How does loratadine work to relieve allergy symptoms?
Loratadine is a second-generation antihistamine. It works by blocking the action of histamine, a substance produced by the body during an allergic reaction. Histamine is responsible for many allergy symptoms, such as sneezing, itching, runny nose, and watery eyes [3]. Loratadine is considered a non-drowsy antihistamine because it does not readily cross the blood-brain barrier, meaning it has less of a sedating effect compared to older antihistamines [3].
