Anaphylaxis is an acute allergic reaction that affects the entire body. If you have ever experienced a life threatening allergic reaction to something, you remember how scared you were I am sure. Anaphylaxis is bad, an emergent condition that needs emergency care immediately or the person will die! Call 911! Emergency care providers are trained to care for these type of events. Driving yourself or your family member to the hospital yourself is not smart. You will delay care and possibly cause their death. Wait for EMS!
