In the event of suspected anaphylaxis to food, which is a severe and potentially life-threatening allergic reaction, you must act quickly and seek emergency medical assistance immediately. If the individual has been prescribed an epinephrine auto-injector, it must be used immediately upon the onset of symptoms [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>). Following this, you must call emergency services even if symptoms improve, as medical monitoring at a hospital is necessary [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>).

## Anaphylaxis symptoms requiring immediate intervention

Anaphylaxis symptoms usually appear within minutes to two hours after consuming the offending food and can progress rapidly from mild to severe. Symptoms that require immediate medical intervention include:

- Severe shortness of breath due to swelling of the throat or blockage of the airways in the lungs [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>).

- A sharp drop in blood pressure and anaphylactic shock [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>).

- Loss of consciousness [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>).

- Sudden swelling of the lips, mouth, throat, or tongue [\[5\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S5>).

- Extreme difficulty breathing, with wheezing or a sensation of choking [\[5\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S5>).

- Skin, tongue, or lips turning blue, gray, or pale [\[5\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S5>).

- Sudden confusion, extreme drowsiness, or dizziness [\[5\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S5>).

Anaphylaxis may begin with milder symptoms such as hives, a skin rash, or a tingling sensation in the mouth, then escalate to become more dangerous [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>).

## Steps for handling suspected anaphylaxis

If you suspect that someone is suffering from food anaphylaxis, follow these steps:

1. **Use the epinephrine auto-injector:** If the person carries an epinephrine auto-injector (such as an EpiPen), administer it immediately according to the instructions [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>). It is essential that individuals for whom these injectors are prescribed learn how to use them and carry them at all times [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>).

2. **Call emergency services:** Call the local emergency number (such as 911 in the United States) immediately after using the epinephrine, or if an epinephrine injector is unavailable [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>).

3. **Stay with the person:** Do not leave the person alone until medical help arrives.

4. **Place the person in a comfortable position:** Help the person lie down or sit in a position that makes breathing easier for them.

5. **Monitor symptoms:** Pay attention to any changes in the person's condition and be prepared to provide accurate information to the paramedics.

## The importance of medical follow-up

Even if symptoms improve after using epinephrine, the person who experienced anaphylaxis must receive medical care at a hospital [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>). Observation in a medical facility for several hours is recommended even after the complete resolution of symptoms and signs [\[6\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S6>). It is also important to consult an allergy and immunology specialist after recovery to establish an allergy management plan and precisely identify triggers, which may include skin or blood tests [\[1\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S1>).

## Preventing future anaphylaxis

The only way to prevent allergic reactions to food is to avoid consuming the food that causes the allergy [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>). People with food allergies must read food labels carefully and avoid cross-contamination. A doctor may recommend wearing a medical alert bracelet or carrying a card that describes the allergy [\[4\]](<https://clinicsjo.com/en/faq/what-to-do-suspected-food-anaphylaxis#source-S4>).
