Rosacea Treatment
Treat rosacea using a phenotype-based approach that targets specific presenting features rather than traditional subtypes, with first-line topical agents for mild disease and combination therapy for moderate-to-severe presentations. 1
Treatment Algorithm by Phenotype
Inflammatory Papules/Pustules
Mild Disease:
- Start with topical ivermectin 1% cream as the preferred first-line agent 2, 3
- Alternative first-line options include azelaic acid 15% gel/foam or the newly FDA-approved encapsulated benzoyl peroxide 5% (E-BPO 5%), which shows rapid improvement by week 2 2, 3
- Topical metronidazole is also effective but demonstrates inferior efficacy compared to ivermectin (73.7% vs 83% lesion reduction at 16 weeks) 3
Moderate-to-Severe Disease:
- Use combination therapy with oral doxycycline 40 mg modified-release daily PLUS a topical agent (ivermectin or azelaic acid) 2, 3
- The 40 mg modified-release formulation provides anti-inflammatory activity without antibiotic effects, reducing gastrointestinal side effects and antibiotic resistance concerns 2, 3
- For severe refractory disease, consider oral isotretinoin, which demonstrates 91% clearance or excellent response even at very low doses 2
Persistent Erythema
- First-line treatment is topical brimonidine (α-adrenergic agonist) 2
- Alternative option is topical oxymetazoline 2
- Oral beta blockers such as carvedilol may be considered, though evidence is limited 2
Transient Erythema/Flushing
- Topical α-adrenergics are first-line 2
- Oral beta blockers or pulsed-dye laser are alternative options 2
Telangiectasia
- Laser or light-based therapies (intense pulsed light, pulsed dye laser) are the primary treatment modalities 4, 5
Phymatous Changes
- Laser or light-based therapies are the primary treatment 5
- Oral isotretinoin may be considered for severe cases 2
Essential Adjunctive Measures (All Patients)
- Sun protection: Daily broad-spectrum SPF 30+ sunscreen 2, 3
- Gentle skincare: Use mild, non-medicated cleansers and moisturizers to support skin barrier function 2, 3
- Trigger avoidance: Identify and avoid individual triggers including spicy foods, alcohol, extreme temperatures, though RCT evidence for this approach is limited 2, 3
Treatment Duration and Response Assessment
- Allow 6-8 weeks for topical agents before declaring treatment failure 2
- Allow 8-12 weeks for oral agents before declaring treatment failure 2
- If first-line treatment fails after adequate duration, either switch to an alternative first-line agent OR add an additional first-line agent 1, 3
Combination Therapy Approach
Multiple cutaneous features should be treated simultaneously with multiple agents, as moderate and severe presentations typically require combination treatments (topical plus systemic or multiple topicals). 2, 3
Maintenance Therapy
- Without maintenance therapy, up to two-thirds of patients relapse when treatment is discontinued 2, 3
- Continue the minimum treatment necessary to maintain remission 2, 3
- Topical agents alone may suffice for maintenance after initial combination therapy 3
- Long-term doxycycline 40 mg has demonstrated safety for extended use 3
Ocular Rosacea Management
- Mild symptoms: Lid hygiene and artificial tears 1, 2
- Moderate-to-severe symptoms: Oral doxycycline 40 mg modified-release 2
- Ophthalmological referral should be considered for all but the mildest ocular features 1, 2
Critical Pitfalls to Avoid
- Do not treat based on traditional rosacea subtypes—this approach fails to address the full spectrum of presenting features and may lead to inadequate management 1, 3
- Do not use traditional non-encapsulated benzoyl peroxide formulations—only E-BPO 5% is FDA-approved for rosacea with reduced irritation 3
- Do not extrapolate acne treatment protocols to rosacea—rosacea represents fundamentally different pathophysiology 2
- Do not discontinue treatment prematurely—insufficient treatment duration leads to false treatment failures 2
- Counsel patients about photosensitivity with doxycycline and its contraindication in pregnancy, nursing, and children under 8 years 3
- Do not overlook ocular manifestations—ocular rosacea is frequently underdiagnosed and undertreated 2
