When you read about doctors prescribing Prozac and Ritalin to four-year-old children because they're running around, annoying mommy, it's clear that something is amiss. The three big interacting aspects, as I see it, are the belief that medications already exist that will make everything perfect and the drug company's incredibly good job of reinforcing this can-do idea; second, the ridiculous time pressure put on doctors to make a diagnosis and "treat" the patient; and third, the inevitable fallibility of humans, doctors being human too.
Have you ever had a dead battery in your car? How many times did you turn the key, waiting for it to spark? Once? Twice? No, you kept cranking away, not believing your own senses could be wrong... and when a doctor makes a whizzy diagnosis and 25mg of amitriptyline does nothing, and 50 mg does nothing, the natural, human tendency is to try 100mg. If you went in to see a doctor and you only had fifteen minutes to tell him everything bad that had ever happened to you (in fifteen minutes), with no way for him to evaluate that against everything else going on in your life, what would he do? If he was a carpenter, he'd hit you with his hammer, and if he's a psychiatrist, his hammer is drugs..... and in America, we can fix everything that's wrong! We just need the right hammer! They had G on two separate anti-psychotics, so strong his hair fell out? Not right, a doctor shouldn't have to use that as a diagnostic tool. I admit, I have a dog in the fight - my sister went into treatment for bipolar disorder back in the dark 1980's, and she now has "tardive dyskinesia."

What "tardive dyskinesia" is, is a name that doctors made up to obviate or obscure the fact that they had doled out medicine so strong it's caused permanent neurological damage. If your neighbor whacked you with a dead squirrel and forever after you vibrated like a Parkinson's disease sufferer, you'd be mad at your neighbor, or at least the squirrel, right? That's what people with tardive dyskinesia do, shake and shake and shake. The doctors treating my sister meant well - but if she had a choice, she wouldn't have been so trusting in their "knowledge." Again, I feel as a bottom line, anti-psychotics should be used for one thing and one thing only, at least until each one is proven safe.
The "off-label" prescribing of drugs has gotten so ridiculous that it's actually the drug companies that are inventing new diseases just to use up their products. Nobody - but NOBODY, except readers of obscure journals - had ever heard of "restless leg syndrome" until GlaxoSmithKline got a bug up their butt to crank up the sales of Requip. If you do some research on the marketing of pharmaceuticals, including the doctor's educational seminars at golf resorts in the Caribbean and the "honorariums" (AKA "bribes") they get paid for pushing off-label dope, you may be rather shocked at the amazing lack of ethics.
I don't mind the off-topicness if it's helpful.... it's a scary world, you know? I'm certainly not anti-medicine, I take several, but what I am saying is that if you want the best, most informed treatment for any old thing, it's YOU who needs to get as informed as you possibly can, because the doctors just don't have the time anymore. And they don't like it either, they're caught in the jaws of the same insurance co. monster as we are.
