Call 911 and get to the nearest emergency facility at the first sign of anaphylaxis, even if you have already administered epinephrine, the drug used to treat severe allergic reactions.

Delayed Anaphylaxis Delayed anaphylactic shock is a new idea in the world of allergies. Previously, it was assumed that anaphylaxis comes on within minutes of being exposed to an allergen, or not at all. Research carried out at University of Virginia has uncovered a severe delayed allergic reaction, which they call Delayed anaphylactic shock. It appears to be specific to a meat allergy: beef, pork or lamb. Anaphylaxis can occur 3 to 6 hours after eating these foods for those who are allergic to it. Symptoms can start with itching, progressing to hives on the skin’s outer and deeper layers. Swelling, intestinal irritation come next, along with airway constriction, chaotic heart beat and a rapid drop in blood pressure.
