Is Torsemide safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Torsemide. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
Because little information is available on the use of torsemide 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 torsemide may not suppress lactation.
Effects on the breastfed infant

Effects on milk supply
Intense diuresis, fluid restriction and breast binding have been used to suppress lactation immediately postpartum.[1-4] The added contribution of the diuretic to the other measures, which are effective in suppressing lactation, has not been studied.
Women who delivered following pre-eclampsia were randomized to receive either torsemide 20 mg daily or placebo for 5 days starting within 24 hours after delivery. Eighty percent of the women who received torsemide and 75% of women who received placebo breastfed. One mother who received torsemide and none who received placebo reported a decrease in breastmilk.[5]
