Levozet 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 responses. This medication is indicated for the relief of symptoms associated with allergic rhinitis, including sneezing, nasal congestion, rhinorrhea, and itchy or watery eyes, as well as chronic idiopathic urticaria characterized by hives and itching. Levozetirizine exhibits rapid absorption with peak plasma concentrations achieved within one hour of oral administration, and it has a favorable safety profile with minimal sedative effects compared to first-generation antihistamines. The recommended dosage for adults and children over 12 years is one tablet (5mg) once daily, with adjustments made for patients with renal impairment. Caution is advised in patients with severe renal dysfunction and in those who may be sensitive to antihistamines. Levozetirizine should be used under medical supervision, and patients are advised to avoid alcohol and other central nervous system depressants during treatment.
