Studies suggest that the popular drugs are no more effective than a placebo. In fact, they may be worse.
Although the year is young, it has already brought my first moral dilemma. In early January a friend mentioned that his New Year’s resolution was to beat his chronic depression once and for all. Over the years he had tried a medicine chest’s worth of antidepressants, but none had really helped in any enduring way, and when the side effects became so unpleasant that he stopped taking them, the withdrawal symptoms (cramps, dizziness, headaches) were torture. Did I know of any research that might help him decide whether a new antidepressant his doctor recommended might finally lift his chronic darkness at noon?
The moral dilemma was this: oh, yes, I knew of 20-plus years of research on antidepressants, from the old tricyclics to the newer selective serotonin reuptake inhibitors (SSRIs) that target serotonin (Zoloft, Paxil, and the granddaddy of them all, Prozac, as well as their generic descendants) to even newer ones that also target norepinephrine (Effexor, Wellbutrin). The research had shown that antidepressants help about three quarters of people with depression who take them, a consistent finding that serves as the basis for the oft-repeated mantra “There is no question that the safety and efficacy of antidepressants rest on solid scientific evidence,” as psychiatry professor Richard Friedman of Weill Cornell Medical College recently wrote in The New York Times. But ever since a seminal study in 1998, whose findings were reinforced by landmark research in The Journal of the American Medical Association last month, that evidence has come with a big asterisk. Yes, the drugs are effective, in that they lift depression in most patients. But that benefit is hardly more than what patients get when they, unknowingly and as part of a study, take a dummy pill—a placebo. As more and more scientists who study depression and the drugs that treat it are concluding, that suggests that antidepressants are basically expensive Tic Tacs.
Hence the moral dilemma. The placebo effect—that is, a medical benefit you get from an inert pill or other sham treatment—rests on the holy trinity of belief, expectation, and hope. But telling someone with depression who is being helped by antidepressants, or who (like my friend) hopes to be helped, threatens to topple the whole house of cards. Explain that it’s all in their heads, that the reason they’re benefiting is the same reason why Disney’s Dumbo could initially fly only with a feather clutched in his trunk—believing makes it so—and the magic dissipates like fairy dust in a windstorm. So rather than tell my friend all this, I chickened out. Sure, I said, there’s lots of research showing that a new kind of antidepressant might help you. Come, let me show you the studies on PubMed.
It seems I am not alone in having moral qualms about blowing the whistle on antidepressants. That first analysis, in 1998, examined 38 manufacturer-sponsored studies involving just over 3,000 depressed patients. The authors, psychology researchers Irving Kirsch and Guy Sapirstein of the University of Connecticut, saw—as everyone else had—that patients did improve, often substantially, on SSRIs, tricyclics, and even MAO inhibitors, a class of antidepressants that dates from the 1950s. This improvement, demonstrated in scores of clinical trials, is the basis for the ubiquitous claim that antidepressants work. But when Kirsch compared the improvement in patients taking the drugs with the improvement in those taking dummy pills—clinical trials typically compare an experimental drug with a placebo—he saw that the difference was minuscule. Patients on a placebo improved about 75 percent as much as those on drugs. Put another way, three quarters of the benefit from antidepressants seems to be a placebo effect. “We wondered, what’s going on?” recalls Kirsch, who is now at the University of Hull in England. “These are supposed to be wonder drugs and have huge effects.”
The study’s impact? The number of Americans taking antidepressants doubled in a decade, from 13.3 million in 1996 to 27 million in 2005.
To be sure, the drugs have helped tens of millions of people, and Kirsch certainly does not advocate that patients suffering from depression stop taking the drugs. On the contrary. But they are not necessarily the best first choice. Psychotherapy, for instance, works for moderate, severe, and even very severe depression. And although for some patients, psychotherapy in combination with an initial course of prescription antidepressants works even better, the question is, how do the drugs work? Kirsch’s study and, now, others conclude that the lion’s share of the drugs’ effect comes from the fact that patients expect to be helped by them, and not from any direct chemical action on the brain, especially for anything short of very severe depression.
As the inexorable rise in the use of antidepressants suggests, that conclusion can’t hold a candle to the simplistic “antidepressants work!” (unstated corollary: “but don’t ask how”) message. Part of the resistance to Kirsch’s findings has been due to his less-than-retiring nature. He didn’t win many friends with the cheeky title of the paper, “Listening to Prozac but Hearing Placebo.” Nor did it inspire confidence that the editors of the journal Prevention & Treatment ran a warning with his paper, saying it used meta-analysis “controversially.” Al-though some of the six invited commentaries agreed with Kirsch, others were scathing, accusing him of bias and saying the studies he analyzed were flawed (an odd charge for defenders of antidepressants, since the studies were the basis for the Food and Drug Administration’s approval of the drugs). One criticism, however, could not be refuted: Kirsch had analyzed only some studies of antidepressants. Maybe if he included them all, the drugs would emerge head and shoulders superior to placebos.

Far too many Americans go straight to antidepressants and never are even given the opportunity to work on themselves. Changing your approach to depression and anxiety alone is the first step.Exercise, proper diet, Emotional Freedom Technique and mindful meditation are all extremely effective in combating anxiety and depression. Truly invest in your personal development, create abundance and wipe out negativity once and for all.
This post made me realize how often I have taken laughter and the simple things in life for granted, not truly appreciating them. Laughter is such a simple thing but yet so very profound. It can completely change your mood and turn an tough day into a better if not outright great day.
