Allergy & Immunotherapy

About Allergen Avoidance

If you have been diagnosed with an allergic disorder e.g allergic rhinitis, reducing your exposure to environmental triggers has been shown, by many scientific studies,  to be partially effective as a means for prevention and treatment. [1]

The idea is straight forward: you first need to undergo allergy testing to evaluate your sensitivity to environmental triggers e.g. house dust mites. You then need to evaluate your environment (home, work, school) for the presence of those triggers. Once identified, an intervention is recommended that is targeted to reduce exposure to relevant triggers. When done correctly, this should, in principle, lead to reduction in severity and frequency of your symptoms.

While this approach sounds good in theory, in practice it is not easily achieved. Patients in the real world often face challenges when it comes to performing the necessary interventions.  [2] Nevertheless, this is an important component of allergy management and we strive to help our patients with strategies to minimise their exposure to common allergens.
