Though antidepressants are prescribed for people with varying degrees of depression, new research suggests that only people who suffer from severe depression are helped by the drugs. British scientists analyzed data from 35 clinical trials submitted to U.S. health regulators on antidepressants such as Prozac, Paxil, and Effexor. The researchers found that patients with mild or moderate depression received no better relief from antidepressants than they did with a placebo, while severely depressed patients were helped by the drugs.
