What is the treatment for facial rosacea?

Treatment of Facial Rosacea

Topical ivermectin 1% cream is the most effective first-line treatment for inflammatory papules and pustules of facial rosacea, showing superior efficacy and longer remission periods compared to other topical agents. 1

First-Line Treatments Based on Phenotype

For Inflammatory Papules/Pustules:

• Topical ivermectin 1% cream once daily is recommended as first-line therapy, with 84.9% of patients achieving "clear" or "almost clear" ratings compared to 75.4% with metronidazole 1
• Topical azelaic acid 15% gel/foam twice daily is an effective alternative, with improvement occurring in the majority of patients within four weeks 2, 3
• Topical metronidazole 0.75% or 1.0% (both strengths equally effective when used once daily) has been a mainstay therapy for decades 1, 4
• Encapsulated benzoyl peroxide 5% (E-BPO 5%) is the newest FDA-approved option (2022), showing rapid improvement by week 2 and sustained efficacy for up to 52 weeks 1

For Persistent Facial Erythema:

• Topical brimonidine tartrate 0.33% gel once daily provides rapid vasoconstriction (within 30 minutes) with maximal effects between 3-6 hours after application 1
• Topical oxymetazoline HCl 1% cream once daily is an alternative α1-receptor agonist for facial erythema 1

Treatment Algorithm Based on Severity

Mild Rosacea:

1. Start with: Topical ivermectin 1% cream once daily 1, 3
2. Alternative options:
   • Azelaic acid 15% gel/foam twice daily 2, 3
   • Metronidazole 0.75% or 1.0% once or twice daily 1, 4
   • E-BPO 5% cream once daily 1

Moderate to Severe Rosacea:

1. Combination therapy: Topical agent plus oral medication 3

   • Topical ivermectin 1% cream + oral doxycycline 40mg modified release daily 1, 3
   • Minocycline foam 1.5% is specifically recommended for moderate to severe inflammatory papules/pustules 3

2. For persistent erythema: Add topical vasoconstrictor 1

   • Brimonidine tartrate 0.33% gel once daily 1
   • Oxymetazoline HCl 1% cream once daily 1

Important Clinical Considerations

Treatment Duration and Maintenance:

• Improvement typically occurs within 3-4 weeks for most topical treatments 1
• Without maintenance therapy, up to two-thirds of patients will relapse when treatment is discontinued 1, 5
• Long-term maintenance with topical agents is recommended to prevent relapses 1, 5

Potential Adverse Effects:

• Temporary skin irritation (pruritus, burning, stinging) may occur with azelaic acid due to its low pH, especially at treatment initiation 2
• Brimonidine may cause paradoxical erythema in 10-20% of patients 1
• If irritation occurs with any topical agent, consider reducing application to once daily or temporarily discontinuing until symptoms subside 2

Special Considerations:

• Adherence to treatment is crucial - up to 89% of patients who experience treatment-related adverse effects discontinue therapy within a month 1
• E-BPO 5% demonstrated excellent tolerability and maintained a similar safety profile for up to 52 weeks 1
• Ivermectin 1% cream provides more durable response with longer time until relapse (115 days) compared to metronidazole (85 days) 1

Adjunctive Measures

• Sun protection (SPF 30+) is essential as UV exposure can trigger flares 3
• Use gentle cleansers and moisturizers to maintain skin barrier function 3
• Identify and avoid personal triggers (spicy foods, alcohol, extreme temperatures) 1
