dont take this as medical advice, but i have read many places that bipolar meds also work for borderline personality disorder.
BPD is associated with rapid mood swings and so is Bipolar disorder. i have read that depakote treats both. check it out... run a web search for borderline meds and keep searching....
i know people who have BPD who take depakote and also xanax......
i think that pdoc's opinion is crap
