Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

It is a reuptake-inhibitor of Serotonin and Norepinephrine.
Oral administration once a day.

Excreted into breast milk in clinically non-significant amount (Collin 2018, Andrade 2014, Rowe 2013, Boyce 2011, Berle 2011, Briggs 2009, EMA 2009, Lanza 2009, Lobo 2008) with no side-effects being observed in breastfed infants from treated mothers (Briggs 2009). Plasma level in those infants was very low or undetectable (Boyce 2011, Briggs 2009).

Because there is less experience published than with other antidepressants of the same pharmacological group, it should be preferred the use of an alternative drug that is known to be safer in the neonatal period or prematurity.

Galactorrhea has been observed with or without an increase in prolactin (Demirci 2015, Belli 2013, Korkmaz 2011), but less frequently than with other antidepressants (Trenque 2011).

Women who use antidepressant medication during pregnancy are in need of more support for breastfeeding since they are at risk for early weaning (Leggett 2017).
