Drug Levels and Effects

Summary of Use during Lactation

No information is available on the use of fenoldopam during breastfeeding. The manufacturer recommends avoiding breastfeeding during fenoldopam use; however, because of its poor oral bioavailability and short half-life, any fenoldopam in milk is unlikely to adversely affect the breastfed infant. Also, fenoldopam can be given intravenously to infants. Unlike dopamine, it does not decrease serum prolactin concentrations and might not interfere with nursing.

Effects on Lactation and Breastmilk

Relevant published information in nursing mothers was not found as of the revision date. Unlike dopamine, fenoldopam infusion does not affect serum prolactin concentration in normal women.[1] The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
