In an allergic reaction, certain allergens invade the body with oversensitive immune system that can produce certain signs and symptoms. This reaction is primarily due to excessive secretion of a chemical known as Histamine. So the basic aim is to suppress this chemical in order to eliminate allergic symptoms. Fexofenadine does the same after being introduced in the body orally. This antihistamine drug negates selective H1-recpetor significantly to bring down the levels of histamine; thereby, giving quick relief from allergy.
