Oxaprozin

Likely Compatibility

Fairly safe. Mild or unlikely adverse effects. Compatible under certain circumstances. Follow-up recommended. Read Commentary.

Oxaprozin is a nonsteroidal anti-inflammatory drug (NSAID), derived from propionic acid, used to treat osteoarthritis and rheumatoid arthritis. Oral administration once daily.

Since the last update we have not found published data on its excretion in breastmilk.

Its pharmacokinetic data (very high percentage of protein binding and wide volume of distribution) make it highly unlikely that significant quantities will pass into breast milk.

Until more published data is known about this drug in relation to breastfeeding, known safer alternatives are preferable, especially during the neonatal period and in the event of prematurity.

Alternatives

  • Diclofenac (Safe substance and/or breastfeeding is the best option.)
  • Ibuprofen (Safe substance and/or breastfeeding is the best option.)
  • Indomethacin; Indometacin (Safe substance and/or breastfeeding is the best option.)
  • Ketorolac Trometamol (Safe substance and/or breastfeeding is the best option.)
  • Piroxicam (Safe substance and/or breastfeeding is the best option.)

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
