About Anaphylaxis (severe allergic reaction)
A severe allergic reaction that occurs rapidly and causes a life-threatening response involving the whole body. This reaction can lead to difficulty breathing and shock, ultimately leading to death.

Initial contact with the allergen may not produce any symptoms.
