What Can I Take for a Yeast Infection While Breastfeeding?

A yeast infection, known as candidiasis or thrush, during the postpartum period can be a painful challenge for a breastfeeding mother. This fungal overgrowth, caused by Candida albicans, is easily passed between the mother and infant, leading to a cycle of reinfection. Selecting a treatment requires ensuring safety for the baby while effectively eradicating the infection for the mother. Understanding the infection’s presentations is the first step toward choosing the most appropriate treatment strategy while nursing.

Identifying Yeast Infections While Nursing

A yeast infection manifests in several ways in the breastfeeding dyad. For the mother, candidiasis often presents as nipple thrush. Symptoms typically include a sudden onset of intense nipple pain after comfortable feeding, often described as burning or itching. This discomfort can radiate deep into the breast tissue, feeling like shooting pain during or immediately after feeding. The nipples may appear bright pink, shiny, or flaky, and the pain is often disproportionate to the visual signs.

A mother might also experience a vaginal yeast infection, characterized by itching, burning, and thick, white discharge, which increases the risk of transmission to the breast. For the infant, oral thrush appears as white patches on the gums, tongue, or inner cheeks that cannot be easily wiped away. Both mother and baby must be accurately diagnosed by a healthcare provider, as nipple pain has other causes requiring different interventions.

Safe Topical Treatments for Mother and Infant

Topical antifungal medications are the preferred first-line treatment for both mother and baby due to minimal systemic absorption, making them safe for nursing. For the mother’s nipples, prescription or over-the-counter creams containing Miconazole or Clotrimazole are commonly recommended. These agents are applied in a thin layer to the nipple and areola after each feeding session, usually for ten to fourteen days. Applying the cream after nursing minimizes infant ingestion, and these topical agents do not need to be washed off before the next feed.

Simultaneously treating the infant is necessary to stop the cycle of reinfection, even if the baby appears asymptomatic. Infant treatment for oral thrush often involves Nystatin oral suspension, swabbed onto the baby’s mouth four times a day, or Miconazole oral gel for older infants. Nystatin works locally with very little absorbed systemically. Gentian Violet, a traditional antifungal dye, is another option applied once daily to the mother’s nipples and the baby’s mouth, though it is used cautiously due to staining and potential irritation. Successful treatment requires both mother and baby to complete the full course of medication.

Considerations for Oral Antifungal Medication

If topical treatments fail, or if the mother experiences deep, stabbing pain suggesting a ductal or internal breast infection, a systemic oral antifungal may be necessary. The most common medication prescribed is Fluconazole, which requires a prescription and medical supervision. Fluconazole treats Candida entrenched in the milk ducts, which topical agents cannot reach.

Fluconazole is acceptable during lactation because the amount passing into breast milk is less than the therapeutic dose given directly to an infant for thrush. A common regimen involves an initial loading dose of 400 milligrams, followed by 200 milligrams daily for at least two weeks, or until the pain resolves. The Fluconazole in breast milk is not sufficient to treat the baby’s oral thrush, meaning the infant still requires their own prescribed treatment, such as Nystatin suspension. Parents should monitor for rare, mild side effects in infants, such as upset stomach or diarrhea.

Managing Symptoms and Preventing Recurrence

Effective management relies on strict hygiene practices to eliminate fungal reservoirs. Candida thrives in warm, moist conditions, so maintaining dryness is paramount. This involves frequently changing breast pads, using ones without plastic liners, and allowing nipples to air-dry after each feeding. All items contacting the mother’s nipples or the baby’s mouth must be sterilized daily.

Sterilization Methods

  • Boiling pump parts, pacifiers, and bottle nipples for five to ten minutes.
  • Using a sanitizing steam bag.

Washing bras, towels, and clothing that touch the breasts in hot water with a vinegar rinse or bleach helps destroy yeast spores. Supporting the body’s natural defenses can also be helpful; some mothers reduce the intake of simple sugars and refined carbohydrates or add a probiotic supplement to restore beneficial bacteria.
