Anaphylaxis from pollen

Sneezing, a runny or blocked nose, and itchy or watery eyes fit the usual pattern of airborne pollen allergy. Pollen exposure can also worsen asthma, causing cough, chest tightness or wheezing. Anaphylaxis is a different, whole-body emergency and may present with throat or tongue swelling, breathing difficulty, widespread hives, repeated vomiting, dizziness or collapse. Wheezing deserves prompt attention, especially if it is severe, worsening, or occurs with throat, skin, digestive or circulation symptoms.

Give prescribed epinephrine immediately when the person’s symptoms and emergency plan indicate anaphylaxis, then call emergency services. Do not delay epinephrine while trying antihistamines or an asthma reliever; an inhaler may help bronchospasm but does not treat throat swelling or low blood pressure. Position the person flat with legs raised if tolerated, or supported upright if breathing is difficult. If unconscious but breathing, place them on their side. Prevent walking, and follow their plan for another prescribed dose if symptoms remain severe or come back.

Seek emergency help for throat tightness, tongue swelling, laboured or noisy breathing, a hoarse voice, faintness, confusion, collapse or rapidly progressing symptoms across different body systems. Severe wheezing that limits speaking or does not respond to the person’s prescribed asthma plan also needs urgent help. Assessment is required after epinephrine even if the person feels better, because symptoms may recur. Start CPR if they become unresponsive and stop breathing normally, if you are able.

Bring a clear account of where the exposure occurred, the symptom order, any foods or medicines involved, and how treatment affected the reaction. This helps distinguish pollen-triggered nasal allergy or asthma from anaphylaxis and from another trigger. Ask whether allergy testing would clarify your triggers, how pollen and asthma plans should work together, and whether you should carry epinephrine. Confirm device technique, medicine storage in heat and the warning signs written into your personal action plan.
