Also, they may develop very quickly — within seconds of exposure to an allergen — or evolve peopple an hour or so. An allergic reaction becomes more serious and is considered a medical emergency when any of the signs or symptoms are particularly severe, such as loss of consciousness or difficulty breathing, or if different parts or systems of the body are involved, such as having the combination of hives and vomiting, Dr. Sicherer says.

Anaphylaxis is a medical emergency. The patient may require resuscitation, including airway management, supplemental oxygen, intravenous fluids, and close monitoring. The person experiencing anaphylaxis will need an injection of adrenaline into the muscle.

Biphasic anaphylaxis is the recurrence of anaphylaxis within 72 hours with no further exposure to the allergen.
