Allergy Emergency Card — Anaphylaxis & EpiPen Info Made Visible
An allergy emergency card lists the specific allergens that trigger anaphylaxis, what reaction to expect, the brand and dose of any epinephrine auto-injector you carry (EpiPen, Auvi-Q, Adrenaclick, generic 0.3mg/0.15mg), where on your body or bag you carry it, and at least two emergency contacts. The single most consequential field is the allergen name — generic “food allergies” tells a paramedic almost nothing useful.
Anaphylaxis can become fatal within minutes. The card's job is to compress the question “what is happening to this person and what should I do right now?” into something readable in 10 seconds.

What to put on a allergy emergency card
- •Specific allergens, named — “Peanut” and “tree nut” are different allergies and aren't cross-reactive in most patients. List each one. For drug allergies, write the drug class plus the reaction (e.g. “Penicillin — anaphylaxis 2019, hospital admission”). Common categories to be specific within: peanut, tree nuts (almond/cashew/walnut/etc.), milk, egg, soy, wheat, fish, shellfish (crustacean vs mollusk), sesame, latex, bee/wasp/hornet sting, specific drugs.
- •Reaction severity — Anaphylaxis vs hives vs delayed reaction matters for emergency decisions. “Peanut — anaphylaxis (throat swelling, low BP)” tells the paramedic to expect airway compromise. Distinguishing severe from mild prevents the card from being ignored when there's a real emergency.
- •EpiPen / Auvi-Q brand and dose — Brand (EpiPen, Auvi-Q, Adrenaclick, generic) and adult vs junior dose (0.3mg or 0.15mg). Brand matters because the activation steps differ — Auvi-Q has voice prompts; generic auto-injectors look slightly different from EpiPen. A bystander reading the card needs to know which device they're holding.
- •Where you carry the auto-injector — “EpiPen 0.3mg in left front pocket — give in outer thigh.” This single line saves the most time during a real reaction. The thigh-administration instruction matters because untrained bystanders default to upper-arm IM injections, which delivers the dose less reliably.
- •Co-existing asthma — Asthma plus food allergy is a known anaphylaxis risk multiplier — fatal cases are disproportionately concentrated in this group, per the AAAAI and other allergy bodies. List asthma if you have it; mention the rescue inhaler brand (albuterol/salbutamol).
- •Known cross-reactivities — Latex-fruit syndrome (latex + banana/avocado/kiwi), oral allergy syndrome (birch pollen + apple/peach), shellfish + iodine misconception (largely debunked but still relevant for ER staff). Listing “avoid contrast dye” or specific cross-reactions helps the team avoid an iatrogenic reaction during treatment.
- •Last reaction date and severity — A patient who hasn't had a reaction in 10 years is treated differently from one who anaphylaxed last month. ER staff use this to gauge how aggressive to be with epinephrine and observation duration.
- •Two emergency contacts — For children, list the parent or guardian first with relationship clearly stated. For adults, a spouse or close family member who knows the medical history. Both numbers should answer.
Why a allergy emergency card matters
Anaphylaxis is a time-critical emergency. Severe airway swelling, circulatory collapse, and respiratory arrest can develop within 5 to 30 minutes of exposure, and the only reliably effective treatment is intramuscular epinephrine — given fast. Delaying epinephrine in favour of antihistamines or steroids is the single most-cited factor in fatal anaphylaxis case reviews from the AAAAI and similar bodies.
The card's practical job is to remove the diagnostic delay. A bystander or first responder who finds someone struggling to breathe with hives and angioedema may not immediately recognize anaphylaxis — especially if the patient has had asthma exacerbations in the past and the symptoms overlap. A wallet card that says “Anaphylactic to peanuts — give EpiPen in left pocket, outer thigh, then call 911” compresses what would otherwise be a 10-minute history-taking exercise into a 10-second action plan.
For children, the card is also a delegated authority instrument. A teacher, camp counsellor, or babysitter who isn't medically trained still needs permission and instruction to inject epinephrine — and many adults hesitate without it. A laminated card pinned to the inside of a school bag, with a clear “use the EpiPen — do not wait” instruction, is part of the standard FARE-style emergency action plan for school-age kids.
For people with multiple allergies (especially those who have had a biphasic reaction, where symptoms return 4–12 hours after the initial episode), the card carries through the hospital admission too — ER staff will photograph it into the chart, and the second-phase treatment team has the same starting information.
In an emergency, call your local emergency number first — 911 (US/Canada), 999 (UK), 1122 (Pakistan), 112 (EU). This card is a supplement, not a substitute, for medical care.
