Read oxycodone Results-at-a-Glance summary.

Oxycodone is a pain-relieving medicine often prescribed to mothers after giving birth. Studies have shown that oxycodone transfers into breastmilk, but data were lacking on how much of it is transferred to a breastfeeding infant. This information was needed for providers and mothers to make the best, safest decisions regarding medicines and breastfeeding. The Pediatric Trials Network (PTN) study called “Commonly Used Drugs During Lactation and Infant Exposure (CUDDLE)” tested medicines, including oxycodone, to learn how they transfer from mother to baby through breastmilk.
