That study finds anti-depressant medications appear to help only very severely depressed people and work no better than placebos in many patients.
This review of several studies by the University of Hull looked at four anti-depressants examining whether a patient's response to these drugs hinged on how depressed they were before getting treatment. They were Prozac, Effexor , Paxil and Serzone. Researchers found that, compared with placebos, these new generation anti-depressant medications only provided significant benefits in the most severely depressed.
But a spokesperson for Paxil says the study only examined a small subset of the total data available.
