Fexo
Fexo is a second-generation antihistamine that contains Fexofenadine. It works by selectively blocking peripheral H1 receptors, thereby preventing the actions of histamine, a substance in the body that causes allergic symptoms. Unlike older antihistamines, Fexo does not readily enter the brain, making it non-drowsy for most people.
