Occetiz 5 Tablet contains Levocetirizine 5 mg, a third-generation non-sedative antihistamine used primarily for the relief of allergic symptoms. Levocetirizine is the active enantiomer of cetirizine and acts as a selective antagonist of peripheral H1 histamine receptors, effectively inhibiting the effects of histamine released during allergic reactions. This medication is indicated for the treatment of allergic rhinitis (both seasonal and perennial), chronic idiopathic urticaria, and other conditions characterized by histamine-mediated symptoms such as sneezing, nasal congestion, runny nose, itchy or watery eyes, and skin itching or hives. Occetiz 5 Tablet offers rapid onset of action with a favorable safety profile, minimal sedation, and a once-daily dosing regimen, enhancing patient compliance. It is well tolerated in both adults and children above six years of age. Caution is advised in patients with renal impairment, and dosage adjustments may be necessary. Occetiz should be used under medical supervision, especially in individuals with a history of hypersensitivity to levocetirizine or related compounds. Common side effects include headache, dry mouth, and fatigue, which are generally mild and transient. This medication should not be combined with other central nervous system depressants without consulting a healthcare professional.
