Yes, you can take naproxen while breastfeeding, but it's important to note that it does pass into breast milk. However, it's typically in such small amounts that it's unlikely to harm the baby. According to one study 1 , less than 1% of the mother's dose makes its way into breast milk. The concentration in breast milk is highest four to five hours after the medication is taken.
To minimize your baby's exposure, consider taking naproxen right after breastfeeding. This provides the longest period for the medication to be metabolized before the next feeding. But before taking naproxen, it's crucial to discuss it with your healthcare provider to ensure it's the right choice for both you and your little one.
