Immediate Steps: Toddler Allergic Reaction What to Do

1. Stay Calm
   • Speak in a soothing voice to reassure your child.
   • Panic can worsen your toddler's distress.

2. Remove the Allergen
   • Take away any food, insect or substance causing the reaction.
   • If it's food, wipe your child's hands and face to avoid more exposure.

3. Assess Severity
   • Check breathing, skin color and level of alertness.
   • Look for signs of anaphylaxis listed above.

4. Give Antihistamine for Mild Reactions (if prescribed)
   • Only use a doctor-recommended dose.
   • Liquid diphenhydramine or cetirizine may help itching and hives.

5. Administer Epinephrine Auto-Injector for Severe Reactions
   • If your child has a prescribed epinephrine (EpiPen® or generic), inject immediately into the outer thigh.
   • After injection, massage the area for 10 seconds.
   • Always carry two auto-injectors in case a second dose is needed.

6. Call Emergency Services (911 in the US)
   • If you've used epinephrine
   • If you see any severe symptoms developing
   • Do not wait to see if symptoms improve

7. Position Your Toddler
   • If breathing is difficult, have them sit up slightly.
   • If they feel faint or dizzy, lay them flat and elevate their legs (unless they're vomiting).

Administering Epinephrine: Step by Step

• Remove the safety cap.
• Hold the auto-injector at a 90° angle to the outer thigh.
• Press firmly until you hear a click.
• Hold for 3–10 seconds (follow device instructions).
• Call 911 immediately, even if your child seems better.
• Note the time of injection to inform paramedics.

After the Injection and While Waiting for Help

• Monitor breathing and consciousness continuously.
• Keep your toddler warm and comfortable.
• Do not give any other medications unless instructed by medical professionals.
• Inform emergency responders about all medications given and time of injection.

Why Emergency Care Matters

Even if your child seems to recover after epinephrine, symptoms can return (biphasic reaction) 4–12 hours later. Emergency staff will:

• Observe vital signs (heart rate, breathing)
• Provide oxygen or IV fluids if needed
• Give additional medications (steroids, antihistamines)
• Monitor for delayed symptoms

Follow-Up Care and Prevention

1. Speak with Your Pediatrician or an Allergist
   • Discuss allergy testing (skin or blood tests) to identify triggers.
   • Develop a personalized Allergy Action Plan.

2. Stock and Maintain Medications
   • Keep two epinephrine auto-injectors at home, daycare and with caregivers.
   • Check expiration dates monthly.

3. Educate Family and Caregivers
   • Teach siblings, grandparents and babysitters how to spot a reaction and use the auto-injector.
   • Provide everyone with a copy of the Allergy Action Plan.

4. Label and Avoid Triggers
   • Read food labels carefully for hidden allergens.
   • When eating out, inform restaurant staff of your toddler's allergy.
   • Wash hands and surfaces to prevent cross-contact.

5. Consider Medical ID and Emergency Cards
   • A medical ID bracelet or necklace can alert first responders.
   • Carry a wallet card with allergy details and emergency instructions.

6. Practice Emergency Drills
