Conjugated estrogens topical Breastfeeding Warnings

There are no data on the excretion of conjugated estrogens into human milk. The American Academy of Pediatrics considers estradiol, another estrogenic agent, to be compatible with breast-feeding. The manufacturer recommends that due to the potential for serious adverse reactions in nursing infants, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
