Leeco 5mg Tablet contains Levocetirizine dihydrochloride, an active antihistamine agent used primarily for the relief of allergic symptoms. Levocetirizine is a selective, third-generation non-sedating H1 receptor antagonist that effectively inhibits the effects of histamine, a chemical responsible for allergy manifestations such as sneezing, rhinorrhea, nasal congestion, and itching. This medication is indicated for the treatment of allergic rhinitis, including both seasonal and perennial forms, as well as chronic idiopathic urticaria characterized by itching and hives. Leeco 5mg Tablet offers rapid onset of action and sustained symptom control with a favorable safety profile, minimizing sedation and anticholinergic side effects commonly associated with first-generation antihistamines. The recommended dosage for adults and children over 12 years is one tablet daily, preferably in the evening, with dose adjustments required in patients with renal impairment. Contraindications include hypersensitivity to levocetirizine or any component of the formulation. Caution is advised in patients with renal dysfunction, and concurrent use with central nervous system depressants should be monitored. Leeco 5mg Tablet should be used under medical supervision to ensure optimal therapeutic outcomes and to monitor for potential adverse reactions such as headache, dry mouth, and fatigue.
