Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for some types of allergies. It is useful for environmental allergies, allergies to insect bites, and asthma. Its benefit for food allergies is unclear and thus not recommended. Immunotherapy involves exposing people to larger and larger amounts of allergen in an attempt to change the immune system's response. The primary therapeutic goals of allergy immunotherapy (AIT) include reducing symptoms, reducing symptomatic medication use, and improving allergyrelated quality of life. The evidence is strong that AIT achieves these goals and can alter the course of the disease, with benefits persisting in many patients for several years after treatment discontinuation.
The global allergy immunotherapy market is primarily driven by the rising prevalence of allergic conditions, such as allergic rhinitis, asthma, and food allergies, which affect hundreds of millions of individuals worldwide. Growing awareness about long-term treatment options and the effectiveness of immunotherapy in providing sustained symptom relief is increasing its adoption. Additionally, advancements in diagnostic techniques, improved formulations such as sublingual tablets, and support from regulatory authorities have facilitated market growth. The increasing demand for personalized medicine and a shift toward disease-modifying therapies are further propelling the market forward.
Despite its therapeutic potential, the allergy immunotherapy market faces several challenges. The long treatment duration—often lasting three to five years—can lead to poor patient compliance and high dropout rates. High upfront costs and limited reimbursement in some regions restrict accessibility for many patients. Moreover, the requirement for specialized healthcare infrastructure and trained professionals, especially for subcutaneous immunotherapy, limits adoption in low-resource settings. Safety concerns, including the risk of systemic allergic reactions, also hinder broader acceptance, particularly among pediatric and elderly populations. These barriers collectively slow market penetration and limit the therapy’s full potential.
