Diphenhydramine Market Analysis

The diphenhydramine market is expected to record a CAGR of around 2.0% over the forecast period (2022-2027).

COVID-19 has an impact on many facets of social life, medical procedures, and allergy diagnosis and management. One of the most crucial forms of treatment for IgE-mediated allergies is allergen-specific immunotherapy (AIT), which is based on the diseased person's immunological responses. As a result, the market is expanding because of the rising prevalence of allergies caused by the outbreak. The report published by the University of Florida Health in 2022 under the title 'Two common compounds show effectiveness against COVID-19 virus in early testing' stated that a combination of diphenhydramine and lactoferrin, a protein found in cow and human milk, the combination compounds were found to block the SARS-CoV-2 virus during tests in monkey cells and human lung cells. Moreover, as per the report published in March 2022 under the title 'Antihistamines for Postacute Sequelae of SARS-CoV-2 Infection', histamine antagonists were linked to improved survival and slowed the onset of COVID-19 symptoms in critically ill individuals. These results are likely to cause the adoption of diphenhydramine during COVID-19. Thus, owing to the aforementioned factors COVID-19 had a significant impact on the diphenhydramine market.

An increased number of allergy cases and research and development initiatives in the fields of allergy are boosting the growth of the market. The 2020 update from the Centers for Disease Control and Prevention stated that depending on the allergen, allergic rhinitis symptoms may manifest only during seasons or all year round, affecting as many as 60 million Americans each year. As per the same source, pollen exposure can also trigger symptoms of allergic conjunctivitis. Allergic conjunctivitis is the inflammation of the lining of the eye (conjunctiva) due to exposure to allergens like those in pollen. Up to 30% of the general population and 7 out of 10 people with allergic rhinitis were likely to have allergic conjunctivitis in 2020.

Owing to the aforementioned factors diphenhydramine market is likely to grow over the forecast period. However, the side effect related to diphenhydramine restrains the market growth.

Diphenhydramine Market Trends

This section covers the major market trends shaping the Diphenhydramine Market according to our research experts:

Tablets Form is Estimated to Witness a Healthy Growth Over the Forecast Period.

COVID-19 had a notable impact on the diphenhydramine market. According to the Asthma and Allergy Foundation of America (AAFA), pollen allergies were less in 2020 as a result of COVID-19 restrictions. This was anticipated when many people spent more time indoors and were less exposed to pollen. Children were least affected by seasonal allergies because of fewer outdoor activities and closed schools. The travel limitations and lockdowns remained in effect throughout spring 2021, so there was less exposure to allergy particles. Hence, the COVID-19 pandemic had a significant impact on the tablet segment of the diphenhydramine market.

The tablets form segment is estimated to witness healthy growth in the future, owing to the wide availability of drugs, low cost of manufacturing, ease of administration, and convenience in storage. Tablets are durable, long-lasting, stable, and typically have a longer shelf life than capsules. A single tablet can accommodate a higher dose of an active ingredient than a single capsule. Increasing research and development in the field of allergy are boosting the market growth. For instance, according to Clinicaltrial.gov, there are more than 100 studies currently ongoing for diphenhydramine as of August 2022. With the increased pipeline study related to diphenhydramine and the other aforementioned reasons, the tablet segment is anticipated to increase the market growth over the study period.


North America is Expected to Hold a Significant Share in the Market and is Expected to do Same over the Forecast Period

North America is expected to hold a significant market share in the global diphenhydramine market, due to the increasing number of allergic populations. For instance, according to the 2022 report from the Asthma and Allergy Foundation of America, around 25 metropolitan areas are under the high-risk category for allergy attacks. Increased initiatives for providing awareness regarding allergy by the government are fueling the market growth. For instance, World Allergy Organization conducted world allergy week in 2022 from June 5th to 11th. The awareness week provides a need for greater attention and provides physicians and the public with a webinar, infographic, and additional information to educate and spread awareness on the allergy. As per the Asthma and Allergy Foundation of America (AAFA), Allergy Capitals Report March 2022, Scranton in Pennsylvania ranked 1 in the allergy population. As per the same source, more than 50 cities are on average at risk for allergy attacks. The same report emphasizes that there is a public health emergency since communities all over the country are experiencing the negative effects of climate change on their health in the United States. Some groups are even more vulnerable. Infants, kids, elders, expectant mothers, people of color, low-income groups, persons with disabilities, and many more who suffer from chronic illnesses like asthma are included in this. Thus, the increasing burden of allergic diseases is expected to aid the demand for diphenhydramine drugs and further propel the growth of the market in this region. Moreover, the increasing healthcare expenditure and the presence of well-established healthcare infrastructure are also fueling the growth of the overall regional market to a large extent.

According to the facts mentioned above diphenhydramine market is expected to grow in the studied region over the forecast period.
