From the Guidelines
Treatment of rosacea should prioritize topical metronidazole (0.75% or 1% gel or cream applied once or twice daily) as the first-line option, given its efficacy in reducing inflammatory lesions and perilesional erythema, as demonstrated in studies such as 1.
Overview of Treatment Options
Treatment options for rosacea include both topical and oral medications, as well as lifestyle modifications. Topical treatments are typically first-line and include:
- Metronidazole (0.75% or 1% gel or cream applied once or twice daily)
- Azelaic acid (15-20% applied twice daily)
- Ivermectin (1% cream applied once daily)
- Brimonidine (0.33% gel for temporary reduction of redness) For moderate to severe rosacea, oral antibiotics may be prescribed, particularly doxycycline (40-100mg daily for 8-12 weeks), which works primarily through anti-inflammatory rather than antimicrobial effects, as shown in 1.
Additional Considerations
For severe cases or those with ocular involvement, oral isotretinoin might be considered. Laser and intense pulsed light therapies can effectively reduce persistent redness and visible blood vessels. Lifestyle modifications are crucial and include avoiding triggers such as spicy foods, alcohol, extreme temperatures, sun exposure (using broad-spectrum SPF 30+ sunscreen daily), and using gentle, fragrance-free skincare products.
Individualized Treatment Approach
Treatment should be individualized based on rosacea subtype and severity, with most patients requiring long-term maintenance therapy after initial improvement. These treatments work by reducing inflammation, controlling skin microorganisms like Demodex mites, constricting blood vessels, or decreasing oil production depending on the specific medication, as discussed in 1, 1, and 1.
Recent Developments
Recent developments, such as the approval of microencapsulated benzoyl peroxide for rosacea, offer promising additions to the treatment landscape, as noted in 1. However, the primary approach remains focused on established treatments like metronidazole, given their proven track record and the emphasis on minimizing morbidity, mortality, and improving quality of life.
From the Research
Treatment Options for Rosacea
The treatment of rosacea involves a combination of self-help measures, topical medications, and systemic therapies. The goal of treatment is to control symptoms and prevent them from getting worse.
- Topical Medications: Topical agents such as brimonidine for erythema and ivermectin, metronidazole, or azelaic acid for inflammatory lesions are recommended as first-line choices for patients with erythematous and mild to severe papulopustular rosacea 2, 3, 4, 5.
- Systemic Therapies: Systemic antibiotics such as tetracyclines, and oral retinoids may be used to treat papulopustular rosacea, especially in cases where topical treatments are not effective 3, 4, 6.
- Light-Based Therapies: Light therapies such as intense pulsed light and pulsed dye laser may be used to treat the erythemato-telangiectatic type of rosacea 3, 6.
- Laser and Dermatosurgical Procedures: Laser and dermatosurgical procedures such as decortication may be used to treat rhinophyma, a condition characterized by thickening of the skin due to hyperplasia of sebaceous glands 6.
- Self-Help Measures: Avoidance of trigger factors, proper skin care, and photoprotection with wide-brimmed hats and broad-spectrum sunscreens are essential components of rosacea management 2, 4.
Treatment of Specific Subtypes of Rosacea
- Erythematotelangiectatic Rosacea: Topical brimonidine, azelaic acid, and metronidazole may be used to treat erythematotelangiectatic rosacea 3, 4, 5.
- Papulopustular Rosacea: Topical ivermectin, metronidazole, and azelaic acid, as well as systemic antibiotics such as doxycycline, may be used to treat papulopustular rosacea 3, 4, 5.
- Ocular Rosacea: Topical cyclosporine and oral or topical antibiotics may be used to treat ocular rosacea 4, 6.
- Phymatous Rosacea: Laser and light-based therapies, as well as dermatosurgical procedures, may be used to treat phymatous rosacea 3, 6.
