In my post of February 16 of this year, Antipsychotics Are For Psychosis, Not Insomnia, I reported on the increasing off-label (non FDA-approved) prescription of so-called atypical antipsychotic medication for insomnia and anxiety, despite the risk these drugs pose of causing metabolic syndrome (diabetes, obesity, and increased blood cholesterol and triglycerides [blood fats]) as well as an irreversible neurological problem called tardive dyskinesia.
Somehow doctors - mostly primary practitioners but many psychiatrists as well - have been brainwashed into thinking that this risk is somehow much less than the risks posed by addiction from sedatives and hypnotics - the old fashioned tranquilizers and sleeping pills. (Tranquilizers and sleeping pills are actually one and the same thing, by the way. What's the difference? Marketing. Some of these drugs are marketed for sleep and some for anxiety, but they all do both of these things).
Anyway, a class of drugs called benzodiazepines are the most commonly used drugs indicated for insomnia and anxiety. These include drugs like Valium, Librium, Ativan, Klonopin, Dalmane, Restoril, and Xanax. They replaced the far more addictive and dangerous barbiturates several decades ago.
A newer (and of course much more expensive) group of drugs (Ambien, Lunesta and Sonata) were marketed as being "different" from the other benzodiazepines, so many doctors are much less afraid of prescribing them than the old drugs.
In truth, these drugs work almost exactly the same way as the older benzo's. They also cause sleepwalking. And they are every bit as addictive. In fact, according to my prime source for all things concerning drug abuse, Rolling Stone magazine, the latest fad in D.C. is staying awake while on Ambien. Apparently, you can get really high if you do that. (Now that you know, please don't go out and do it!)
Of course, mild and moderate anxiety and insomnia can often be treated without any medication at all, but don't even get me started on that.
Actually, benzo's (with the possible exception of Xanax, which is very short acting), are not abused by themselves very much at all by addicts. When was the last time you read a horror story in the news about valium addiction? It is also almost impossible to die from a benzo overdose if no other drugs are taken with them.
The drugs can create trouble, however, when they are combined with opiates - in which case one can overdose on the combination and die. Unfortunately, this has been happening with increasing frequency lately. But I digress.
Not only are benzo's by themselves pretty safe, but they have almost no side effects at all except in the elderly. Compare their risks with the risks of atypical antipsychotics, and it is absolutely no contest at all. Personally, if I had to choose, I would much prefer to be addicted to a benzo than be addicted to insulin shots!
Despite this obvious discrepancy in the risks, the problem of the misuse of prescriptions for antipsychotics by physicians to treat insomnia and anxiety continues to worsen. In the September 2, 2011 issue of Psychiatric News, an American Psychiatric Association newspaper, there were two headlines side by side: "Antipsychotics Increasingly Prescribed for Anxiety" and "Concern Raised Over Antipsychotic Use for Sleep Problems."
Even well known drug company apologist Charles Nemeroff was quoted as bemoaning the use of antipsychotics for anxiety disorders like panic disorder.
For insomnia, the biggest seller is the drug Seroquel (Quetiapine), which is second only to Zyprexa (Olanzepine) in causing metabolic syndrome. Indeed, Seroquel is probably the most sedating atypical. The article in the paper pointed out that a lot of physicians who prescribe this medication do not even bother to monitor the patient for increases in weight, blood sugar, and serum fats.
The article about insomnia was prompted a large increase in prescriptions for this drug for insomnia in military personel. According to the Department of Defense, in 2001 20-30 soldiers per ten thousand were treated for insomnia. By 2009, the figure had soared to 226 per ten thousand. 57% of all prescriptions of Seroquel were for insomnia!
Soldiers reported gaining an average of 6.3 pounds each on the drug. Only 61% had a check of their blood sugar within six months of starting the medication. Fortunately, no actual cases of diabetes were found. The author of the study that generated these statistics agreed with my theory that these drugs were being used by physicians instead of benzo's because of fear of addiction.
That reasoning is a bit like the reasoning of people who will not fly in a commercial airplane for fear of a crash, but refuse to use seatbelts when they ride in a car. These doctors apparently are completely clueless when it comes to evaluating relative risks.
