Living with Atopic Dermatitis (Eczema)

Understanding Atopic Dermatitis

Eczema, medically referred to as atopic dermatitis, is a chronic, inflammatory skin condition characterized by intensely itchy, red, dry, and cracked patches of skin. It is most common in infants and children, but it can persist into adulthood or even appear for the first time later in life. Eczema is not contagious; rather, it is related to a genetic variation that affects the skin's ability to retain moisture and provide a strong barrier against bacteria, irritants, and allergens.

The Eczema "Itch-Scratch" Cycle

One of the most defining and frustrating features of eczema is the severe itching (pruritus). The itching often precedes the rash, leading to a vicious "itch-scratch" cycle. Scratching the skin provides temporary relief but ultimately damages the skin barrier further, triggering more inflammation, increasing the risk of bacterial infection (like Staphylococcus aureus), and causing the skin to become thicker and more leathery over time (a process called lichenification).

Identifying and Managing Triggers

Eczema symptoms typically fluctuate, presenting as periodic "flare-ups" followed by periods of remission. Identifying what triggers these flare-ups is essential for long-term management. Common triggers include:

• Irritants: Harsh soaps, heavily fragranced detergents, bubble baths, wool or synthetic clothing, and certain cosmetic products.
• Environmental Factors: Extreme temperatures, low humidity (dry winter air), excessive sweating, and sudden changes in temperature.
• Allergens: Dust mites, pet dander, pollen, and mold. In some children, certain foods (like dairy, eggs, or nuts) can exacerbate symptoms.
• Stress: Emotional stress and anxiety are known to trigger inflammatory responses that can worsen eczema.

The Importance of Skin Hydration

The foundation of eczema management is aggressive, consistent skin hydration to rebuild the damaged skin barrier. Daily moisturizing is non-negotiable. Ointments (like petroleum jelly) and thick creams contain more oil than water and are highly effective at sealing in moisture. Lotions, which are mostly water, evaporate quickly and are generally insufficient for eczema-prone skin.

For the best results, apply moisturizers immediately after a short, lukewarm (not hot) bath or shower while the skin is still slightly damp. Avoid harsh scrubbing with towels; instead, gently pat the skin dry.

When to Seek Professional Treatment

When moisturizers and trigger avoidance aren't enough to control a flare-up, medical intervention is necessary to reduce inflammation and stop the itch. Topical corticosteroids are the standard first-line medical treatment.

At Ultima Pharmacy, our pharmacists are authorized to assess eczema flare-ups and prescribe appropriate topical treatments. Depending on the severity and location of the rash, we can prescribe low-to-moderate potency corticosteroid creams or ointments (such as hydrocortisone 1% or betamethasone valerate) to quickly bring the inflammation under control. We can also provide expert advice on the best medical-grade moisturizers and gentle cleansers to use daily.
