While technically you can take Percocet while breastfeeding, it’s highly recommended to avoid it if possible, especially if you're new to opioids. Percocet, which contains oxycodone, does transfer into breast milk and can potentially cause issues like sedation in your baby 1 . Some studies found oxycodone in breast milk up to 37 hours after taking the medication.
Here's the important bit: using doses over 30mg/day is generally discouraged in new-to-opioids breastfeeding moms. Higher doses could be considered in those who regularly took opioids during pregnancy, but it's really not the first choice.
So when it comes to Percocet and breastfeeding, the best advice is to consider other, safer alternatives for pain relief if available. Chat with your healthcare provider about the best course of action for you.
