How does this medication work? What will it do for me?

Desloratadine belongs to a group of medications known as antihistamines, specifically the class known as H1-receptor antagonists. During an allergic reaction, the body produces a chemical called histamine, which causes allergy symptoms such as hives, runny nose, sneezing, itchy throat, congestion, and itchy watery eyes. Desloratadine works by blocking the action of histamine in the body.

This medication is used to relieve the symptoms of seasonal and year-round allergies including nasal congestion, sneezing, runny nose, itchy nose, itchy palate, coughing, and itchy watery red eyes. It is also use to relieve the symptoms of allergic skin conditions (e.g., chronic idiopathic urticaria) such as skin itch and hives. Desloratadine usually starts to work within 75 minutes and lasts for 24 hours.
