Anaphylaxis is a life threatening response occurring within minutes of exposure to specific antigen and is manifested by respiratory distress due to laryngeal edema, intense bronchospasm, often followed by vascular collapse, shock, pruritus, uicaria with or without angioedema, and gastrointestinal manifestations in the form of nausea, vomiting, crampy abdominal pain, and diarrhea.
