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


August 28, 2018 (Very Low Risk)

Captopril is an angiotensin converting enzyme (ACE) inhibitor used in the treatment of hypertension, heart failure, myocardial infarction and type I diabetic nephropathy.
Oral administration every 8-12-24 hours.

It is excreted in breastmilk in clinically insignificant amounts (Anderson 2018, FT 2018, Serrano 2015, Drummer 1986, Devlin 1981) and no problems have been observed in infants whose mothers were taking it (Anderson 2018, Devlin 1981).

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).
List of WHO essential medicines: compatible with breastfeeding (WHO / UNICEF 2002).

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


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