Levocetzime 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 as a selective antagonist of peripheral H1 histamine receptors, thereby inhibiting the effects of histamine released during allergic reactions. 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, rhinorrhea, itching, and hives. Levocetzime 5mg is well-tolerated with minimal sedative effects due to its reduced penetration of the blood-brain barrier. The recommended adult dose is 5 mg once daily, which can be adjusted based on clinical response and patient tolerance. Caution is advised in patients with renal impairment, and dosage adjustments may be necessary. Common adverse effects include headache, dry mouth, and fatigue, though these are generally mild and transient. Levocetzime should be used with caution in patients with a history of hypersensitivity to levocetirizine or any of its excipients. It is contraindicated in patients with severe renal impairment and should not be combined with other central nervous system depressants without medical supervision.
