Answer by Dr. Ru: About Mefenamic Acid usage in lactation

Excretion into breast milk is non-significant without side-effects reported in breastfed infants from treated mothers. It was not found, or, only in very low levels neither in the plasma nor the urine of those infants. Because of a paucity of published reports on it, it is recommended the use of alternative medication in the neonatal period or in case of prematurity. The American Academy of Pediatrics (2012) rates it as a maternal medication that is usually compatible with breastfeeding.
