Lay opinion often overestimates the power of IgE allergy training (allergen immunotherapy, AIT). Many believe it is a quick cure or that IgE levels alone predict success. Evidence shows a more nuanced picture. AIT is well-established for IgE-mediated allergies such as pollen, dust mite, and insect venom. It reduces symptoms, medication use, and improves quality of life, but requires 3–5 years of consistent treatment and does not work for everyone. Efficacy depends on allergen type, adherence, and comorbidities. Importantly, a positive IgE test alone is insufficient for diagnosis or treatment decisions; clinical history and, if needed, provocation tests are essential. For food allergies, evidence is weaker and AIT is not routinely recommended outside trials. Safety note: AIT carries a risk of anaphylaxis and must be administered by specialists. In summary, AIT is evidence-based but not a miracle. Lay people should seek specialist advice and maintain realistic expectations.
