One symptom of anaphylaxis is shock. When you’re in shock, the organs of your body don’t get enough blood, because your blood pressure is dangerously low. If the drop in BP is sudden and drastic, it can lead to unconsciousness, cardiac arrest, or death.
A person in shock may be pale or red, sweaty or dry, confused, anxious, or unconscious.
Their breathing may be labored or noisy, or they may be unable to breathe.
If you have severe allergies, you should keep two epinephrine injection kits with you and within easy reach at all times. If you feel like anaphylaxis may be happening, call 911 and use your epinephrine auto-injector right away, even if you’re not sure the symptoms are allergy-related.
