Do Antidepressants Work?

A question mark formed from pills and capsulesAccording to the Mayo Clinic, about 13% of Americans—more than 1 in 10—take an antidepressant…
A 2008 study led by Dr. Irving Kirsch of Harvard Medical School started a big ruckus in the mental health world.  He and his colleagues re-analyzed 35 different antidepressant drug trials submitted to the FDA for the licensing of Prozac, Effexor, Serzone, and Paxil.   He used the Freedom of Information Act to get access not only to the studies that showed the drugs worked, but also to the studies that didn’t show an effect, which were, unfortunately, most of them.

In 1928, for example, four men agreed to be part of a hair regrowth study attempting to settle the matter. The men shaved a portion of their faces in one downward stroke using the same brand of shaving soap, fresh razors and water at a constant temperature—all in the name of science.
