Recognising the symptoms of anaphylaxis and going into anaphylactic shock is very important for sufferers and carers. Watch this useful video to see how to recognise the symptoms and when you should administer an Adrenaline Auto-Injector epipen pen.

Just curious – are all reactions actually anaphylaxis of varying degrees or is there a substantial difference between the two?
Can you just get anaphylaxis even if you’ve never had it before and you have no known allergies?
or it something that comes on slowly over time so you are aware little by little – sorry two questions in one here x
Anaphylaxis is a type of allergic reaction, but all allergic reactions are not anaphylactic. Hives are an allergic reaction, or redness, or swelling, or just itching. Anaphylaxis is a serious allergic reaction where you lips, tounge, and airway swell… which can make it impossible to breathe.
I have a lot of allergies to EVERYTHING! I will literally pass by something, my hand will brush it, and i will break out with a rash on my hand. Does this increase my chances of developing anaphylaxis?
anaphalyxix is when u break out and then u go into shock stop breathing. it happens when you are overexposed. if u get rashes alot it wont increase or decrease ur chances
I suffer anaphylaxis requiring adrenaline injection. I have never used an injection but was told to carry one when I was stung by a bee when I was three. I didn’t have much of a reaction but allergies can change over time. Does this mean I am not eligible to join the British Air Corps? Can I get rid to the allergy?
my friend served 18 years in the US Navy with severe anaphylatic allergies to bee stings she served in dessert storm as far as getting rid of allergy go to medical doctor may be able to desensitize you however this does not work on ALL PEOPLE
need to know for biology assignment ,
i cant find the answer anywhere >.<
If you could get a person to a doctor or a hospital quickly enough then they could receive epinephrine from a doctor. That treatment has been around for a long time. The Epipen and similar autoinjectors have made it much simpler and faster to deliver the same treatment away from any medical resources.
Other than that, the only thing I can think of is that high doses of antihistamines might help, but also might take too long to work for them to be of any use.

Also, what would be the effects of administering an epi-pen? What effects would the excess adrenaline have on the person’s heart, lungs, etc?
"Overactive adrenal glands" generally produce excesses in steroids, usually the glucocorticoids, not epinephrine or norepinephrine. If you find somebody with pheochromocytoma and anaphylaxis, you have yourself a distinctly reportable case. That would make hens’ teeth look common.
Could it even be an anaphylaxis reaction if you don’t die in 2 hours? Leaving it untreated of course
Then you are probably okay, you would die before 2 hours I would think. Benadryl is probably the thing to take if anyone feels they are having that, as well as a trip to emergency asap.
Reading about wasps I was just wondering. I have a toddler, and it makes me think about anaphylaxis. If you are deathly allergic to something is it deadly the first time, or does it start off with a warning and get progressively worse?
If a person has a severe enough allergy to a substance (insect sting, food allergy, etc.) then it does NOT present the first time they are exposed to that allergen. The first time someone is exposed to an allergen, their body merely begins to build up the antibodies to that foreign substance. This can cause some allergic symptoms–such as hives, itching, or minor swelling–or may have no symptoms at all, but WILL NOT result in anaphylaxis until the second time that person is exposed. Upon the second exposure, the body recognizes the substance, and then and only then begins the extreme, all-body histamine reaction which results in anaphylactic shock. After that, anaphylaxis will occur every exposure thereafter (except for cases of pseudoanaphylaxis, but that is a rare occurrence which usually only come as a result to certain intravenous medications). Insect stings especially will often cause anaphylaxis as opposed to a less-severe allergic reaction, so if you toddler showed any signs of allergy upon being stung the first time, it might be a good idea to look into the matter, because it could be the warning reaction which occurs with a first-time exposure, and may be followed by a dangerous reaction if they are ever stung again. (with wasp stings, however, it is also possible that the toxins of the stinger could mimic the inflammation and redness of a possible warning-reaction, but it might still be a good idea to make certain there is no allergy if you are at all in doubt.)
I know adrenaline is used in treating anaphyalxis attacks. It relaxes the muscles and improves the blood pressures somehow. It also acts on the sympathetic pathway. But what is the exact mode of action in a biochemical level, which eventually leads to the recovery?
Epinephrine (also called adrenaline) is a natural hormone that your body makes to respond to stressful/ dangerous situations (basically it enables the fight or flight response). It makes your heart beat faster, opens your airways, diverts blood to your muscles, and constricts blood vessels. What the injection does is that it gives your body an extra boost of the hormone to stop the reaction (and it also has the added effect of reversing a reaction that swells your airways)
