The severity of such an allergic reaction, which often requires injections of epinephrine, also known as EpiPen or Twinject auto-injector. Character of anaphylaxis is such that the reaction may seem subsidence, but may recur throughout a long period. Subjects come into contact with the skin, such as latex, are also common causes of allergic reactions or contact dermatitis or eczema. allergies often cause skin rashes or swelling and inflammation within the skin, what is called a characteristic wheal and flare reaction of urticaria and angioedema.

In people who are not allergic, just mucus in the nose moves foreign neck, where they are swallowed or coughed on. But something happens to a person who is sensitive to airborne allergens. Once the allergen lands on the mucous membranes lining the nose, a chain reaction that leads the mast cells in these tissues to release histamine and other chemicals. These powerful chemicals contact certain cells that line the small blood vessels in the nose. This allows fluids to escape, causing the nasal passages to swell, causing nasal congestion.

Anaphylaxis in very rare cases, allergies can cause a severe allergic reaction called anaphylactic shock, which can be fatal. Most allergic reactions occur in the local tissues in a particular body part such as nose, eyes or skin. In anaphylaxis, allergic reactions involving the entire body and usually occurs within minutes of contact with a specific allergen.
