Severe Allergic Reaction (Anaphylactic Shock) (cont.)

When to Seek Medical Care

Act quickly if someone experiences the symptoms of an anaphylactic reaction. True anaphylaxis is a medical emergency and requires immediate treatment in an emergency department of a hospital, where the person can be watched closely and life-saving treatment can be given.

  • It is impossible to predict how severe the allergic reaction will be. Any person who shows symptoms of anaphylaxis must be transported to a hospital emergency department.
  • If swelling develops rapidly, particularly involving the mouth or throat, and you have trouble breathing or feel dizzy, light-headed, or faint, call 911 for ambulance transport to the hospital.
  • While awaiting the ambulance, administer self-treatment.
