This substance rises prolactinemia which can cause gynecomastia and galactorrhea in some patients.

Warning of the manufacturer:

It is unknown whether risperidone is excreted in human milk. In animal studies, risperidone and 9-hydroxy-risperidone are excreted in human milk. Consequently, this drug should not be administered to women during lactation.
