Aspirin / oxycodone Pregnancy and Breastfeeding Warnings
Aspirin / oxycodone Pregnancy Warnings
Aspirin-oxycodone has not been formally assigned to pregnancy category by the FDA. Aspirin has been assigned to pregnancy category D by the FDA and oxycodone has been assigned to pregnancy category B by the FDA. Salicylates readily cross the placenta and inhibit prostaglandin synthesis, which may cause constriction of ductus arteriosus resulting in pulmonary hypertension and increased fetal mortality. Use of aspirin in pregnancy has been associated with alterations in both maternal and fetal hemostasis. Maternal aspirin use during later stages of pregnancy may cause low birth weight, increased incidence of intracranial hemorrhage in premature infants, stillbirths, and neonatal death. Use of aspirin during pregnancy, especially in the third trimester, should be avoided. Use of narcotic analgesics in late pregnancy has been associated with the risk of neonatal withdrawal. There are no controlled data in human pregnancy. Aspirin-oxycodone should only be given during pregnancy only when there are no alternatives and benefit outweighs risk.
Aspirin / oxycodone Breastfeeding Warnings
Aspirin is excreted into human milk in small amounts. Peak milk salicylate levels have been reported at nine hours after maternal dosing (and measured at 1.1 mg/dl). Because of a single case report of metabolic acidosis, the American Academy of Pediatric characterizes aspirin as a drug that has been "associated with significant effects on some nursing infants and should be given to nursing mothers with caution". Oxycodone is excreted into human milk, but the clinical significance is unknown.
