Ancef and Breastfeeding
Ancef (cefazolin) does pass through breast milk. However, the amounts of the drug that are passed through breast milk are so low that it is generally considered safe to breastfeed during Ancef treatment. Women who do nurse while receiving this antibiotic should be watchful for possible side effects in their child, such as thrush, nausea, or diarrhea.
Ancef® (cefazolin) passes through breast milk in humans. As with all cephalosporin antibiotics, while Ancef is usually considered compatible with breastfeeding, there are some precautions to consider. Therefore, if you are breastfeeding or plan to start, talk with your healthcare provider before using this drug.
Research has demonstrated that Ancef passes through breast milk in low amounts. This low amount appears to be safe for infants. However, it is possible that an infant who is exposed to Ancef through breast milk might be at risk for thrush or digestive upset, such as nausea or diarrhea. Mothers who receive Ancef while breastfeeding should be watchful for these potential problems.
In many situations, the potential risks are so small that it is not worth the hassle or the risk of potentially compromising the mother's breast milk supply to temporarily stop breastfeeding while using Ancef. The American Academy of Pediatrics considers the drug compatible with breastfeeding.
You should discuss breastfeeding and Ancef use 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.
