Topical Corticosteroids for Atopic Dermatitis
For adults with atopic dermatitis, topical corticosteroids are strongly recommended as first-line treatment and should be selected based on potency class (I-VII), with the least potent preparation required to control symptoms being used. 1
Classification of Topical Corticosteroids
- Topical corticosteroids are grouped into 7 classes based on potency 1:
- Class I: Very high potency (e.g., clobetasol propionate 0.05%)
- Class II-III: High potency (e.g., fluticasone propionate 0.05%)
- Class IV-V: Medium potency (e.g., triamcinolone acetonide 0.1%)
- Class VI-VII: Low potency (e.g., hydrocortisone 1%)
Selection of Appropriate Topical Corticosteroid
Consider anatomical site when selecting potency 1:
- Lower potency agents should be used on face, neck, genitals, and body folds
- Medium to high potency can be used on trunk and extremities
- Very high potency should be limited to short courses due to risk of atrophy 1
Triamcinolone acetonide 0.1% cream is FDA-approved for inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses, including atopic dermatitis 2
Medium potency steroids can be utilized for longer courses due to more favorable adverse event profile 1
Application Guidelines
Most studies involve twice daily application, though once daily may be sufficient for potent topical corticosteroids 1
Treatment should not be applied more than twice daily 1
For maintenance therapy between flares, intermittent use of medium potency topical corticosteroids (twice weekly) is strongly recommended to reduce disease flares and relapse 1
A study showed patients treated with fluticasone propionate 0.05% cream for maintenance were 7.0 times less likely to have an AD relapse compared to vehicle (95% CI: 3.0-16.7; P < .001) 1
Potential Side Effects and Precautions
Main risk with potent topical corticosteroids is suppression of the pituitary-adrenal axis 1
Other potential side effects include skin atrophy, telangiectasias, and hypopigmentation, especially with prolonged use of higher potency steroids 3
Use the least potent preparation required to keep eczema under control, and when possible, corticosteroids should be stopped for short periods 1
"Corticophobia" (fear of using topical corticosteroids) can lead to undertreatment; proper education about benefits and risks is important 1, 3
Alternative and Adjunctive Treatments
For patients concerned about topical corticosteroid side effects, consider:
Emollients should be used in conjunction with topical corticosteroids and are most effective when applied after bathing 1
Antihistamines may be useful as short-term adjuvants during relapses with severe pruritus, primarily for their sedative properties 1
Common Pitfalls to Avoid
Undertreatment due to fear of topical corticosteroids 1
Using inappropriately high potency corticosteroids on sensitive areas like face, neck, and body folds 1
Failing to transition to maintenance therapy after controlling acute flares 1
Not considering alternative non-steroidal options for patients with steroid concerns or those who have failed topical corticosteroid therapy 3
