In theory, pharmaceutical companies are barred from selling a drug for any purpose other than the one that the F.D.A. has approved on the basis of clinical testing. But the reality is different.

The antidepressant Paxil was tested on adults but sold off-label to treat children. Seroquel, an anti-psychotic, was marketed as a treatment for depression. Physicians, often on retainer from pharmaceutical companies, are free to prescribe a drug for any reason if they entertain a belief that it will work.
