Xoomax LC Tablet is a combination medication containing Levocetirizine 5mg and Montelukast 10mg, formulated for the management of allergic conditions such as allergic rhinitis and chronic urticaria. Levocetirizine, a third-generation non-sedative antihistamine, selectively inhibits peripheral H1 histamine receptors, thereby reducing symptoms like sneezing, nasal congestion, itching, and rhinorrhea. Montelukast, a leukotriene receptor antagonist, blocks the action of leukotrienes, inflammatory mediators involved in bronchoconstriction, mucus production, and edema, making it effective in preventing and treating asthma and allergic rhinitis. The synergistic effect of these two active ingredients provides comprehensive relief from allergic symptoms by targeting different pathways of the allergic response. Xoomax LC Tablet is typically prescribed once daily, preferably in the evening, to improve patient compliance and optimize therapeutic outcomes. It is well-tolerated with a low incidence of adverse effects, which may include headache, fatigue, dry mouth, or gastrointestinal discomfort. This combination therapy is contraindicated in patients with known hypersensitivity to either component and should be used cautiously in individuals with hepatic or renal impairment. Consultation with a healthcare professional is recommended before initiating therapy to ensure appropriate use and monitoring.
