Hicet Tablet contains Cetirizine 10mg, a second-generation antihistamine used for the relief of allergy symptoms. Cetirizine selectively inhibits peripheral H1 histamine receptors, thereby reducing the effects of histamine, a substance responsible for allergic manifestations. 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. Hicet Tablet provides effective symptomatic relief from sneezing, nasal discharge, nasal congestion, itching of the nose and throat, and ocular symptoms such as itching and redness. Due to its minimal penetration of the blood-brain barrier, Cetirizine is associated with a lower incidence of sedation compared to first-generation antihistamines. The recommended dosage for adults and children over 12 years is one tablet (10mg) once daily, which can be adjusted based on clinical response and patient tolerance. Caution is advised in patients with renal impairment, and dose adjustments may be necessary. Common adverse effects include headache, dry mouth, and fatigue, which are generally mild and transient. Hicet Tablet should be used under medical supervision, particularly in pregnant or lactating women, and patients should avoid concomitant use with other sedative medications unless directed by a healthcare professional.
