Lezyncet Tablet contains Levocetirizine 5mg, a third-generation non-sedating antihistamine used primarily for the treatment of allergic conditions. Levocetirizine is the active enantiomer of cetirizine and exerts its therapeutic effects by selectively inhibiting peripheral H1 histamine receptors, thereby reducing the symptoms associated with allergic rhinitis, chronic idiopathic urticaria, and other allergic manifestations. The medication is indicated for the relief of nasal and ocular symptoms such as sneezing, rhinorrhea, nasal congestion, and itching, as well as for the management of skin-related allergic reactions including pruritus and hives. Lezyncet Tablet demonstrates rapid onset of action and provides sustained symptom control with once-daily dosing. It is generally well tolerated, with a low incidence of sedation compared to first-generation antihistamines. Common adverse effects may include headache, dry mouth, and fatigue, though these are typically mild and transient. Lezyncetirizine is contraindicated in patients with known hypersensitivity to the drug or its components and should be used cautiously in individuals with renal impairment, with dose adjustments as necessary. Lezyncet Tablet offers an effective and convenient therapeutic option for patients requiring long-term management of allergic conditions.
