What is the best treatment approach for a patient with steroid-induced acne?

Steroid-Induced Acne Treatment

For steroid-induced acne, discontinue the causative corticosteroid if medically feasible, as this condition is self-limiting and typically resolves spontaneously without scarring once the steroid is withdrawn. 1

Key Distinguishing Features

Steroid-induced acne differs fundamentally from acne vulgaris in its clinical behavior and prognosis:

• Self-resolving nature: Steroid acne resolves on its own after drug withdrawal without scar formation, unlike acne vulgaris 1
• Monomorphic presentation: Typically presents with uniform papulopustular lesions rather than the mixed comedonal and inflammatory lesions of acne vulgaris 1
• Timing: Develops during or shortly after corticosteroid therapy (parenteral, oral, or high-potency topical) 1

Treatment Algorithm Based on Severity

Mild Steroid-Induced Acne

• Discontinue corticosteroid if clinically appropriate and observe for spontaneous resolution 1
• Apply topical benzoyl peroxide 2.5-5% daily for antimicrobial activity without resistance concerns 2
• Add topical adapalene 0.1% (available over-the-counter) if comedones are present 2, 3

Moderate Steroid-Induced Acne

• Discontinue or taper corticosteroid as medically feasible 1
• Use fixed-dose combination of adapalene + benzoyl peroxide as foundation therapy 2, 3
• Add topical clindamycin 1% combined with benzoyl peroxide for inflammatory lesions, never as monotherapy due to rapid resistance development 2, 3

Severe or Persistent Steroid-Induced Acne

• If unable to discontinue corticosteroid or if acne persists beyond 4-6 weeks after withdrawal, initiate oral doxycycline 100 mg daily plus topical retinoid plus benzoyl peroxide 2, 3
• Limit systemic antibiotics to 3-4 months maximum to minimize resistance 2, 3
• Always combine oral antibiotics with benzoyl peroxide to prevent bacterial resistance 2, 3

Special Consideration: Acne Fulminans Prevention

For patients on high-dose corticosteroids who develop severe inflammatory acne or systemic symptoms:

• Prednisone 0.5-1 mg/kg/day is indicated for acne fulminans or isotretinoin-induced acne fulminans-like eruptions 2
• Add oral isotretinoin at week 4, starting at 0.5 mg/kg/day, with slow corticosteroid taper over several months to minimize relapses 2, 4
• This combination produces faster control of systemic features and acne clearance compared to antibiotics or steroids alone 4

Critical Pitfalls to Avoid

• Never use topical or oral antibiotics as monotherapy—resistance develops rapidly without concurrent benzoyl peroxide 2, 3
• Do not extend oral antibiotics beyond 3-4 months without re-evaluation, as this dramatically increases resistance risk 2, 3
• Avoid treating steroid acne as standard acne vulgaris without first attempting corticosteroid withdrawal, as the condition is self-limiting 1
• Do not use long-term low-dose prednisone (5-15 mg daily) as primary acne therapy due to long-term adverse effects, despite its efficacy for acne and seborrhea 2

When Corticosteroid Cannot Be Discontinued

If the underlying medical condition requires continued corticosteroid therapy:

• Treat as moderate-to-severe acne vulgaris with triple therapy: oral doxycycline + topical retinoid + benzoyl peroxide 2, 3
• Consider isotretinoin if acne is treatment-resistant after 3-4 months, causes scarring, or produces significant psychosocial burden 2
• Standard isotretinoin dosing: 0.5-1.0 mg/kg/day targeting cumulative dose of 120-150 mg/kg 2, 3

Maintenance After Resolution

• Continue topical retinoid monotherapy indefinitely after achieving clearance to prevent recurrence 3, 5
• Benzoyl peroxide can be continued as maintenance therapy 3, 5
