I remember talking to a GI (gastro-intestinal) MD about a year or two ago that said that milk production had indeed been a "negative" side-effect of his patients taking Reglan. It certainly would be for non-lactating folks! His only response about giving it to our lactating moms was that it could lead to depression in the long-term. And, as stated by someone else, the milk production decreases as the patient is weaned from it. Janet
