Death Anaphylaxis or Anaphylactic shock, is the most serious type of allergic reaction. It is the result of an antigen-antibody reaction that stimulates a massive secretion of histamine.

∙ 11y agoA severe allergic reaction can result in anaphylaxis with symptoms such as rashes/hives, swelling (particularly of the throat and tongue but also of the conjunctiva (the inner lining of the eyelids) and the lips) and decreased blood pressure and heart rate. It's a very fast reaction and can be brought on as a reaction to almost anything, including food (such as nuts), insect bites (such as bee stings) or certain medication (such as penicillin). If not treated immediately it can lead to death.
This type of reaction is very dangerous due to the rapid onset of very serious symptoms. The lowering of blood pressure means that less blood is getting around the body, leading to decreased oxygen availability to tissues and can lead to unconsciousness. Swelling of the throat is obviously very bad for breathing. Because of these problems, people with known extreme sensitivity to an allergen (an allergen being anything that triggers an allergic reaction) usually carry auto-injectors that will administer a shot of adrenaline (also called epinephrine) which will constrict blood vessels increasing blood pressure, stimulate the heart which increases heart rate, relax the smooth muscle of the throat and lungs to help with breathing, as well as reducing rashes/hives and any other areas of swelling. It's important that it auto-injects because if someone goes into anaphylaxis the combination of symptoms plus their instinct to panic means that they can administer the drug with ease.

Is a vasovagal reaction the result of an allergic reaction?
Allergic reactions are not typically a trigger for a vasovagal nerve reaction. However, there are a number of known triggers, as well as some unknown. Any type of nerve malfunction, stress, or pain can trigger a reaction, so the symptoms associated with an allergic reactions should not be ruled out entirely.
What defends the body from allergic reactions?
The simple answer is nothing. Allergic reactions are caused by your own immune system attacking itself. Since your immune system is your bodies defense against pathogens, and foreign objects an allergic reaction is a type of autoimmune disorder.
What type of reaction produces most of our energy?
Respiration, which is a redox reaction. C6H12O6 + 6O2 --> 6H2O + 6CO2
What type of reaction is dependent the most upon the concentration of the products or reactants?
reversible
In what kind of reaction can the products form the reactants?
The type reaction that changes the reactants into products is called a chemical reaction. Most chemical reactions can run forward or backward.
How do you treat allergic reaction to Percocet?
A doctor would treat an allergic reaction to Percocet by discontinuing the drug and ensuring that symptoms disappear, depending on the type of symptom. Most side effects are not serious, such as stomach discomfort, and pass quickly.
What does anaphylatic mean?
Comes from Anphylaxis, serious allergic reaction. Just specifies type of shock.
What is the most dangerous type of allergic reaction to food?
An extreme allergic reaction is called anaphylactic shock, and it is fatal if not treated very promptly with epinephrine.
Does an antigen cause an allergic reaction?
Only if the person is already allergic to that antigen. Not if they are immune to the antigen. The word antigen refers to the protein that joins with the antibody. If the antibody is of the allergic type (IgE) then an allergic reaction will happen and if the antibody is of the immune type (IgG, IgM or IgA) then there won't be an allergic reaction.
Can you get hives from penicillin?
Type your answer here... Yes you can get hives if you are allergic to penicillin. Usually, hives are what happens the first time a person displays an allergic reaction to penicillin. The next time a person takes penicillin, the reaction escalates past hives to a much more serious reaction involving difficulty breathing (airways restrict). A penicillin allergic reaction can cause death. People who are allergic to penicillin should wear a medical bracelet or necklace that clearly identifies their allergy.
What type of shock is an exaggerated allergic reaction?
Anaphylactic shock.
What type of antibodies initiates an allergic reaction?
IgE Group
