Is Spironolactone Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Spironolactone? Is Spironolactone safe for nursing mother and child? Does Spironolactone extracts into breast milk? Does Spironolactone has any long term or short term side effects on infants? Can Spironolactone influence milk supply or can Spironolactone decrease milk supply in lactating mothers?

A diuretic which is antagonist of Aldosterone receptor and a potassium-sparing drug. Excretion into breast milk is clinically non-significant and without side-effects observed in breastfed infants of treated mothers. A medication which is used for treatment of infants even in the neonatal period. It decreases slightly the secretion of Prolactin, however, instead other diuretic drugs, a suppressive effect on lactation has not been reported. The American Academy of Pediatrics (2001) rates it as Medication Usually Compatible With Breastfeeding. Eleventh WHO Model List of Essential Drugs 2002: Compatible with breastfeeding.

Spironolactone appears acceptable to use during breastfeeding.

In 17-day-old breastfed (extent not stated) infant whose mother was taking 25 mg of spironolactone 4 times daily since pregnancy, serum sodium and potassium remained normal.[1]Spironolactone 75 mg every other day was taken orally by a mother while nursing a newborn. She was also taking 400 mg of bretylium tosylate every 8 hours, atenolol 25 mg daily, propranolol 20 mg 3 times a day, and multivitamin, potassium and magnesium supplements. Jaundice, thought to be unrelated to the drug, occurred at 60 hours of age, but resolved. The infant had appropriate weight gain and development during the first 4 months of life.[2]

Intense diuresis can suppress lactation;[3][4] however, it is unlikely that spironolactone alone is sufficiently potent to cause this effect. Spironolactone can also cause gynecomastia.[5]
