I never told my doctor about a past alle

Yes — tell them at the Thursday appointment, and if that past reaction involved breathing trouble, throat or tongue swelling, a hoarse voice, fainting, repeated vomiting, adrenaline, or an emergency visit, call the clinic before Thursday rather than waiting.

Why it matters
The point of the appointment is not to relitigate the old reaction — it is to get the history into your chart. Everything you tell them there is what the next prescriber, the pharmacist, the school office, and an emergency doctor will see. Leaving it out means every future decision is made on an incomplete record. This is a correction, not a confession; clinicians see this constantly and will not think less of you.

Say it in this shape (memorise it, don't read it)
"Before we start — I need to correct my record. On [date] I had an allergic reaction after [food/drug]. It started about [x] minutes later: [symptoms, in order]. It was worst at [x]. I [did nothing / took something / went to hospital]. It [did/didn't] come back. I've never been tested for it. I'd like that written into my chart, and I'd like to know whether I need an allergy referral, an adrenaline device and an action plan, and what to avoid."

Descriptive, not diagnostic. "This is what happened to me" — whether it was an allergy, an intolerance, or something else is theirs to work out, not yours.

Three questions to ask, and write them down before you go in

1. Do I need a referral to an allergy/immunology specialist, and how long is the wait?
2. Do I need an adrenaline auto-injector and a written action plan, and who fills it in and signs it?
3. Until I've been assessed, what should I avoid, and is any testing worth doing?

What to bring

• A one-page factual note: date, what was eaten or taken, how long to first symptom, symptoms in order, how long it lasted, what helped or what happened, whether it recurred, whether you were treated or hospitalised, and whether anything similar has happened since.
• The packaging, the ingredient list, or a photo of the label if you still have it.
• Any photo of the rash or swelling, if you have one.
• The name of anything you took for it (including anything bought without a prescription).
• A list of your current medicines and supplements.

What not to do

• Do not test it yourself again — don't eat the suspect food or take the suspect product "just to see". Whether it should be avoided, and whether testing is useful, is the clinician's decision.
• Do not change any current medication because of this conversation, and don't stop anything.
• Do not fill in the medication, dose, timing, or signature fields of an action plan yourself — those are the prescriber's to complete.
• Do not start immune supplements, detox powders, herbal remedies, or buy medication or devices online on the strength of this.
• Do not dose anyone else — including a child, an elder, or a pet — based on this episode.

Around the house until you've been seen

• Keep the suspected food out of shared meals for now, and tell anyone who cooks for your family.
• Wipe down shared surfaces and wash hands and utensils that handled it; label or store the suspect item separately.
• If there's a school or childcare angle, tell the office factually what happened and what you're waiting on. Don't ask them to administer anything.
• Keep the packaging in a bag, not the bin — it's evidence for a referral.

If a reaction is happening right now
Breathing difficulty, wheeze, throat tightness, swelling of the lips, tongue or throat, a hoarse or changed voice, paleness, weakness or collapse, altered consciousness, repeated vomiting, or rapid worsening: use their own prescribed auto-injector exactly as their plan and the device's leaflet say, have them lie down with legs raised (or sit up if breathing is difficult) and don't let them stand or walk, call your local emergency number, and arrange hospital assessment if adrenaline was used. Don't drive them yourself if they're deteriorating. I can't give you a number from memory — the emergency service in your area is the one to ring.

If that was a historical event only and nobody is unwell now
Then it is a routine item, not an emergency. Book it into the Thursday appointment, and bring the note. If the history included breathing, throat or tongue swelling, hoarse voice, fainting, repeated vomiting, adrenaline or emergency care, ring the clinic before Thursday and ask whether they want to see you sooner or have the record updated ahead of the visit.

20 minutes of prep, before Thursday

1. Fill in the factual note (10 minutes).
2. Photograph the packaging or put it in a bag by the door (2 minutes).
3. Write the three questions on your phone (3 minutes).
4. Tell the one other adult at home what's happening and what's on Thursday's list (5 minutes).

For the school, the pharmacy, or the other adult
"I had a reaction to [X] on [date]. It's not in my medical record yet — I'm correcting that with my doctor on [Thursday]. Until I've been assessed, I'm avoiding [X]. If a reaction happens, it will be treated with the plan my doctor gives me, and you'll see it in writing then."

What counts as success in 24 hours
Not a cure and not a label. Three things: an accurate one-page note, an honest conversation where you ask for the correction to be recorded, and a clear next step — referral, action plan, avoidance advice, or a plan for testing. If you leave with those three, the Thursday appointment did its job.

A note on the guidance behind this
This advice is consistent with published guidance in your region or a comparable one, but only your clinician applies your country's protocols. I relied on: ASCIA's Australian/NZ anaphylaxis and food-allergy guidance (including its advice that families document episodes and its event record), the Allergy Foundation of Australia (action plans updated when a new adrenaline device is prescribed or allergies change), BSACI's UK drug-allergy guidance (a new drug-allergy diagnosis should be updated in GP referral and hospital discharge records), and NICE's UK food-allergy quality statement on updating drug-allergy status. The archive copies I checked carried no publication or effective dates, so I can't tell you how current each text is, and I haven't verified any figure, wait time, or service number — any wait time your clinic quotes should be treated as an estimate until they confirm it.

One boundary worth stating plainly: I can't tell you what that reaction was, and I can't decide what belongs in your chart beyond describing what happened. That call belongs to the clinician in the room with you.
