What is the treatment for acne rosacea?

Treatment of Acne Rosacea

For inflammatory papules and pustules, start with topical ivermectin 1% cream once daily as first-line therapy, as it demonstrates superior efficacy (84.9% achieving "clear" or "almost clear" ratings) and longer remission periods compared to other topical agents. 1

Treatment Algorithm by Disease Severity

Mild Rosacea (Inflammatory Papules/Pustules)

• Topical ivermectin 1% cream once daily is the preferred first-line agent based on superior efficacy and durability of response 1
• Alternative first-line options include:
  • Topical azelaic acid 15% gel/foam 1
  • Topical metronidazole 0.75% or 1.0% once daily (both strengths equally effective) 1
  • Encapsulated benzoyl peroxide 5% (shows rapid improvement by week 2 with sustained efficacy up to 52 weeks) 1

Moderate to Severe Rosacea

• Combination therapy is required: topical agent plus oral medication 1
• Recommended regimen: topical ivermectin 1% cream once daily + oral doxycycline 40mg modified-release daily 1
• The 40mg modified-release doxycycline formulation provides anti-inflammatory (not antibiotic) activity, reducing concerns about antibiotic resistance and gastrointestinal side effects 2
• Alternative oral option: minocycline foam 1.5% for moderate to severe inflammatory lesions 1

Persistent Facial Erythema

• Topical brimonidine tartrate 0.33% gel once daily provides rapid vasoconstriction with maximal effects between 3-6 hours after application 1
• Alternative: topical oxymetazoline HCl 1% cream once daily 1
• Important caveat: brimonidine causes paradoxical erythema in 10-20% of patients, so monitor closely 1

Telangiectasia

• Physical modalities are primary treatment: intense pulsed light (IPL) or pulsed-dye laser (PDL) 2
• Electrodessication is an option for severe cases 2

Phymatous Rosacea

• For clinically inflamed ("active") phyma: oral doxycycline or isotretinoin 2
• For clinically noninflamed ("fibrotic" or "burnt out") phyma: lasers or physical modalities 2

Ocular Rosacea

• Mild cases: lid hygiene and artificial tear substitutes 2
• Moderate to severe cases requiring more than lid hygiene: refer to ophthalmology and consider oral doxycycline 2, 1

Essential Adjunctive Measures (All Patients)

• Sun protection with SPF 30+ sunscreen 2, 1
• Gentle cleansers and moisturizers 2
• Trigger avoidance (spicy foods, alcohol, extreme temperatures) 1

Treatment Duration and Maintenance

Initial Treatment Phase

• Allow 3-4 weeks for improvement with most topical treatments 1
• Continue treatment for 6-12 weeks before considering it a failure (shorter for topicals, longer for oral agents) 2
• If first-line treatment fails, either switch to an alternative first-line option or add an additional first-line agent 2

Maintenance Therapy

• Long-term maintenance with topical agents is mandatory to prevent relapses 1
• Without maintenance therapy, up to two-thirds of patients will relapse when treatment is discontinued 1
• Use the minimum treatment necessary to maintain control 2, 1
• Topical ivermectin provides more durable response with longer time until relapse compared to metronidazole 1

Critical Clinical Pitfalls

Adherence Issues

• Up to 89% of patients who experience treatment-related adverse effects discontinue therapy within one month 1
• Counsel patients about expected timeline for improvement and potential side effects upfront 1

Combination Therapy Considerations

• Multiple cutaneous features can and should be treated simultaneously with more than one agent 2
• Moderate and severe presentations require combination treatments including pharmaceutical agents and potentially physical modalities 2

Paradoxical Reactions

• Monitor for paradoxical erythema with brimonidine (occurs in 10-20% of patients) 1
• If this occurs, discontinue brimonidine and consider oxymetazoline as alternative 1
