1. Understanding Allergy Immunotherapy: An Overview
Allergy immunotherapy aims to reduce sensitivity to allergens, offering long-term relief. Subcutaneous Immunotherapy (SCIT), commonly known as allergy shots, involves injecting small amounts of allergen extracts under the skin. Sublingual Immunotherapy (SLIT) is administered under the tongue, available in both tablet and drop forms. These therapies can help alleviate symptoms like sneezing, runny nose, and itchy eyes caused by allergens like grass pollen.
1.1 The Mechanism Behind Immunotherapy
Both SCIT and SLIT work by gradually exposing the body to increasing doses of allergens. This process helps the immune system build tolerance, reducing the severity of allergic reactions over time. The goal is to modify the immune response, shifting it away from an allergic reaction towards a state of tolerance. This ultimately leads to decreased symptom severity and reduced reliance on medication.
1.2 Types of Allergens Targeted by Immunotherapy
Immunotherapy can address a variety of allergens, including pollen (grass, tree, and ragweed), dust mites, pet dander, and mold spores. The specific allergens targeted depend on the individual’s allergy profile, determined through allergy testing. Different immunotherapy formulations are available to target single or multiple allergens. The selection of appropriate allergens is crucial for effective treatment.
1.3 The Importance of Accurate Diagnosis
Accurate diagnosis is essential before starting any form of immunotherapy. Allergy testing, such as skin prick tests or blood tests, identifies specific allergens triggering an allergic reaction. This information guides the selection of appropriate immunotherapy products. Self-diagnosis or relying on anecdotal evidence can lead to ineffective or even harmful treatments. Consultation with an allergist is crucial for accurate diagnosis and personalized treatment plans.
