Hydralazine and pregnancy often do not mix, although there are exceptions to this rule. Specifically, hydralazine has an FDA pregnancy rating of “C.” That rating means some non-human animal testing shows it can potentially affect the development of a fetus. That said, medical providers sometimes prescribe it during pregnancy when high blood pressure due to preeclampsia or eclampsia develops. These conditions are life-threatening, so taking the medication is worth any potential risk.Â
Hydralazine and Breastfeeding
Hydralazine is excreted into breast milk. Studies do show, however, that hydralazine poses little risk to the infant. That said, lactating parents should still talk to their medical providers about using this drug before breastfeeding.
