It is the most common type of rhinitis, which affects nearly 40% of the worldwide population. The most significant contributor to this is pollen. Pollens are generally transferred through air and, hence are incredibly light, making them easy to get carried by the wind. In addition, various studies have highlighted the impact of seasonal winds in increasing the pollen count in any region. Along with pollens, the other allergens contributing to the incidence of allergic rhinitis include dust mites, animal dander, and mold spores in the air.

Popular antihistamines such as Zyrtec and Allegra are available as tablets. They are also available as combination formulations with decongestants, such as tablets and syrups, for the pediatric population. In addition, corticosteroids are available as oral tablets, which can reduce inflammation all over the body through systemic action. Corticosteroids are therefore used to treat a variety of allergic illnesses, including allergic rhinitis, eczema, and pollen allergies.

In addition, retail pharmacies are most popular in growing economies such as developing countries. This is due to the need for more hospital pharmacies. Many big healthcare service providers also often acquire retail pharmacies, such as Apollo Pharmacy, to form their chain of retail pharmacies.

As the region rapidly develops in industrial development and urbanization, risk factors for allergies are also growing. In addition, various studies have highlighted that one of the leading reasons for allergies in adolescents and teenagers is the lack of exposure to allergens found in the environment when their immune system is under development, making adolescents more vulnerable to allergens. Such factors fuel the North American market growth.

Europe is anticipated to exhibit a CAGR of 7.60% over the forecast period. Europe is witnessing a rapidly increasing prevalence of allergies. It is believed that allergies affect more than 150 million people across the region, making it one of the most prevalent choric conditions. In addition, the European Academy of Allergy and Clinical Immunology (EAACI) has estimated that almost half of the European population will suffer from at least one form of allergy over the next 15 years. Europe has a prevalence of around 17% to 30% of allergic rhinitis. The incidence of allergic rhinitis is generally seen during childhood, progressing more severely during adulthood. In Europe, almost 45% of the population from the age group 20-45 years old shows the prevalence of allergic rhinitis. The prevalence is higher in western Europe, which is even higher, as the condition is highly underdiagnosed. Furthermore, one of the crucial factors for the growth of the allergy treatment market is the growing number of companies providing immunotherapies. This has increased investments in clinical research over the use of newer SLIT and OIT in allergy treatment.

Asia-Pacific is the fastest-growing market for allergy treatment products. It is home to many countries considered fast-paced economies or emerging markets, making it an ideal market for business expansion for companies in various sectors. Similar cases can be seen in the allergy treatment market, as growing awareness in the population over the severity of allergies and available treatment methods has caused the demand for treatment solutions to grow. In addition, many countries in Asia-Pacific are considered economically poor. People in such countries struggle to purchase epinephrine autoinjectors such as EpiPen, which are highly costly. Hence, the market in Asia-Pacific welcomes generic products more than branded ones, as they are more cost-effective. Allergies are one of the region's leading chronic and non-communicable diseases. Furthermore, the most significant risk factors in the region for allergies include demographic changes, smoking rates, drinking habits, pet adoption, lack of quality education, and family history of allergies.

Latin America includes three key countries as Brazil, Mexico, and Argentina. All three countries have an urbanization rate higher than 80%, with high air quality indices indicating higher air pollution. The region has a low awareness of allergic diseases, which has kept the diseases underdiagnosed. A similar approach is followed by physicians, who treat only symptoms of the diseases, with little to no focus on prevention, thereby hampering the market's growth.

The Middle East and Africa have specific types of allergies that are more prevalent in the Middle Eastern population than the other parts of the world. This is due to the differences in race, which change the susceptibility to specific allergies. Research has shown that the Middle Eastern population is more susceptible to dust mites. Along with this, food items such as cow milk, eggs, and peanuts are also sensitizing the population more rapidly than ever, boosting the market growth in the region.
