Is Enalapril compatible with breastfeeding? Do we have alternatives for Enalapril?


June 9, 2018 (Very Low Risk)

Enalapril is an angiotensin converting enzyme (ACE) inhibitor used in the treatment of high blood pressure and heart failure.
Oral administration every 12-24 hours.

It is excreted in breastmilk in clinically insignificant amounts (Anderson 2018, Serrano 2015, Rush 1991, Redman 1990, Kirsten 1998, Huttunen 1989) and no problems have been observed in infants whose mothers were taking it (Anderson 2018, Rush 1991, Huttunen 1989 ), nor problems in the establishment of breastfeeding (Bach 1995).

It use is authorized in small infants and, off-label, in neonates. (FDA 2018, Kirsten 1998)

Due to its possible renal toxicity in preterm infants, it is preferable to avoid its use during the neonatal period in the case of prematurity. (Serrano 2015).

Expert authors and medical associations such as the American Academy of Pediatrics consider it to be a drug which is usually compatible with breastfeeding (Serrano 2015, Rowe 2013, Dennis 2012, Ghanem 2008, AAP 2001, Kirsten 1998).

The protective role of breastfeeding against maternal hypertension has been proven (Park 2018).


We do not have alternatives for Enalapril since it is relatively safe.
