What are the symptoms of an anaphylactic reaction?
An anaphylactic reaction may begin with a tingling sensation, itching, or a metallic taste in the mouth. Other symptoms can include hives, a sensation of warmth, wheezing or other difficulty breathing, coughing, swelling of the mouth and throat area, vomiting, diarrhea, cramping, a drop in blood pressure, and loss of consciousness. These symptoms may begin within several minutes to two hours after exposure to the allergen, but life-threatening reactions may get worse over a period of several hours. In some reactions, the symptoms go away, only to return two to three hours later. This is called a “biphasic reaction.” Often these second-phase symptoms occur in the respiratory tract and may be more severe than the first-phase symptoms. Studies suggest that biphasic reactions occur in about 20 percent of anaphylactic reactions. See what happens inside the body during a food-allergic reaction.
