Oxycodone is generally considered safe to use while breastfeeding, as only small amounts of the medication pass into breast milk. It is not typically considered toxic to the baby, especially if used occasionally or for a short period of time. It is recommended to monitor the baby for any signs of drowsiness, irritability, or constipation. It is also worth mentioning that a combination of Tylenol and Advil can be effective for dental pain, and oxycodone should only be used if needed for severe pain. It is okay to have a small supply of oxycodone on hand, but not necessary to use it if other options are effective.
