Read the Comment.

Central stimulant, selective inhibitor of dopamine and norepinephrine reuptake. It is the R enantiomer of modafinil, with similar pharmacological properties and effects as modafinil, since it is its active metabolite.
Used in narcolepsy.
Oral administration in onedaily dose.

Modafinil is excreted in breastmilk in clinically insignificant amounts (Aurora 2018) and no problems have been observed in six infants whose mothers were taking modafinil (Calvo 2018).

Modafinil can reduce prolactin levels (Samuels 2006).

A mother reported nervousness and sleeping difficulties in her breastfed daughters, which forced her to suspend treatment (age of girls and doses unspecified).

Until there is further published data on this drug in relation to breastfeeding, known safer alternatives may be preferable, especially during the neonatal period and in cases of prematurity.
