What are the recommended therapies for rosacea in breastfeeding patients?

Rosacea Treatment During Breastfeeding

For breastfeeding patients with rosacea, topical azelaic acid 15% gel/foam or topical metronidazole 0.75-1% are the safest first-line options, as these agents have minimal systemic absorption and are considered compatible with lactation. 1, 2

Treatment Algorithm by Severity

Mild Inflammatory Rosacea (Papules/Pustules)

• Start with topical azelaic acid 15% gel or foam once to twice daily 1, 3

  • Azelaic acid has less than 4% systemic absorption, making uptake into maternal milk negligible 2
  • The FDA label specifically states that while passage into milk may occur via equilibrium dialysis studies, the low systemic absorption means no significant change from baseline azelaic acid levels in milk is expected 2
  • Expect improvement within 4-6 weeks 1

• Alternative: Topical metronidazole 0.75% or 1% once to twice daily 1, 3

  • Both strengths are equally effective when used once daily 3
  • Produces up to 65% decrease in inflammatory lesion counts 1
  • Improvement typically occurs within 3-4 weeks 3

• Consider topical ivermectin 1% cream once daily for superior efficacy 1, 3

  • Shows 84.9% of patients achieving "clear" or "almost clear" ratings versus 75.4% with metronidazole 1, 3
  • Provides longer time to relapse (115 days) compared to metronidazole (85 days) 1
  • However, safety data in breastfeeding is more limited compared to azelaic acid and metronidazole

Moderate to Severe Inflammatory Rosacea

• Avoid oral doxycycline during breastfeeding 4

  • The FDA explicitly contraindicates doxycycline in nursing women 4
  • This applies to both standard antimicrobial doses and the 40mg modified-release anti-inflammatory formulation

• Use combination topical therapy instead: 1

  • Apply azelaic acid 15% gel in the morning and ivermectin 1% cream in the evening to minimize irritation 1
  • This combination approach can provide additive benefits without systemic medication 1

Persistent Facial Erythema

• Topical brimonidine 0.33% gel once daily 1, 3

  • Provides rapid vasoconstriction with maximal effects between 3-6 hours after application 3
  • Caution: May cause paradoxical erythema in 10-20% of patients 3

• Alternative: Topical oxymetazoline HCl 1% cream once daily 5, 1

  • Composite success rate of 12.3-14.8% at 12 hours versus 6.0-6.1% with vehicle 5
  • No tachyphylaxis reported with long-term use up to 52 weeks 5

Important Clinical Considerations

Application Guidelines

• When using multiple topical agents, separate application times (one morning, one evening) to minimize potential irritation 1
• Temporary skin irritation (pruritus, burning, stinging) may occur with azelaic acid when applied to broken or inflamed skin, usually at treatment start 2
• If irritation persists, apply azelaic acid only once daily until effects subside 2

Maintenance Therapy

• Continue topical therapy long-term to prevent relapse 3
  • Without maintenance, up to two-thirds of patients relapse when treatment is discontinued 3
  • Topical metronidazole maintenance decreases relapses and allows longer intervals between flares 6

Common Pitfalls to Avoid

• Do not use oral tetracyclines (doxycycline, minocycline) while breastfeeding 4

  • These are contraindicated in nursing mothers due to potential effects on infant bone and tooth development 4

• Avoid topical corticosteroids on the face 7

  • Can cause steroid rosacea as a complication 7

• Do not discontinue treatment prematurely 3

  • Up to 89% of patients who experience treatment-related adverse effects discontinue therapy within a month, leading to poor outcomes 3
  • Allow at least 8 weeks before considering treatment failure 4

Adjunctive Measures

• Implement trigger avoidance and gentle skincare 3
  • Use sun protection with SPF 30+ 3
  • Apply gentle cleansers and moisturizers 3
  • Identify and avoid personal triggers such as spicy foods, alcohol, and extreme temperatures 3
