Diflucan and Breastfeeding

There has been some controversy concerning Diflucan (fluconazole) and breastfeeding. While the manufacturer recommends that nursing mothers use this drug with caution, other sources suggest that Diflucan is harmless, since it can be used in infants -- even newborns -- directly. The American Academy of Pediatrics considers the medication to be safe when breastfeeding.

Is Diflucan Safe for Breastfeeding Women?

Diflucan® (fluconazole) passes through breast milk in humans. The manufacturer suggests that breastfeeding women should take this medication with caution. However, other sources suggest that Diflucan might be an acceptable choice during breastfeeding. Therefore, if you are breastfeeding, you should talk with your healthcare provider before taking this drug.

What Does the Research Say?

The manufacturer discourages the use of Diflucan while breastfeeding because the medication passes through breast milk in large amounts. However, it is important to understand that this medicine is used in infants directly and has been shown to be safe, even in newborns. In general, the American Academy of Pediatrics considers the drug compatible with breastfeeding.
For especially resistant thrush infections, Diflucan is sometimes prescribed to both a breastfeeding mother and an infant. Even though the medicine passes through breast milk in large amounts, the amount in breast milk is not enough by itself to treat thrush in the infant. The infant must also be treated directly.

Talking With Your Healthcare Provider About Breastfeeding and Diflucan

You should discuss Diflucan and breastfeeding with your healthcare provider. Each woman's situation is different, and you and your healthcare provider understand your situation best. After considering what you want and expect, as well as your current health situation, the two of you can make a shared decision that is right for you.
