What is this medication for?

Loratadine belongs to the class of medications called second-generation antihistamines. These medications work by blocking the action of one of the body's natural chemicals known as histamine. Histamine is responsible for many of the symptoms caused by allergies. Loratadine is used for the relief of symptoms associated with seasonal and chronic allergies, including sneezing, itchy and runny nose, tearing and redness of the eyes, as well as itching and hives. It starts working within 1-2 hours and lasts for 24 hours.
