Treatment of Atopic Dermatitis in a Breastfeeding Woman
For this 25-year-old breastfeeding woman with atopic dermatitis affecting the antecubital fossae, axillae, and periareolar areas, initiate treatment with medium-potency topical corticosteroids applied twice daily to all affected areas combined with liberal emollient use, as both topical corticosteroids and calcineurin inhibitors are considered safe during lactation. 1, 2, 3
First-Line Topical Therapy
Start with medium-potency topical corticosteroids applied twice daily for 1-4 weeks to the antecubital fossae, axillae, and periareolar skin, as this represents the cornerstone of acute management per the 2023 American Academy of Dermatology guidelines 1, 4
Apply liberal amounts of emollients (alcohol-free moisturizers containing 5-10% urea) at least twice daily to all affected areas, immediately after bathing to restore skin barrier function 1, 5, 4
For the sensitive periareolar areas specifically, topical corticosteroids are safe during lactation and should be used to rapidly control symptoms, as nipple eczema can lead to premature cessation of breastfeeding if left untreated 3
Alternative for Sensitive Areas
Topical calcineurin inhibitors (tacrolimus 0.03-0.1% or pimecrolimus 1%) can be used as an alternative to corticosteroids, particularly for the face and intertriginous areas (axillae and periareolar skin), and are considered safe during lactation 1, 2, 3
The European Task Force on Atopic Dermatitis specifically endorses the safety of tacrolimus in breastfeeding women 2
Maintenance Therapy to Prevent Relapse
After achieving disease control, transition to proactive maintenance therapy with medium-potency topical corticosteroids applied twice weekly to previously affected areas for 16-20 weeks, which reduces relapse risk by 3.5-fold 1, 5, 4
Continue daily emollient use indefinitely as the foundation of long-term management 1, 5
Additional Supportive Measures
Avoid potential irritants in cleansers and moisturizers such as fragrances and preservatives 5
For the periareolar areas, warm water compresses or black tea compresses can provide additional comfort during acute flares 3
Advise intensive moisturization of the nipple and switching to emollient wash products if the periareolar involvement is affecting breastfeeding 3
When to Escalate Treatment
If topical therapy fails after 4 weeks of optimized treatment, consider phototherapy (narrowband UVB) as the next step, which is safe during lactation 1, 2
Systemic corticosteroids and cyclosporine A are the only systemic treatments deemed safe during lactation if severe disease requires escalation, though this should only be considered after topical therapy failure 2
Avoid systemic treatments such as dupilumab, JAK inhibitors, methotrexate, and azathioprine during breastfeeding due to insufficient safety data in this population 2, 6
Critical Pitfalls to Avoid
Do not discontinue topical therapy completely after resolution of acute flares, as this significantly increases relapse risk 5, 4
Do not rely on oral antihistamines as primary treatment for itch, as they are not effective for atopic dermatitis pruritus 5, 7
Do not use systemic antibiotics without clear evidence of secondary bacterial infection 5
Reassure the patient that topical corticosteroids and calcineurin inhibitors are safe during breastfeeding to ensure treatment adherence, as physician hesitancy often leads to undertreatment in this population 2, 3, 8
