L-Cetriver 10 Tablet contains Levocetirizine 10 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, including seasonal and perennial types, as well as chronic idiopathic urticaria characterized by itching and hives. L-Cetriver 10 provides rapid onset of action with sustained efficacy, improving patient comfort by reducing sneezing, nasal congestion, rhinorrhea, and pruritus. It is generally well tolerated, with a low incidence of sedation compared to first-generation antihistamines. The recommended dosage for adults and adolescents over 12 years is one tablet once daily, preferably in the evening. Caution is advised in patients with renal impairment, and dosage adjustments may be necessary. L-Cetriver 10 should be used under medical supervision, especially in pregnant or lactating women. Patients are advised to avoid alcohol and other central nervous system depressants during treatment. This medication offers effective symptomatic relief for allergic conditions with a favorable safety profile.
