Purpose of review Severe anaphylaxis is a generalized reaction in which cardiovascular and respiratory involvement lead to a fatal or near-fatal outcome. Triggers of severe anaphy- laxis differ from one age group to another and are mostly represented by drugs and hymenoptera stings in adults and food in children. Several risk factors and cofactors can increase the odds of severe anaphylaxis by different and still undefined mechanisms. Recent findings Major risk factors for severe anaphylaxis include old age, male sex, and preexisting medical conditions such as mast cell disorders, cardiovascular diseases, and uncontrolled asthma. Antihypertensive drugs appear to increase the severity of anaphy- laxis probably by impairing compensatory mechanism to support blood pressure during the reaction. Severe reactions are also associated with transient cofactors such as exercise following specific allergen exposure, treatment with nonsteroidal anti-inflammatory drugs, and alcohol consumption. Summary Identification of risk factors and potential concurrent cofactors for each indi- vidual patient is mandatory to prevent severe anaphylaxis. Risk stratification is crucial to develop personalized prevention strategies and action plans to avoid potentially life- threatening reactions.
