Levocetirizine Dihydrochloride (5 mg)
Second-generation antihistamineLevocetirizine is the active R-enantiomer of cetirizine. It acts as a potent, selective antagonist at peripheral H1 histamine receptors. By competitively binding to these receptors, it prevents histamine released by mast cells during allergic reactions from triggering itchy, swollen, or inflamed tissues.
