So, when med lists like these posted, how can we come to an a priori conclusion about what is and is not appropriate for the patient without having reviewed the relevant medical history and conducting a face to face evaluation?
True, but a phenomenon that happens in psychiatry, unfortunately all too often, is some psychiatrist decides to medicate someone with an Axis II trait or disorder (without a real Axis I, or the Axis I is under control and they try to then control the Axis II with meds), where meds don't really help that problem. Classically, I've seen this usually happen with a borderline PD patient who has a doctor that incorrectly diagnosed the person with bipolar DO and medicates them into zombie-land.
On occasion, I have seen an Axis II trait improve with a med but if this is the case-fine, but if the med doesn't work, it should be stopped. Unfortunately I've seen several doctors put a patient on a polypharm regimen where nothing, I mean nothing worked and they continued this expensive and actually medically harmful regimen on the patient.
I have actually had a few patients on tremendous polypharmacy that I felt was justified. E.g. I had one patient on a high dose of lithium, Depakote, Zyprexa, Haldol, and a low dose of Klonopin and she was still manic, just that on those meds she wasn't quite as bad (e.g. attacking someone every few days vs. several times a day)/ The only times I've encountered patients on tremendous polypharmacy where I thought it was justified was on a long-term unit, or having a patient in the community that was discharged from a long-term unit.
Such patients, unfortunately, often times only get stabilized with heavy duty treatment such as, ECT, Clozaril, or heavy duty polypharm with the biggest guns (e.g. Zyprexa, Lithium, Depakote, and a typical antipsychotic all at high dosages). They are, however, still the extreme minority, and if polypharmacy is the only thing that works well, the treating doctor needs to document and justify this so the next doctor won't think the previous one was just needlessly over-medicating the patient.
But getting back to the point, the ratio of over-medicating vs. justifiably using a lot of meds is tipped way over to the over-medicating side IMHO. It's to the point where I will highly suspect over-medicating if I ever see a patient on more than 3 meds, especially if that person has an Axis II disorder, and one of those meds is a benzo.
