Is Ketoprofen safe while breastfeeding?
Here is what NIH LactMed, the U.S. National Library of Medicine's authority on medicines and breastfeeding, reports about Ketoprofen. This is a summary of that source — not our own verdict.
Effects on the breastfed infant
All adverse reactions in breastfed infants reported in France between January 1985 and June 2011 were compiled by a French pharmacovigilance center. Of 174 reports, ketoprofen was reported to cause adverse reactions in 8 infants and to be one of the drugs most often suspected in serious adverse reactions, such as esophageal ulceration, erosive gastritis, meningeal hemorrhage, and renal insufficiency.[ 2 ]

Levels in milk
Maternal Levels . Eighteen women were given ketoprofen 100 mg every 12 hours (average 2.69 mg/kg daily) intravenously for 2 to 3 days postpartum. One to 4 milk samples were collected between the 3rd and 4th dose of ketoprofen. Of the 61 samples collected, ketoprofen was undetectable ( 20 mcg/L) in 17 of the samples. The authors assumed a milk concentration of 20 mcg/L for undetectable samples and calculated an average milk concentration of 57 mcg/L (range 20 to 177 mcg/L). A fully breastfed infant would receive an average dosage of 8.5 mcg/kg daily or 0.31% of the maternal weight-adjusted dosage.[ 1 ] Infant Levels .
