High Risk for breastfeeding

Poorly safe. Evaluate carefully.
Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives).

Very often used for treatment of pain associated to episiotomy or Cesarean section operation.

Excreted and accumulates into breast milk in significant amount along with associated problems among 20% of breastfed infants from treated mothers. Side effects have been rarely severe like excessive sedation, letargia, hypothermia and apnea. Dose should not be higher than 30 mg a day for no longer than 3 days.

Women with some variants of enzyme-linked gene CYP2D6 who are on Oxycodone and their breastfed infants may experience increased sedation. Dose should not be higher than 30 mg a day for no longer than 3 days.

Use of Oxycodone during childhood is risky because of a large elimination half-life variability.

Adequately use of nonsteroidal anti-inflammatory drugs (NSAIDs) may attain pain relief with less side effects than with narcotic analgesics.
