Levapp 5mg Tablet contains Levocetirizine 5mg, a third-generation non-sedative antihistamine used primarily for the treatment of allergic conditions. Levocetirizine is an active enantiomer of cetirizine, exhibiting selective antagonism of peripheral H1 histamine receptors, thereby effectively reducing symptoms associated with allergic rhinitis, chronic idiopathic urticaria, and other histamine-mediated allergic disorders. The medication works by inhibiting the effects of histamine, a chemical responsible for allergy symptoms such as sneezing, nasal congestion, itching, and watery eyes. Levapp 5mg is indicated for adults and children over the age of six, providing rapid relief from allergic manifestations with minimal sedative effects due to its reduced penetration of the blood-brain barrier. The usual dosage is one tablet once daily, which can be adjusted based on clinical response and patient tolerance. Levapp is generally well-tolerated, with adverse effects including mild headache, dry mouth, and fatigue reported infrequently. It is contraindicated in patients with known hypersensitivity to levocetirizine or any of its excipients. Caution is advised in patients with renal impairment, where dose adjustment may be necessary. Levapp 5mg Tablet offers a convenient and effective option for managing allergic symptoms, improving patient quality of life.
