Treatment for a Breastfeeding Mother When Her Baby Has Thrush

When a baby has oral thrush, both the mother and baby should be treated simultaneously with antifungal medication to prevent reinfection, even if the mother is asymptomatic. 1

Treatment Options for the Mother

First-line Treatment

  • Topical antifungal treatment should be applied to the nipples/areola after each feeding:
    • Nystatin cream 1
    • Clotrimazole gel 2
    • Miconazole cream 3

For Persistent or Severe Cases

  • Oral fluconazole is recommended for mothers with persistent symptoms or severe cases that don't respond to topical treatment 1, 4:
    • Loading dose: 200 mg on first day
    • Maintenance: 100-200 mg daily for 14-30 days (duration depends on symptom resolution) 4

Important Considerations for Fluconazole Use

  • Fluconazole is present in breast milk at approximately 13% of the maternal dose, but this is considered safe for the infant 5
  • Breastfeeding can continue during fluconazole treatment 5
  • Other azole antifungals (besides fluconazole) are not recommended during breastfeeding 3

Signs and Symptoms of Candidal Mastitis in the Mother

  • Burning, stinging pain that radiates from nipples into the breast 4
  • Pain that persists throughout and after feedings 4
  • Cracked nipples that don't heal despite proper latch 4
  • Absence of classic mastitis symptoms (fever, redness) 3
  • Symptoms may fluctuate between topical (surface) and ductal (deeper) infection 6

Treatment for the Baby

  • Oral nystatin suspension (100,000 units/mL): 1 mL four times daily for 7-14 days 3, 1
  • Alternative: Fluconazole oral suspension 3 mg/kg once daily for 7 days (shown to be more effective than nystatin in infants) 7

Important Clinical Pearls

  • Treat both mother and baby simultaneously, even if one appears asymptomatic, to prevent reinfection 6, 2
  • Continue treatment for at least 7-14 days, even if symptoms resolve earlier 3
  • Persistent cases may require longer treatment courses (up to 6 weeks in some cases) 4
  • Pain management may be necessary for the mother to continue breastfeeding during treatment 4
  • Keep the affected areas dry between feedings 3
  • Sanitize pacifiers, bottle nipples, and toys that go in baby's mouth 1

Common Pitfalls

  • Treating only the baby and not the mother can lead to persistent reinfection 2
  • Discontinuing treatment too early when symptoms begin to improve 4
  • Failing to recognize candidal infection when white plaques aren't visible in the infant's mouth (some cases present without visible plaques) 6
  • Inadequate duration of treatment leading to recurrence 1
  • Not considering candidiasis in mothers with persistent nipple pain, especially following antibiotic treatment 4

By treating both mother and baby simultaneously with appropriate antifungal medications for an adequate duration, the candidal infection can be effectively resolved, allowing for continued successful breastfeeding.
