Each year about 200 adults and children in the United States die from food-related anaphylaxis, an extreme reaction that causes swelling of the throat and bronchial passages, shock, and a severe drop in blood pressure.

In a very few cases, milk allergy can cause anaphylaxis.

Anaphylaxis is thought to result from antigen-antibody interactions on the surface of mast cells, connective tissue cells that are believed to contain a number of regulatory, or mediator, chemicals.

Although children may lose their sensitivity to penicillin, if the reaction was urticarial or anaphylaxis, they are not re-challenged with the drug for safety reasons (i.e. it is not possible to predict who has lost sensitivity).

Some children have a very severe allergic reaction, called anaphylaxis, with more serious symptoms.

General - hypersensitivity including anaphylaxis, has been reported.

Nuts Can cause urticaria in children and go on to cause a serious allergy - anaphylaxis.

The possibility of causing an exaggerated allergic response, a dangerous condition known as anaphylaxis, does exist.

Anaphylaxis can result in difficulty breathing and a sharp drop in blood pressure.

Skin tests should never include a substance to which the individual has had severe allergic reactions or that has previously caused anaphylaxis.

Exposure to new or unsuspected allergens in any test carries the risk of anaphylaxis.

It is critical that physicians provide education about how to recognize anaphylaxis and tell patients what to do if it occurs at home.

Nut allergies and shellfish, however, seem to be the most documented triggers for anaphylaxis.

Nevertheless, anaphylaxis is not limited to those foods.

The rarest and most severe reaction, called anaphylaxis, produces immediate shock and can be fatal.

Multiple stings can have much more severe consequences, such as anaphylaxis, a life-threatening allergic reaction that occurs in children who are hypersensitive to the venom.

Children who are allergic to such stings, however, can experience severe and occasionally fatal anaphylaxis (life-threatening allergic reaction to bites and stings).

Anaphylaxis is a severe, sudden, and potentially fatal allergic reaction to a foreign substance or antigen that affects multiple systems of the body.

Anaphylaxis is a severe, whole-body allergic reaction.

Anaphylactoid (meaning "anaphylactic-like") reactions are similar to those of true anaphylaxis but do not require an IgE immune reaction.

It can produce itching, lightheadedness, hives, and anaphylaxis.

The symptoms of anaphylaxis may occur within seconds of exposure, or be delayed 15 to 30 minutes and sometimes even an hour or more later, if the allergen is aspirin or other similar drugs.

Children at risk for anaphylaxis should also wear a Medic Alert bracelet or necklace or carry a medical emergency card with them at all times that clearly describes their allergy.

Premedication is also helpful in preventing anaphylaxis from x-ray dyes; also there may be alternative dyes available for use that are less likely to cause reactions.

The risk of anaphylaxis sometimes diminishes over time if there are no repeated exposures or reactions.

Insect stings and the intravenous injection of certain drugs are the most common causes of anaphylaxis, the most severe and frightening allergic response.

Although it is rare, several hundred Americans die of anaphylaxis every year.

Unlike drug allergies, sensitivities often occur upon first exposure to a drug and do not lead to anaphylaxis.
