It is excreted in breast milk in clinically insignificant amounts (AEMPS 2021, Lundbeck 2020, Matheson 1988, Kirk 1980) and no problems have been observed in infants whose mothers have taken it (Matheson 1988. Plasma levels in these infants were very low. (Matheson 1988)

May increase prolactin levels and cause galactorrhea. (Bostwick 2009, Kropp 2004)

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it.
