Harmless things the immune system mistakes for a threat

An allergy is your immune system overreacting to something that's normally harmless. Better Health Channel's allergy overview lists grass pollen, peanuts, shellfish, pet dander, bee and ant venom, and some medicines among the usual culprits. Most reactions are a nuisance. Throat or tongue swelling, noisy breathing or collapse is anaphylaxis, and that means calling 000 straight away.

Tingling lips or an itchy mouth after one particular food

Swelling from a sting that spreads well past the spot

A rash you keep getting without knowing why

Reacting after starting a new medicine.

Where the reaction lands is the first clue to which allergy it is

Body location narrows things down quickly. Sneezing, an itchy nose and a constant drip at the back of the throat point to hay fever. Dry, itchy patches that flare in the creases of elbows and knees look more like eczema, which often turns up in families where hay fever and asthma run too.

Wheeze or a tight chest when pollen counts climb: asthma

Both eyes red, itchy and watering at the same time often means allergic conjunctivitis.

Food, sting and medicine reactions. These don't have their own page, so start with a GP consult.

Anaphylaxis needs an ambulance from the very first sign

Telehealth suits looking back at a past reaction and setting up testing. It can't help while a reaction is happening. ASCIA's anaphylaxis information says it should always be treated as a medical emergency.

Difficult or noisy breathing, or trouble talking, means an ambulance on 000.

Swollen tongue or a tight throat. Ring 000 at once.

Persistent dizziness or collapse, or a young child who goes pale and floppy: 000.

A puffy face or lips with no breathing trouble: get seen in person today, by a GP or at ED.

Finding your trigger is the main job of an allergy consult

History matters most. Your GP will ask what you ate, touched or were stung by, how quickly things started and what the reaction looked like, then decides whether skin prick or blood testing is worth doing. ASCIA's allergy testing advice warns that hair analysis, kinesiology and IgG food tests are unproven.

Referral to a clinical immunology or allergy specialist for skin prick testing or reactions that need more workup

Allergen-specific IgE blood tests via a pathology referral, if your doctor thinks they'll help

Running low on medicines you already take for allergies. Your GP checks they still suit you first.

Results and specialist letters shape the follow-up plan

Referrals and pathology forms arrive by email after the consult, ready to take to the lab or specialist. Once results are in, book a short follow-up so your GP can read them against your history. ASCIA Action Plans can only be completed by a treating doctor or nurse practitioner, and each one carries a review date worth putting in the calendar.

Keep the food label and a photo of the swelling

Reactions often fade before the call. A photo taken at the worst point, near a window in daylight, shows the GP far more than a description can.

Packaging or the ingredient list from what you ate

Roughly how many minutes passed between contact and the first symptom

Past allergy test results, or any action plan you already have.
