What might cause you to suspect a person is having an allergic reaction?

Several signs and symptoms may indicate that a person is having an allergic reaction. Here are some common signs to watch out for:

1. Skin:

- Hives or raised red bumps on the skin

- Swelling of the face, lips, tongue, or throat

- Itching or skin rash

2. Respiratory:

- Difficulty breathing or wheezing

- Shortness of breath or coughing

- Nasal congestion or a runny nose

- Hoarseness or a change in voice

3. Cardiovascular:

- Rapid heartbeat or palpitations

- Dizziness or lightheadedness

- Feeling faint or loss of consciousness

4. Gastrointestinal:

- Abdominal pain or cramping

- Nausea or vomiting

- Diarrhea

5. Other Symptoms:

- Itchy, watery eyes

- Sneezing or a stuffy nose

- Anaphylaxis, which is a severe, potentially life-threatening allergic reaction

If you suspect someone is having an allergic reaction, especially if they exhibit multiple symptoms or sudden and severe symptoms, it's important to take immediate action. Call emergency medical services (911 or your local emergency number) and provide assistance while waiting for help to arrive. If you or the person experiencing the reaction has an emergency epinephrine auto-injector (such as an EpiPen or Auvi-Q), it should be used as directed by a healthcare professional.
