Oriel 10 Tablet contains Levocetirizine 10 mg, a potent second-generation antihistamine primarily used for the relief of allergy symptoms. Levocetirizine selectively inhibits peripheral H1 receptors, thereby reducing 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 characterized by itching and hives. Oriel 10 Tablet offers rapid onset of action and a long duration of effect, providing sustained symptom control with once-daily dosing. Unlike first-generation antihistamines, Levocetirizine exhibits minimal sedative effects due to limited penetration across the blood-brain barrier, enhancing patient compliance and safety. The drug is well tolerated, with common adverse effects including mild headache, dry mouth, and fatigue. Oriel 10 Tablet should be used with caution in patients with renal impairment, and dosage adjustments may be necessary. It is contraindicated in individuals with known hypersensitivity to Levocetirizine or Cetirizine. As with all medications, it is recommended to use Oriel 10 Tablet under medical supervision, adhering to prescribed dosages to achieve optimal therapeutic outcomes while minimizing potential risks.
