We are in Austin, Texas, US.
About 15 minutes ago, my 5-year-old son (diagnosed peanut allergy, prescribed EpiPen Jr on hand) took one small bite of a friend's chocolate chip cookie.
His friend's mom checked the packaging, and the label says: "Manufactured in a facility that also processes peanuts; May contain peanuts and tree nuts."
ight now, he has no hives, no itching, lips and tongue look normal, voice is completely normal, and he is breathing easily.
I am terrified. Should I administer his EpiPen right now as a precaution, or do we wait and watch?
What exact warning signs mean I must inject the EpiPen and call emergency services, and how should he be positioned?
Answer
I'll read the allergy skill to give you the right guidance.
**Stay with him. Have the EpiPen Jr in your hand. Don't inject yet.**
He has no symptoms right now. With a "may contain peanuts" label and a known peanut allergy, this is "exposed, currently stable" — still treat as serious, but epinephrine is for actual anaphylaxis signs, not as a precaution. You're right to be terrified, and you're right that watching is the next step.
**Basis**
ASCIA and AAAAI: epinephrine is for trouble breathing, throat swelling, faintness, repeated vomiting, or two body systems reacting at once. Missing skin signs (no hives) does *not* rule out a reaction. Most food reactions start within 20 minutes; some can wait up to 2 hours. A biphasic second wave can come hours after the first one settles.
**Now**
- Have him lie flat on the floor, legs straight (or sit on the floor with legs out if breathing feels easier). No standing, no walking, no bathroom alone.
- Note the time of the bite; write down every change you see.
- Save the cookie wrapper — brand, lot, ingredients list.
- Have your local emergency number ready to dial.
- Don't give an antihistamine "to be safe" — it doesn't prevent or treat anaphylaxis and can mask early signs.
**Escalate — inject EpiPen Jr into the outer thigh, then call emergency, the moment you see any of these**
- Trouble breathing, wheezing, or noisy breath
- Hoarse voice or any change in how he sounds
- Throat tight or feels like it's closing
- Swelling of lips, tongue, or face
- Pale, floppy, blue lips or fingertips
- Sleepy, confused, or fainting
- epeated vomiting
- Hives plus another symptom (vomiting, cough, belly pain)
- Anything getting worse fast
**Limit**
We can't decide for you whether to ride this out at home or go straight to the E — that's your allergist's signed action plan. Even if he looks perfect for hours, biphasic reactions are possible, and many families go in for monitoring after a known-allergen exposure. If any sign above shows up: inject first, then call. When in doubt, inject — delay is more dangerous than a needless dose.
