Allergic Rhinitis Drugs Market

Allergic Rhinitis Drugs Market Size

The global allergic rhinitis drugs market size was valued at USD 13.7 billion in 2024 and is estimated to grow at a CAGR of 3.9% from 2025 to 2034. The market for allergic rhinitis drugs is growing due to the increasing prevalence of allergic rhinitis in children and adults.

The market is driven by factors such as climate change, pollution, and urbanization. According to the Asthma and Allergy Foundation of America, over 81 million people in America suffered from seasonal allergic rhinitis in 2021. The market is also growing due to increased awareness and better access to healthcare services.

The market is witnessing growth due to the introduction of combination therapies, such as antihistamine and corticosteroid sprays, which can manage multiple symptoms at the same time. Other forms of immunotherapy include sublingual (SLIT) and subcutaneous (SCIT) therapies. These treatments provide lasting relief for patients with ongoing allergic rhinitis, which helps expand the market scope. According to the American Academy of Allergy, Asthma & Immunology, these types of immunotherapies can help up to 85% of patients suffering from allergic rhinitis. The development of biologic therapies for patients with severe, hard-to-treat allergic rhinitis is expected to further drive market growth.

Allergic rhinitis is an inflammation of the nasal cavities triggered by certain allergens, which is treated using anti-allergic medications known as allergic rhinitis drugs. These medicines help reduce symptoms like sneezing, nasal congestion, itching, and inflammation of the eyes that occur when the body reacts to allergens such as pet hair, dust, or pollen. The most commonly used drugs for allergic rhinitis are antihistamines, intranasal corticosteroids, and immunotherapy.

Allergic Rhinitis Drugs Market Trends

Increasing prevalence of allergic rhinitis is a key trend driving the growth of the market.
