What are the management and medication options for atopic dermatitis?

Atopic Dermatitis Management and Medication

For atopic dermatitis, use daily moisturizers as the foundation, topical corticosteroids or calcineurin inhibitors for active inflammation, and maintain control with proactive twice-weekly application of these anti-inflammatory agents to previously affected areas after clearing—this stepwise approach prevents flares and optimizes long-term outcomes. 1

Foundation: Skin Barrier Restoration

• Apply moisturizers liberally immediately after bathing to hydrate skin and repair barrier dysfunction, with ceramide-containing formulations being particularly beneficial 2, 3
• Use gentle, soap-free cleansers to avoid removing natural lipids from the skin 2
• Daily bathing with emollients is recommended as primary therapy before escalating to pharmacologic treatments 1, 4

First-Line Pharmacologic Treatment

Topical Corticosteroids (TCS)

• Apply twice daily during active flares until improvement is seen, selecting potency based on anatomic location 2
• Choose lower potency for sensitive areas (face, intertriginous zones) and higher potency for thick skin or severe inflammation 1
• After disease stabilization, continue TCS 1-2 times per week to previously involved skin to prevent flares—this proactive maintenance approach is strongly recommended 1, 5

Topical Calcineurin Inhibitors (TCI)

• Consider as steroid-sparing agents, particularly for sensitive skin areas where potent TCS are potentially harmful 1, 2
• After disease stabilization, apply 2-3 times per week to previously affected areas to reduce subsequent relapses 1, 5
• Tacrolimus 0.1% for adults and 0.03% for children aged 2-15 years 6

Newer Topical Agents

• Topical JAK inhibitors and PDE-4 inhibitors receive strong recommendations for moderate-to-severe atopic dermatitis 1
• These agents provide additional options when traditional topicals are insufficient 1

Treatment Escalation for Inadequate Response

Phototherapy

• Recommended after failure of optimized topical regimens (emollients plus TCS/TCI used appropriately for 4-8 weeks) 1, 2
• Narrowband UVB is generally preferred due to favorable efficacy and safety profile 1, 3
• Multiple modalities are effective: NB-UVB, BB-UVB, UVA, and PUVA 1

Systemic Immunomodulators

Indicated when optimized topical therapy and/or phototherapy fail to control disease, or when significant psychosocial impact exists 1:

• Cyclosporine (1-4 mg/kg/day): Effective and recommended for refractory atopic dermatitis 1, 5
• Azathioprine: Recommended as systemic agent for refractory disease 1
• Methotrexate (7.5-25 mg/week): Recommended for refractory cases; folate supplementation is required 1
• Mycophenolate mofetil: May be considered as alternative therapy with variable effectiveness 1

Biologic Therapy

• Dupilumab (IL-4 receptor alpha antagonist) is FDA-approved for moderate-to-severe atopic dermatitis in patients aged 6 months and older whose disease is not adequately controlled with topical therapies 7
• Dosing for adults: 600 mg loading dose (two 300 mg injections), then 300 mg every 2 weeks 7
• Strong recommendation from American Academy of Dermatology for dupilumab and tralokinumab 3
• Particularly beneficial for patients with multiple atopic conditions (asthma, chronic rhinosinusitis) as it targets underlying Th2 inflammation 3

JAK Inhibitors (Systemic)

• Strong recommendations for abrocitinib, baricitinib, and upadacitinib for severe chronic atopic dermatitis 3, 8

Adjunctive Therapies

What TO Use:

• Educational interventions ("eczema schools", training programs) are strongly recommended as adjuncts to conventional therapy—these significantly improve outcomes 1, 5, 2
• Wet wrap therapy may be useful during acute flares 1
• Bleach baths (0.005% sodium hypochlorite) twice weekly for patients prone to skin infections 2, 8

What NOT to Use:

• Systemic antibiotics should ONLY be used when clinical evidence of bacterial infection exists—not for routine atopic dermatitis management 1, 5, 2
• Oral antihistamines are NOT recommended for primary itch control in atopic dermatitis, though may help with sleep disturbance 1, 2, 4
• Topical antimicrobials and antiseptics receive conditional recommendations against routine use 1
• Systemic corticosteroids should be avoided for long-term management; reserve exclusively for acute severe exacerbations as short-term bridge therapy 1, 3

Allergy Testing and Dietary Interventions

When to Test:

• Assess for environmental and food allergies during history taking—only pursue testing if specific concerns are identified (urticaria, immediate reactions) 1
• Allergy testing independent of clinical history is NOT recommended 1
• Patch testing should be considered in patients with persistent/recalcitrant disease or suspected allergic contact dermatitis 1, 5, 3

Food Allergy Evaluation:

• Children under 5 years with moderate-to-severe atopic dermatitis should be considered for food allergy evaluation (milk, egg, peanut, wheat, soy) ONLY if: 1, 5
  • Persistent disease despite optimized treatment, OR
  • Reliable history of immediate reaction after specific food ingestion
• Food elimination diets based solely on allergy test results are NOT recommended 1, 5, 3

Supplements NOT Recommended:

• No evidence supports probiotics/prebiotics, fish oils, evening primrose oil, borage oil, multivitamins, zinc, vitamin D, vitamin E, or vitamin B12/B6 1, 5

Common Pitfalls to Avoid

• Discontinuing topical anti-inflammatory therapy completely after flare resolution instead of transitioning to proactive maintenance (1-2x/week TCS or 2-3x/week TCI) 5, 2, 3
• Relying on antihistamines as primary treatment for itch rather than addressing underlying inflammation with appropriate anti-inflammatory therapy 5, 2, 3
• Using systemic antibiotics without documented infection—this does not improve atopic dermatitis outcomes 5, 2, 3
• Recommending elimination diets based solely on positive allergy tests without clinical correlation 5, 3
• Neglecting patient education—structured educational programs significantly improve treatment adherence and outcomes 5, 2
• Using products with fragrances and preservatives that may act as irritants 3

Treatment Algorithm Summary

1. Mild-to-moderate disease: Daily ceramide-containing moisturizers + TCS or TCI for active lesions + proactive maintenance therapy to previously affected areas 2, 3

2. Moderate-to-severe disease not responding to optimized topicals: Add phototherapy (preferably narrowband UVB) 1, 2, 3

3. Inadequate response to phototherapy or extensive disease: Initiate biologics (dupilumab or tralokinumab) or JAK inhibitors 3, 7

4. Alternative for severe refractory cases: Traditional immunosuppressants (cyclosporine, azathioprine, methotrexate, mycophenolate) with appropriate monitoring 1, 3
