LC Sure 10 Tablet contains Levocetirizine 10 mg, a potent second-generation antihistamine used primarily for the relief of allergy symptoms. Levocetirizine is the active enantiomer of cetirizine and functions as a selective antagonist of peripheral H1 histamine receptors, thereby inhibiting the effects of histamine, a key mediator in allergic reactions. This medication is indicated for the treatment of allergic rhinitis, including seasonal and perennial forms, as well as chronic idiopathic urticaria characterized by itching and hives. LC Sure 10 Tablet provides effective symptom control with a reduced risk of sedation compared to first-generation antihistamines, due to its limited penetration of the blood-brain barrier. The recommended dosage is typically one tablet once daily, which ensures sustained relief of symptoms such as sneezing, nasal congestion, runny nose, and itching. It is well-tolerated in adults and adolescents over 12 years of age; however, caution is advised in patients with renal impairment, where dose adjustment may be necessary. Common side effects include headache, dry mouth, and fatigue, though these are generally mild and transient. LC Sure 10 Tablet should be used under medical supervision, especially in pregnant or breastfeeding women.
