It is generally considered that diclofenac is a drug suitable for use by the mother during lactation, although the lack of a sufficient number of clinical studies makes it preferable to use other alternative medications (acetaminophen, ibuprofen). p>
No data on excretion of the drug in the milk or adverse effects have been reported on the infant, but it is recommended the replacement of diclofenac by any of the above when nursing a premature infant.
Warning of the manufacturer:
When administered gastro-resistant tablets every 8 hours (50 mg), can be found traces of the drug in breast milk, but in such small amounts that are not expected side effects in the baby. However, antiinflammatory drugs should be avoided if possible while breastfeeding.
