A severe immediate life-threatening medical emergency that includes difficulty in breathing, lowering of blood pressure, and shock It is caused by a Type I hypersensitivity reaction
allergic reaction; an acute, generalized, and violent antigen-antibody reaction that can be rapidly fatal
a potent allergic reaction, characterized by vasodilation and smooth muscle contractions, which can result in death within seconds after exposure to the allergen
Severe, life-threatening allergic response characterized by lowered blood pressure, swelling, and hives
hypersensitivity reaction to the ingestion or injection of a substance (a protein or drug) resulting from prior contact with a substance
Systemic or generalized anaphylaxis, anaphylactic shock, a manifestation of immediate hypersensitivity in which exposure of a sensitized individual to a specific antigen or hapten results in life-threatening respiratory distress usually followed by vascular collapse and shock and accompanied by urticaria, pruritus, and angioedema Common agents causing anaphylaxis include Hymenoptera venom, pollen extracts, certain foods, horse and rabbit sera, heterologous enzymes and hormones, and certain drugs, such as penicillin and lidocaine (Dorland, 27th ed)
(ana-full-ax-is)- a type of allergic reaction that is sudden, severe, and involves your whole body It can be fatal
a sudden, severe, potentially life-threatening allergic reaction caused by food allergy, insect stings, or medications Symptoms can include hives, swelling (especially of the lips and face), difficulty breathing (either because of swelling in the throat or an asthmatic reaction), vomiting, diarrhea, cramping, and a drop in blood pressure
A life-threatening allergic reaction that involves the entire body Anaphylaxis may result in shock or death, and thus requires immediate medical attention
Anaphylaxis, or anaphylactic shock, is a severe, frightening and life-threatening allergic reaction The reaction, although rare, can occur after an insect sting or as a reaction to an injected drug - for example, penicillin or antitetanus (horse) serum Less commonly, the reaction occurs after a particular food or drug has been taken by mouth
Severe allergic response to a substance Symptoms include wheezing, itching, nasal congestion, hives, immediate intense burning of hands and feet, collapse with severe drop in blood pressure, loss of consciousness and cardiac arrest
Severe, immediate, potentially fatal bodily reaction to contact with a substance (antigen) to which the individual has previously been exposed. Often triggered by antiserum, antibiotics, or insect stings, the reaction's symptoms include skin flushing, bronchial swelling (with difficulty breathing), and loss of consciousness. Shock may follow. Milder cases may involve hives and severe headache. Treatment, consisting of injection of epinephrine, followed by antihistamines, cortisone, or similar drugs, must begin within minutes. Anaphylaxis may be caused by extremely small amounts of antigen
a life-threatening allergic reaction to a foreign antigen mediated by IgE antibodies Symptoms include swelling, shortness of breath and a decrease in blood pressure
(anaphylactic shock) a severe and life-threatening allergic reaction These rare reactions can occur following exposure to biological or chemical antigens such as microbes, insect stings, drugs, and even certain types of foods
Severe, life-threatening allergic response characterized by lowered blood pressure, swelling and hives
Anaphylaxis is the word used for serious and rapid allergic reactions usually involving more than one part of the body which, if severe enough, can kill
A severe allergic reaction that involves much of the body-the respiratory system, skin, digestive tract and, sometimes, blood circulation Symptoms include cough, wheezing, closing of the throat, runny nose, hives and swelling, nausea, vomiting, diarrhea, cramps and a drop in blood pressure that may cause loss of consciousness and even death
Severe allergic response to a substance Symptoms are wheezing, itching, hives, nasal congestion, intense burning of hands and feet, collapse, loss of consciousness, and cardiac arrest Symptoms appear within a few seconds or minutes after exposure Anaphylaxis is a severe medical emergency Without appropriate treatment, it can cause death Instructions for home treatment for anaphylaxis are under Emergency Guide For Anaphylaxis Victims"
hypersensitivity to substances following prior exposure, resulting in a severe allergic reaction
a sudden, severe, potentially life-threatening allergic reaction caused by food allergy, insect stings or medications Symptoms can include hives, swelling (especially of the lips and face), difficulty breathing (either because of swelling in the throat or an asthmatic reaction), vomiting, diarrhea, cramping and a fall in blood pressure
An immediate and severe allergic response; a shock reaction to a substance This can result in sudden severe breathing difficulty, severe drop in blood pressure, and/or loss of consciousness Anaphylactic shock can kill if not treated promptly Common causes of anaphylaxis include: bee stings in people that are allergic to bees, ingestion of certain foods by people that are allergic to those foods, and drug reactions
(Also called anaphylactic shock ) - a sudden, severe, potentially life-threatening allergic reaction caused by food allergy, insect stings, or medications Symptoms can include hives, swelling (especially of the lips and face), trouble breathing (either because of swelling in the throat or an asthmatic reaction), vomiting, diarrhea, cramping, and a drop in blood pressure
An extreme allergic reaction; an acute, generalized, and violent antigen-antibody reaction that can be rapidly fatal
