It is a non-steroidal anti-inflammatory which is derived from Flufenamic acid, topically used but it can also be orally or intravenously administered. At latest update relevant data related to breastfeeding were not found. However, we have information on its precursor the Flufenamic acid which is excreted into breast milk in non-significant amount and considered by the American Academy of Pediatrics as usual compatible with breastfeeding. Absorption from skin to the plasma has been reported. A high protein-binding capacity makes excretion into breast milk highly unlikely. However, it would be safer for both the mother and the infant the use of anti-inflammatory products with a proven safety while breastfeeding. Avoid the use on the nipple or on extensive skin areas or long-term treatments to prevent systemic absorption.
