If your skin is damaged or your immune system detects a foreign substance, histamine is released from mast cells.The histamine binds to special sites (receptors) on other cells, called H1 receptors.Antihistamines work by physically blocking the H1 receptors, stopping histamine from reaching its target.This decreases your body's reaction to allergens and therefore helps to reduce the troublesome symptoms associated with allergy.While both types of medicine block the actions of histamine, they work on different receptors in different systems of the body.
