This is a very complicated subject because well let's be honest, some people need to be on a lot of meds. I do believe most do not. I try to stay as low as possible! The bare bones if you will. I think Big Pharm is partially to blame and a lof of pdocs who mean well are deceived by Big Pharm! Case in point, Buspar which does horrible in every study, barely beating the placebo, yet is prefered by many pdocs over benzos because it's not addicting, never mind the side effects or uselessness to most patients who are forced to try it. I'm sure that they cost more then benzo's has nothing to do with it lol.
Another case in point, mood stabilizers and anti-psychotics. There is no reason to be on BOTH unless your prong to hallucinate and get psychotic. Anti-depressants are perhaps the worse of the bunch. Totally useless for most people, yet it is a great market place for Big Pharm.
You end up with 1 mood stabilizer plus 1 anti-psychotic plus buspar and of course benzo's as need because we really know buspar doesn't work that well. Let's also throw in at least one AD just for good measure. What you end up with more times then not is a over med person feeling worse or like a zombie.
I take wellbutrin and klonopin most of the time, that's all. And occasionally a mood stabilizer and for short term until I feel better then I stop the MS. I refuse to take anti-psychotics or any useless AD's or anxiety med substitutes for the real thing.
So I would agree that most people are way over med, but some really do need to be too. Also add to this mix other meds, pain killers, anti-seizure meds and other meds for other medical problems on top of the psych meds, you could easily be up to 10 different meds a day
Just my 2 cents but there u have it
