Anaphylaxis, also called anaphylactic shock, is an acute, life-threatening allergic reaction. The reaction affects different organs in the body, one or several at a time. Even if the initial symptoms are experienced mildly, there is a risk that they may rapidly turn into a serious and severe condition. Anaphylaxis can occur immediately or within minutes, depending on the route of exposure, and can worsen quickly.
Common anaphylaxis symptoms can include:
- A sudden drop in blood pressure;
- Abdominal pain;
- Hives;
- Nausea and vomiting;
- Shortness of breath;
- Swelling around the eyes and the mouth;
- Tingling and itching around the mouth;
- Weak and rapid pulse.
