Treatment of Atopic Dermatitis
For adults with atopic dermatitis, begin with topical corticosteroids and moisturizers as first-line therapy; for moderate-to-severe disease refractory to topicals, use dupilumab, tralokinumab, or JAK inhibitors (abrocitinib, baricitinib, upadacitinib) as these have the strongest evidence for efficacy and safety. 1
Stepwise Treatment Algorithm
Step 1: Foundation Therapy (All Patients)
- Apply moisturizers liberally and frequently to maintain skin barrier function 1
- Use soap-free cleansers with daily bathing 1, 2
- Implement trigger avoidance based on individual patient history 3
Step 2: First-Line Pharmacologic Treatment
Topical Corticosteroids (TCS):
- Primary treatment for active flares with potency selection based on body site 1, 2
- Continue maintenance therapy (1-2× weekly) on previously affected areas after stabilization to prevent flares 3
- Avoid prolonged use on face/sensitive areas due to atrophy risk 4
Topical Calcineurin Inhibitors (TCIs):
- Pimecrolimus 1% or tacrolimus are strongly recommended as first-line agents 1
- Preferred for facial/sensitive skin areas where corticosteroid atrophy is concerning 5, 4
- Pimecrolimus is FDA-approved as second-line therapy for patients ≥2 years who failed other topicals 5
- Tacrolimus shows superior efficacy compared to hydrocortisone 1% (56% vs 27% EASI score reduction) 6
Topical JAK Inhibitors and PDE-4 Inhibitors:
- Strongly recommended as first-line options 1
- Crisaborole (PDE-4 inhibitor) is effective but cost may limit use 2
Step 3: Second-Line Therapy for Refractory Disease
When topical therapy fails or disease significantly impacts quality of life:
Biologic Agents (Strong Recommendations):
- Dupilumab - strongest recommendation for moderate-to-severe AD 1
- Tralokinumab - strong recommendation 1
Oral JAK Inhibitors (Strong Recommendations):
Phototherapy (Conditional Recommendation):
- Narrowband UVB, broadband UVB, or UVA for extensive disease 1
- Safe and effective when first-line treatments inadequate 2
- Many patients require 1×/week maintenance indefinitely 1
Traditional Immunosuppressants (Conditional Recommendations):
- Cyclosporine (1-4 mg/kg/day): Effective for refractory AD; monitor creatinine (reduce dose if >25% above baseline) 1, 3
- Azathioprine (1-3 mg/kg/day): Dosing may be guided by TPMT enzyme activity 1
- Methotrexate (7.5-25 mg/week): Requires folate supplementation; monitor liver enzymes 1
- Mycophenolate mofetil: Variably effective alternative 1
Step 4: Adjunctive Therapies
During Active Flares:
For Secondary Bacterial Infection:
For Eczema Herpeticum:
Patient Education:
- Educational interventions and "eczema schools" are beneficial adjuncts 3
Critical Pitfalls to Avoid
Do NOT use:
- Systemic corticosteroids except for acute severe exacerbations as short-term bridge therapy only 1
- Oral antihistamines as routine treatment - insufficient evidence for efficacy; sedating antihistamines only for sleep loss from itch 1, 2
- Systemic antibiotics without documented infection 1, 3
- Dietary elimination based solely on allergy testing 3
- Probiotics, dietary supplements (fish oil, evening primrose oil, vitamins), or alternative therapies - lack evidence 3
Allergy Testing Guidance:
- Only perform when specific concerns identified in history 3
- Consider food allergy evaluation only in children <5 years with moderate-to-severe AD that persists despite optimized treatment or with reliable history of immediate reaction 3
- Patch testing for persistent/recalcitrant disease or suspected allergic contact dermatitis 3
