How do you manage steroid-induced acne if steroid use cannot be discontinued?

Management of Steroid-Induced Acne When Steroids Cannot Be Discontinued

For steroid-induced acne when steroids cannot be discontinued, the first-line treatment is a combination of topical antibiotics (such as clindamycin 2% or erythromycin 1%) with topical benzoyl peroxide, along with topical low/moderate strength corticosteroids for inflammation. 1

Assessment and Classification

When evaluating steroid-induced acne, consider:

• Distribution: Typically affects trunk, arms, and face
• Morphology: Monomorphic inflammatory papules and pustules
• Severity: Based on body surface area (BSA) affected and symptoms

Grading Scale:

• Grade 1: Papules/pustules covering <10% BSA
• Grade 2: Papules/pustules covering 10-30% BSA with symptoms
• Grade 3: Papules/pustules covering >30% BSA with significant symptoms

Treatment Algorithm

First-line Treatment (Grade 1-2)

• Continue steroid therapy as medically necessary
• Topical management:
  • Topical antibiotics: Clindamycin 2% or erythromycin 1% cream/lotion 1
  • Add benzoyl peroxide (2.5-5%) to prevent antibiotic resistance 2
  • Apply low/moderate potency topical steroid (e.g., hydrocortisone) for inflammation 1
  • Skin-type adjusted moisturizer 1

For Moderate to Severe Cases (Grade 2-3)

• Continue necessary systemic steroid therapy
• Add oral antibiotics for at least 2 weeks: 1
  • Doxycycline 100 mg twice daily OR
  • Minocycline 50-100 mg twice daily OR
  • Oxytetracycline 500 mg twice daily
• Consider topical retinoids if not contraindicated 1

For Severe or Refractory Cases

• Dermatology consultation 1
• Consider oral isotretinoin at low doses (20-30 mg/day) in consultation with dermatology 1
• For isolated inflammatory nodules: Intralesional triamcinolone acetonide (3.3-5 mg/mL) 1

Preventive Measures

• Avoid frequent washing with hot water 1
• Avoid skin irritants, over-the-counter anti-acne medications, and alcohol-based products 1
• Use alcohol-free moisturizers containing 5-10% urea twice daily 1
• Minimize sun exposure and use SPF 15+ sunscreen 1

Monitoring and Follow-up

• Reassess after 2 weeks of treatment 1
• If no improvement or worsening occurs, escalate to next level of treatment
• For patients on oral antibiotics, limit treatment duration to 6 weeks when possible to minimize resistance 1

Important Considerations

• Steroid-induced acne differs from acne vulgaris in that it typically resolves without scarring after withdrawal of the steroid 3
• When steroids cannot be discontinued, focus on controlling inflammation and preventing bacterial resistance
• Avoid using oral corticosteroids to treat steroid-induced acne as this may worsen the condition
• Consider split dosing of necessary systemic steroids if possible to reduce peak levels 4

Pitfalls to Avoid

• Don't mistake steroid acne for other dermatoses like rosacea or folliculitis
• Avoid long-term antibiotic use without benzoyl peroxide, as this increases risk of antibiotic resistance 2
• Don't use irritating topical products that can exacerbate inflammation
• Avoid abrupt discontinuation of systemic steroids if they're medically necessary

Remember that steroid-induced acne is a self-limiting condition that typically improves when steroid therapy is discontinued, but when steroids must be continued, a systematic approach focusing on topical therapies and targeted oral medications can effectively manage symptoms.
