Who is at risk for an anaphylactic attack?

Anyone can become a victim of anaphylaxis after they have been exposed once before to the allergen.  In other words, the first time a susceptible person eats peanuts or is stung by a stinging insect little or no reaction may result.  However, following the first exposure the body builds up a sensitization so that the next ingestion of peanuts or encounter with insect venom can result in a full-fledged anaphylactic attack.

Good to Know

People don’t always realize or remember they have had that initial exposure, so don’t automatically assume no reaction will occur.

Individuals who have had an anaphylactic reaction before are definitely at risk for another on the next exposure.  There’s no way to predict if it will be the same or more severe, so take it seriously and be on guard.
