L Hist Tablet contains Levocetirizine 5mg, 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 histamine H1-receptors, effectively inhibiting the effects of histamine, a key mediator in allergic reactions. This action helps alleviate symptoms such as sneezing, nasal congestion, rhinorrhea, and itching associated with allergic rhinitis, as well as urticaria and other skin manifestations of allergy. L Hist Tablet is indicated for the management of seasonal and perennial allergic rhinitis, chronic idiopathic urticaria, and other histamine-mediated hypersensitivity conditions. The 5mg dosage provides effective symptom relief with a favorable safety profile, exhibiting minimal sedative effects compared to first-generation antihistamines. It is generally well-tolerated, with common adverse effects including mild headache, dry mouth, and fatigue. L Hist Tablet should be administered once daily, with dosage adjustments considered in patients with renal impairment. It is contraindicated in individuals with known hypersensitivity to levocetirizine or cetirizine. As with all medications, consultation with a healthcare professional is recommended prior to use to ensure suitability and to discuss potential drug interactions.
