Anaphylaxis symptoms occur suddenly and can progress quickly. The early symptoms may be mild, such as a runny nose, a skin rash or a "strange feeling." These symptoms can quickly lead to more serious problems, including:
Trouble breathing
Hives or swelling
Tightness of the throat
Hoarse voice
Nausea
Vomiting
Abdominal pain
Diarrhea
Dizziness
Fainting
Low blood pressure
Rapid heart beat
Feeling of doom
Cardiac arrest
People who have had a severe allergic reaction are at risk for future reactions. Even if your first reaction is mild, future reactions might be more severe. That's why it's important to carry self-injectable epinephrine if you are at risk, and 911 should be dialed in the event of a very serious reaction.
Understanding anaphylaxis and the things that can trigger this severe allergic reaction will help you manage your condition.
