From a case-series (resus council), fatal food reactions cause respiratory arrest typically after 30–35 minutes; insect stings cause collapse from shock after 10–15 minutes; and deaths caused by intravenous medication occur most commonly within five minutes. Anaphylaxis is the most severe form of an allergic reaction—it is rapid in onset and potentially fatal. Some people who are aware of their allergic reactions or allergens carry an emergency anaphylaxis kit that contains injectable epinephrine (a drug that stimulates the adrenal glands and increases the rate and force of the heartbeat).

Researchers typically distinguish between "true anaphylaxis" and "pseudo-anaphylaxis." Opioids can also have negative inotropic effects and induce a vagally-mediated bradycardia leading to hypotension – again, not a true allergic reaction… ... IgE mediated causes result in the true anaphylaxis which needs sensitizing at the first exposure and then on the second exposure they induce severe reactions. Death immediately occurs after the contact with the trigger if anaphylaxis is fatal, called anaphylactic shock. Visit Allergy Cosmos today to find out all you need to know about anaphylaxis.

Although extremely rare, anaphylaxis has been reported with some spices. Anaphylaxis is a severe allergic reaction. Researchers typically distinguish between "true anaphylaxis" and "pseudo-anaphylaxis or an anaphylactoid reaction." The symptoms, treatment, and risk of death are identical, but "true" anaphylaxis is always caused directly by degranulation of mast cells or basophils that is mediated by immunoglobulin E (IgE), and pseudo-anaphylaxis occurs due to all other causes. Read about how to treat anaphylaxis for more advice about using auto-injectors and correct positioning.

Hypotension can also occur due to arterial and venous vasodilation, thus, hypotension is more common in a volume depleted patient. Anaphylaxis and anaphylactic death are becoming more common and particularly affect children and young adults. [5] Lab based studies show that the allergenic ammonium groups on rocuronium are still able to interact with IgE antibodies when encapsulated by sugammadex.
