In my 2004 edition of Hale (don't have the newer one here)  he mentions one study that found that very high doses--(which he delineates as 600 mg/day) suppress prolactin secretion and therefore milk production, but that this study had since been refuted in two others.  Hale goes on to state that it is not adviseable to take more than 25 mg/day; it is ranked as an L2 BUT AS L4 IN HIGH DOSEs, and is secreted in milk in direct proportion to mother's intake.  He states excessive oral doses"have been reported to produce sedation, hypotonia, and respiratory distress in infants although none have been reported via breastmilk"

"Physician, first do no harm...."  This sounds like a doc that read some brief mention of the high dose lowering prolactin study in a periodical and latched onto it.  Where's the evidence-based practice?  I'd be scared to death of this guy.
