Levocetirizine is an antihistamine or anti-allergic medication. It alleviates sneezing, runny nose, and allergic skin caused by allergies and hay fever (seasonal allergy). An allergy is an immune system reaction to a foreign element that is usually not harmful to your body. These foreign elements are referred to as 'allergens.' The severity of allergic reactions varies from person to person. Some people are allergic to certain foods, as well as seasonal allergies such as hay fever, pollen, or pet dander. Cough is a common allergy symptom that occurs as a reflex action in the throat when mucus or a foreign irritant enters the respiratory system.Disclaimer:For More Information Contact Your Physician
