Allergy Treatment Market Size, Trends and Growth Analysis by 2027

The global market for allergy treatments is projected to grow significantly, reaching approximately US$ 35,812.33 million by 2028, up from US$ 21,160.92 million in 2020. This growth represents a compound annual growth rate (CAGR) of 6.9% from 2020 to 2028.

Key factors contributing to the expansion of the global allergy treatment market include the rising adoption of immunotherapy and advancements in treatments for food allergies. Conversely, a lack of awareness regarding allergies and their management poses challenges to market growth.

Allergies are hypersensitive reactions of the immune system to substances that are typically harmless to most individuals. Common allergens include dust mites, animal dander, cockroach droppings, pollen, mold, certain foods, and various metal particles. While allergies can disrupt normal organ function, severe cases can be life-threatening; for instance, asthma can severely impair lung function. The most effective way to prevent allergic reactions is to avoid known allergens, although medications such as steroids and antihistamines are available for symptomatic relief.

Immunotherapy is available in two primary forms: allergy shots and sublingual immunotherapy (SLIT). Allergy shots involve administering increasing doses of allergen extracts, which are effective for allergies related to asthma, pets, dust, pollen, and stinging insects. SLIT, on the other hand, involves daily administration of tablets that dissolve under the tongue, making it a viable treatment option for nasal allergies and asthma. By repeatedly exposing patients to small amounts of allergens, immunotherapy helps reduce their sensitivity, alleviating allergic symptoms. This approach has demonstrated long-term benefits for patients and is suitable for self-administration in home care settings, establishing immunotherapy as a safe and effective alternative to traditional subcutaneous methods for managing chronic and recurrent allergies.

Research indicates that immunotherapy can reduce allergic symptoms by 60-65% in patients who complete their treatment regimen. A study published in the Annals of Allergy, Asthma and Immunology in February 2016 revealed that approximately 70% of allergy sufferers no longer require medication for their symptoms after undergoing immunotherapy. This treatment has proven effective for both children and the elderly, further driving the growth of the allergy treatment market.

Allergy Type Insights

The global allergy treatment market is categorized based on the type of allergy, including eye allergies, rhinitis, asthma, skin allergies, food allergies, and other types. In 2020, the rhinitis segment held the largest market share and is anticipated to maintain its leading position through 2028. The increasing prevalence of rhinitis, likely due to ongoing climatic and environmental changes, is driving demand for treatment options such as decongestants, antihistamines, and topical or oral steroids.

Treatment Insights

From a treatment perspective, the global allergy treatment market is divided into anti-allergy drugs and immunotherapy. The anti-allergy drugs segment accounted for a larger share of the market in 2020 and is expected to continue dominating through 2028. These medications are available in various forms, including tablets, nasal sprays, inhalers, liquids, ointments, injections, and eye drops.
