Common adverse effects may include headache, dry mouth, and fatigue, though these are generally mild and transient. Caution is advised when administered concomitantly with CNS depressants or alcohol. Laveta 5mg Tablet should be used under medical supervision, particularly in patients with a history of renal dysfunction or hypersensitivity to levocetirizine or related compounds.
