I can tell you that this happened to me with risperidone.

I can also tell you that I nursed my son 3 years ago, and to this day I can still get a few drops out if I try. However you should not be leaking at this point I wouldn't think - getting milk with pressure in the form of a couple drops is one thing, and normal for some women, but for constant leakage or any type of large fluid volume I would see the doc again. It could be a simple hormone problem that stuck with the antipsychotic.Would likely be easily fixable with the right medication.
