What products are safe on my skin while breastfeeding?
Most skin medications are compatible (poses little or no risk to the baby) with breastfeeding. Their ingredients show up only in small amounts in breast milk. However, some products that are used on the nipple and areola may be taken in by a breastfeeding baby and need extra scrutiny. For specific information, consult your health-care providers and other resources. Iodine-based antibacterial products used by mothers for skin and vaginal infections can affect a baby’s thyroid function. Most antifungal products are OK to use, although ketoconazole can affect a baby’s liver and should not be used on skin where the baby may eat it. Lindane, used to treat lice, should not be used by breastfeeding mothers, but most insect repellants, including DEET, are compatible with breastfeeding.
