What should you know about pollen allergy anaphylaxis?

Seasonal pollen allergy commonly causes sneezing, a runny or blocked nose, itchy eyes and throat irritation. Anaphylaxis is different: swelling of the lips or tongue, a tight throat, wheezing, severe breathing difficulty, faintness, confusion or collapse can develop quickly. Skin changes such as widespread hives may occur, but they are not required.

Pollen is not a common trigger of anaphylaxis, yet a severe reaction should never be dismissed because it seems seasonal. Other exposures, including foods, medicines or insect stings, may be responsible.

If anaphylaxis is suspected, use the person’s prescribed adrenaline auto-injector immediately, call emergency services, and follow the dispatcher’s instructions. Keep the person lying down unless breathing is easier sitting; do not let them stand or walk. A second dose may be advised if symptoms persist and help has not arrived. Anaphylaxis Emergency Treatment explains emergency care, while Allergy Testing may help investigate triggers later.

Call emergency services immediately for breathing difficulty, wheezing, throat or tongue swelling, faintness or collapse after an exposure. Seek medical review for repeated seasonal reactions, uncertain triggers or symptoms that do not settle with the usual allergy plan. Wheezing needs assessment when it is new or severe.

Ask whether your symptoms fit seasonal allergy, asthma or anaphylaxis, whether you need an emergency action plan, and how to use an adrenaline device. Ask which triggers should be recorded and whether testing is appropriate.
