Allergic response reduce the severity of the allergic response. Often these treatments include an antihistamine oral pill, nasal spray, or eye drops. Other treatments include an allergy shot, which keep the allergic response to a minimum. For more severe reactions an epinephrine injection is carried around. This injection will be taken if the person is going into anaphylactic shock. The best treatment is avoidance of each allergen. 1) Allergies (2011) reviewed by A.D.A.M.

Allergic inflammation hours and is mediated by mast cells) should not be confused with delayed hypersensitivity Type IV allergic reaction (which takes 48–72 hours to develop and is mediated by T cells). The products of the early phase reaction include chemokines and molecules that act on endothelial cells and cause them to express Intercellular adhesion molecule (such as vascular cell adhesion molecule and selectins), which together result in the recruitment and activation of leukocytes from the blood into the site of the allergic reaction. Typically, the infiltrating cells observed in allergic reactions contain a high proportion of lymphocytes, and especially, of eosinophils.
