Symptoms of Anaphylaxis
Understand the symptoms so you can call 911 if you notice them.
What is Anaphylaxis?
Anaphylaxis (a-na-fi-LAX-is) is a life-threatening allergic reaction that can occur quickly (as fast as within a couple of minutes). Symptoms of anaphylaxis vary, but can include hives, itching, flushing, and swelling of the lips, tongue, and roof of the mouth. The airway is often affected, resulting in tightness of the throat, chest tightness and difficulty breathing.
“Allergies to food, insect stings, medications and latex are most frequently associated with anaphylaxis. Keep in mind that often a second anaphylactic reaction, known as a biphasic reaction, can occur as long as 12 hours after the initial reaction.”
These reactions can also be accompanied by chest pain, low blood pressure, dizziness and headaches. Anaphylaxis can be caused by a number of triggers, including but not limited to certain foods, stinging and biting insects, medications and latex.
Make sure you speak with your health care professional about how to identify the signs and symptoms of anaphylaxis.
Symptoms of anphylaxis may include:
- Trouble breathing
- Hoarseness (changes in the way your voice sounds)
- Hives (raised reddened rash that may itch)
- Severe itching
- Swelling of your face, lips, mouth, or tongue
- Skin rash, redness, or swelling
- Fast heartbeat
- Weak pulse
- Feeling very anxious
- Stomach pain
- Losing control of urine or bowel movements (incontinence)
- Dizziness, fainting, or “passing out” (unconsciousness)
Always call 911 in the event of a very serious reaction.
But, it is very important to understand the allergy and ensure you carry self-injectable epinephrine at all times if you or your family member are at risk.
