Seasonal Allergic Rhinitis Market Size, Epidemiology, In-Market Drugs Sales, Pipeline Therapies, and Regional Outlook 2025-2035

Market Overview:

The seasonal allergic rhinitis market reached a value of USD 10.8 Billion across the top 7 markets (US, EU4, UK, and Japan) in 2024. Looking forward, IMARC Group expects the top 7 major markets to reach USD 14.7 Billion by 2035, exhibiting a growth rate (CAGR) of 2.87% during 2025-2035.

The seasonal allergic rhinitis market has been comprehensively analyzed in IMARC's new report titled "Seasonal Allergic Rhinitis Market Size, Epidemiology, In-Market Drugs Sales, Pipeline Therapies, and Regional Outlook 2025-2035". Seasonal allergic rhinitis, commonly called hay fever, refers to an allergic reaction that occurs in response to certain allergens present in the environment during specific seasons. It is characterized by inflammation of the nasal passages, resulting in various symptoms, such as sneezing, itching, a runny or stuffy nose, watery eyes, etc. Some individuals suffering from this ailment may also experience fatigue, coughing, sore throat, headache, nasal congestion, itchiness in the throat or ears, postnasal drip, impaired sleep cycle, etc. These symptoms can significantly impact daily activities and the overall quality of life. The diagnosis of seasonal allergic rhinitis is usually based on the patient's medical history, clinical signs, and physical examination. A healthcare provider may recommend skin prick tests to identify specific allergens that trigger the allergic reaction. Furthermore, radioallergosorbent testing is utilized to measure the amount of certain IgE antibodies in the blood that may be indicative of the disease. In some cases, a nasal provocation test is also required, which involves the introduction of a small amount of allergen directly into the nose to detect the cause of underlying symptoms.

The increasing cases of overactivation of the immune system, which results in the release of histamine and other chemicals, thereby leading to an allergic response, are primarily driving the seasonal allergic rhinitis market. Additionally, the rising incidences of exposure to pollen from grasses, trees, weeds, etc., which cause inflammation and irritation in the airways, are also creating a positive outlook for the market. Moreover, the widespread adoption of intranasal corticosteroids, including fluticasone, budesonide, mometasone, etc., to minimize the symptoms of the ailment is further bolstering the market growth. Apart from this, the escalating application of effective medications, like antihistamines, since they work by blocking the histamine receptors and reducing the swelling of blood vessels in the nasal passages to alleviate discomfort among patients, is acting as another significant growth-inducing factor. Additionally, the emerging popularity of allergy shots to treat this condition, owing to their several benefits, such as long-term relief, improved quality of life, and decreased need for other interventions, is expected to drive the seasonal allergic rhinitis market during the forecast period.

Recent Developments:

• In February 2025, Allergy Therapeutics released the publication of comprehensive data from its pivotal G306 Phase III trial of Grass MATA MPL, the Group's innovative subcutaneous immunotherapy (SCIT) candidate designed to address the cause of symptoms of allergic rhinoconjunctivitis due to grass pollen.

Drugs:

Qnasl (beclometasone dipropionate hydrofluoroalkane) is a corticosteroid nasal spray developed by Teva for seasonal allergic rhinitis. It works by delivering beclometasone directly to the nasal mucosa, where it inhibits inflammatory cytokines and mediators like histamines and leukotrienes. This reduces local swelling, nasal congestion, itching, and sneezing. Its hydrofluoroalkane propellant ensures fine mist delivery without chlorofluorocarbons, providing effective symptom control with minimal systemic absorption.

IRL-201104 is an under-development immunomodulatory drug by Revolo Biotherapeutics for the treatment of seasonal allergic rhinitis. This therapeutic compound is a peptide derived from mycobacterium tuberculosis chaperonin 60.1 that reduces neutrophil invasion into the lung, thereby decreasing inflammation. It is administered through intravenous and subcutaneous routes to reset the immune response with the potential for inducing long-term disease remission.

REGN5713-5714-5715 is an investigational molecule to treat seasonal allergic rhinitis. The therapeutic substance consists of three human monoclonal antibodies, including REGN5713, REGN5714, and REGN5715. It is delivered via intravenous and subcutaneous routes. The medicinal agent works by addressing the pollen allergen Bet v 1 in patients.
