Lazine Tablet contains Levocetirizine 5mg, a third-generation non-sedating antihistamine used primarily for the relief of allergic symptoms. Levocetirizine is the active enantiomer of cetirizine and functions as a selective antagonist of peripheral histamine H1-receptors, thereby inhibiting the effects of histamine released during allergic reactions. Lazine is indicated for the treatment of allergic rhinitis, including seasonal and perennial allergic rhinitis, as well as chronic idiopathic urticaria characterized by itching and hives. The medication provides rapid onset of action and sustained symptom relief, improving patient comfort and quality of life. Levocetirizine is well-tolerated with a low incidence of sedation compared to first-generation antihistamines, making it suitable for daytime use. The recommended dose for adults and children over 12 years is one 5mg tablet once daily, with dosage adjustments required for patients with renal impairment. Lazine should be used with caution in individuals with a history of hypersensitivity to levocetirizine or cetirizine. Common adverse effects include headache, dry mouth, and fatigue. Patients are advised to consult healthcare professionals before initiating therapy, especially if pregnant, breastfeeding, or taking other medications to avoid potential interactions.
