A 4-month-old infant has thrush while the mother is breastfeeding and reports nipple irritation. What is the best management?

• A. Have the mother exercise good hygiene of her nipples
• B. Administer an oral antifungal suspension to the mother
• C. Administer an oral antifungal suspension to the infant
• D. Treat the infant with an oral antifungal suspension and the mother's nipples with a topical antifungal agent

Answer: (D)

Candida infection in a breastfed infant often involves both the baby's mouth and the mother's nipples, and treating only one site allows the infection to persist or return. The best approach is to address both sources at the same time: give the infant an oral antifungal to clear thrush in the mouth, and apply a topical antifungal to the nipples to treat maternal candidiasis. This dual approach breaks the reinfection cycle between baby and mother and helps symptoms resolve for both. In practice, an oral antifungal such as an nystatin suspension is used for the infant, while the mother applies a topical antifungal (miconazole or clotrimazole) to the nipples after feeds for the duration of the treatment. Continuing to breastfeed is appropriate, and good hygiene—handwashing, cleaning bottles or pacifiers, and ensuring both mother and infant complete the full course—helps prevent recurrence. If thrush recurs or is persistent, reevaluation for possible resistance or consideration of alternative therapies may be needed.
