image There are some confusing headlines in today’s papers which will send the manufacturers of Prozac and other antidepressants in a spin.

A clinical trial has concluded that placebos worked as effectively as anti-depressants. Researchers found that the drugs had no more effect than a placebo for mildly depressed patients, and for most people suffering severe depression.

So does this mean that thousands of patients are taking these drugs, which could have severe side effects, unnecessarily? Are you, like me, confused about what it means?

A group of experts, led by Prof Irving Kirsch, from the Department of Psychology at the University of Hull, analysed 47 clinical trials using data released under Freedom of Information rules by the US Food and Drug Administration. They found little evidence of benefit when analysing both unpublished and published data from the drug companies.

Does these findings mean that antidepressants do not work? I don’t think that is what they were saying, they found that the anti depressants did work, but then so “did” the dummy drugs.

More than 31 million prescriptions for drugs such as Prozac were issued in England in 2006 – a 6% rise on the year before – and a record high, despite national guidance advocating alternative treatments. I wonder how doctors will view these results, it must be confusing for them too.

So does Prozac and other depressants work? Or should doctors be prescribing counselling and alternative treatment instead, such as exercise?
