Atopic dermatitis (AD), commonly known as eczema, is a chronic, inflammatory skin condition that causes dry, itchy, and red skin. It's not contagious, but it can be a long-lasting and often frustrating condition to manage. Atopic dermatitis is part of a group of conditions known as the "atopic triad," which also includes asthma and allergic rhinitis (hay fever), and individuals often experience one or more of these conditions. This is because they share common genetic and immunological pathways.
The condition is believed to be caused by a combination of genetic and environmental factors. In many cases, it's related to a gene variation that affects the skin’s ability to act as a protective barrier. A weakened skin barrier makes it easier for moisture to escape and for irritants, allergens, and bacteria to enter, which can trigger an immune system response that leads to inflammation, redness, and itching.
Atopic dermatitis is a widespread health concern, affecting millions of people worldwide. It's particularly common in young children, with many cases beginning before the age of five, though it can persist into adulthood or even start later in life. The emotional and physical toll of the condition can be significant. The constant itching (pruritus) can lead to sleep disruption, which in turn can affect mood, concentration, and overall quality of life. The visible nature of the rash can also cause self-consciousness and social anxiety, especially in children and adolescents.
Beyond the physical symptoms, atopic dermatitis can lead to a cascade of related health issues. People with the condition have a higher risk of developing other atopic diseases like food allergies and asthma. They are also more susceptible to skin infections, as the compromised skin barrier allows bacteria like Staphylococcus aureus to thrive. A better understanding of AD can help individuals and their families recognize symptoms early, seek proper medical care, and develop effective management strategies, thereby improving their quality of life and preventing complications.
The landscape for atopic dermatitis treatment has evolved significantly, with new therapies and research offering hope for better symptom control and long-term management. Recent advancements have moved beyond traditional topical corticosteroids to include a new class of non-steroidal options and biologics.
Roflumilast Cream (Zoryve): Approved in 2024 for mild-to-moderate AD in adults and children aged 6 and older, this once-daily, non-steroidal cream is a phosphodiesterase 4 inhibitor that targets inflammation. In 2025, a lower-dose formulation was found to be safe for use in infants as young as 3 months, addressing a critical need for effective treatments in this age group.
Nemolizumab (Nemluvio): The FDA approved nemolizumab in December 2024 for patients 12 and older with moderate-to-severe AD. It is the first approved monoclonal antibody to specifically target the IL-31 receptor, a key player in the itch-inflammation cycle. This therapy represents a novel approach to addressing the intense itching that is a hallmark of the disease.
Lebrikizumab (Ebglyss): This targeted IL-13 inhibitor received FDA approval in September 2024 for adults and children 12 years and older with moderate-to-severe AD. Data presented at the 2025 American Academy of Dermatology (AAD) Annual Meeting demonstrated its long-term efficacy, showing that it can maintain skin clearance for up to three years with a once-monthly maintenance dose.
Probiotic Research: Ongoing research, including a study launched by the National Institute of Allergy and Infectious Diseases (NIAID) in 2025, is exploring the potential of using bacteria found on healthy skin as a topical therapy for eczema. A topical probiotic based on the bacterium Roseomonas mucosa became available in mid-2024, following NIAID-supported research that showed it can help restore the skin's natural lipids and reduce eczema symptoms.
While there are no specific, widespread laws dedicated solely to atopic dermatitis, a variety of regulations and government programs in the United States and other countries impact patients' access to care and treatment.
Insurance Coverage: The biggest factor for many patients is health insurance. Coverage for new and often expensive biologic therapies, as well as specialized prescription creams and ointments, is a major concern. Insurance companies often have specific criteria that must be met, such as trying and failing to respond to other treatments, before they will approve coverage for a particular medication. This can create significant barriers to accessing the most effective therapies.
Disability and Workplace Accommodations: Severe atopic dermatitis can be a qualifying condition for disability benefits if it significantly limits a person's ability to work. Additionally, federal laws in the U.S., such as the Americans with Disabilities Act (ADA), may require employers to provide reasonable accommodations for employees with chronic conditions like AD. This could include things like a modified work environment to avoid triggers, or access to special hand-washing stations and non-irritating soaps.
National Institutes of Health (NIH) Funding: Government agencies like the NIAID, which is part of the NIH, play a crucial role in funding research for atopic dermatitis. This research is vital for understanding the underlying causes of the disease and developing new, more effective treatments, as evidenced by the recent advances in probiotic therapies.
Managing atopic dermatitis often requires a multi-faceted approach, and a range of tools and resources are available to help patients and caregivers.
Patient Advocacy and Education Websites: Organizations like the National Eczema Association (NEA) and the Asthma and Allergy Foundation of America (AAFA) provide a wealth of reliable information. Their websites feature articles, webinars, and educational guides on understanding the condition, managing symptoms, and navigating treatment options.
Eczema Tracking Apps: Mobile apps can be powerful tools for monitoring symptoms and identifying triggers.
EczemaWise (by the NEA) is a free app that allows users to track their symptoms (itch, pain, sleep), potential triggers (diet, weather, stress), and treatments. It also helps users organize photos of their skin and generate reports to share with their doctor, facilitating more productive conversations.
Atopic App uses an AI model to analyze photos of the skin, assess the severity of eczema, and help users track the effectiveness of their treatment plan.
Online Support Groups and Communities: Connecting with others who have atopic dermatitis can provide a strong sense of community and help reduce feelings of isolation. Forums and social media groups, often moderated by organizations like the NEA, offer a safe space for people to share experiences, tips, and emotional support.

No, atopic dermatitis is not contagious. It is an inflammatory skin condition caused by a combination of genetics and environmental factors, not by a virus or bacteria that can be spread from person to person.
The "topic march" refers to the typical progression of allergic diseases in children. It often starts with atopic dermatitis in infancy, followed by the development of food allergies, and then progresses to allergic rhinitis and asthma later in childhood. Not everyone with AD will experience this progression, but it is a common pattern.
While food allergies can sometimes trigger an eczema flare-up, especially in infants, food is not the primary cause of atopic dermatitis. It's more often a response to irritants or allergens that come into contact with the skin. If you suspect a food allergy is contributing to your or your child's eczema, it's essential to consult with a doctor or allergist for proper testing and guidance, rather than eliminating foods on your own.
Atopic dermatitis is a chronic condition, meaning there is no definitive cure. However, with proper management, including a consistent skincare routine, trigger avoidance, and medical treatments, many people can effectively control their symptoms and have long periods of remission where the skin is clear. For some children, the condition may resolve entirely as they get older, but it can return later in life.
Atopic dermatitis is a chronic, often inherited, condition that is a result of a dysfunctional skin barrier and immune system. Contact dermatitis, on the other hand, is an allergic reaction to a specific substance that has come into direct contact with the skin, such as poison ivy, nickel, or certain soaps. While both cause skin inflammation, their underlying causes and treatment approaches differ.
