A systemic response is caused by the release of immune and inflammatory mediators from basophils and mast cells. Allergy to food, medication, or venoms (including bites and stings) is the most frequent cause. Non-immunological anaphylaxis, previously described as an anaphylactoid reaction, produces similar symptoms. For more information: https://bestpractice.bmj.com/topics/en-gb/3000099
