Claritin (loratadine) is one of the most popularly prescribed antihistamines and is available over-the-counter. It prevents sneezing, runny nose, stuffiness, itching and watering of the eyes in those with allergic rhinitis. It is also used to alleviate skin allegies such as hives or urticaria by relieveing swollen, red, itchy patches of skin as well as other allergic inflammatory conditions. It is a second generation antihistamin that is minimally sedating. Its improved version is desloratadine, manufactured under the trade name, Clarinex, which is just as effective but with fewer side effects.
