Prozac, the bestselling antidepressant taken by 40 million people worldwide, does not work and nor do similar drugs in the same class, according to a major review released today. The study examined all available data on the drugs, including results from clinical trials that the manufacturers chose not to publish at the time. The trials compared the effect on patients taking the drugs with those given a placebo or sugar pill. When all the data was pulled together, it appeared that patients had improved - but those on placebo improved just as much as those on the drugs. The only exception is in the most severely depressed patients, according to the authors - Prof Irving Kirsch from the department of psychology at Hull University and colleagues in the US and Canada. But that is probably because the placebo stopped working so well, they say, rather than the drugs having worked better. "Given these results, there seems little reason to prescribe antidepressant medication to any but the most severely depressed patients, unless alternative treatments have failed," says Kirsch. "This study raises serious issues that need to be addressed surrounding drug licensing and how drug trial data is reported." The paper, published today in the journal PLoS (Public Library of Science) Medicine, is likely to have a significant impact on the prescribing of the drugs. The National Institute for Health and Clinical Excellence already recommends that counselling should be tried before doctors prescribe antidepressants.
