Loratadine is a non-drowsy antihistamine primarily used to relieve symptoms associated with seasonal and perennial allergic rhinitis, such as sneezing, runny nose, itchy or watery eyes, and itching of the nose or throat. It is also used to treat symptoms of chronic idiopathic urticaria (hives), including itching and reduction in the size and number of hives. Loratadine is available over-the-counter and by prescription, typically in oral forms such as tablets, orally disintegrating tablets, and syrup. It is classified as a second-generation antihistamine, meaning it is generally less sedating than older, first-generation antihistamines. (MedlinePlus, DrugBank)
