Drug Levels and Effects
Summary of Use during Lactation
Because no information is available on the use of ethacrynic acid during breastfeeding and because intense diuresis might decrease lactation, an alternate drug may be preferred, especially while nursing a newborn or preterm infant. Low doses of ethacrynic acid may not suppress lactation.

Effects on Lactation and Breastmilk
Ethacrynic acid was reportedly used successfully to suppress lactation in 6 postpartum women who did not want to breastfeed and to decrease the intensity of milk production in another.[1] The added contribution of the diuretic to the other measures, which are effective in suppressing lactation, has not been studied. No data exist on the effects of loop diuretics on established, ongoing lactation.
