Table 1: Risk Factors For the Development of Anaphylaxis

Table 1:
Risk Factors For the Development of Anaphylaxis
Risk Factor	Comment
Age	Children: higher frequency of food-related anaphylaxis Adults: higher frequency of anaphylaxis related to antibiotics, radiocontrast media, anesthetic agents, and insect stings
Gender	Females: anaphylaxis to latex, aspirin, radiocontrast media, and muscle relaxants more frequent Males: anaphylaxis to insect venom more frequent
Socioeconomic status	Increased frequency of anaphylaxis with higher socioeconomic status
Route of administration	Oral antigens less likely to trigger anaphylaxis than parenteral antigens. Oral antigens less likely to trigger severe symptoms than parenteral antigens
Timing of administration	Interrupted therapy more likely to predispose to anaphylaxis
Atopy	Risk factor for both anaphylactic and anaphylactoid reactions
Exposure history	The longer the interval since previous antigen exposure, the less likely a reaction will occur
