Nonetheless, a few guidelines should be mentioned and these are elaborated in more detail elsewhere [89]:
1.
There should be a frank discussion of what the patient means when she uses the word depression, and if appropriate, there should be further discussion about how the depression that the patient is suffering differs from that in a major depressive episode. This discussion can address the fact that antidepressant medication effectiveness has been shown in the specific depressive entity of major depressive disorder, but there is little evidence for medication effectiveness in other “depressions.” This does not mean that medications or some medication will not be tried and might even turn out to be helpful, but the benefits one might receive will usually be quite modest at best.
2.
Elaborating on the point made above, the patient needs to be told that since the research for effectiveness for these drugs reveals modest effect at best, the greatest amount of progress and improvement will come from the psychotherapeutic work. This does not mean that patients will get no benefit from pharmacologic treatment, but they should work towards not idealizing the pharmacology or any particular pharmacologic agent.
3.
There is no data that supports the use of polypharmacy, and it is best to treat with one medication, to appreciate the targeted outcome with or for that medication, and, if after the medication has been tried for a sufficient amount of time, to stop that medication before starting another one. There is no evidence for augmentation of medications in BPD.
4.
It is important that all these discussions take place an appreciation by the patient that one of the diagnoses being considered is BPD. In fact such discussions should take place at the initiation of psychopharmacologic treatment [41].
The prescriber should not assume that the patient already has this knowledge, as the patient’s prior experience may have been with a psychiatrist who believed that the patient had treatment-resistant affective illness and approached treatment from the position that finding the right combination of medications is all that the patient needed in order to improve.
