The Washington Post is reporting that the makers of popular antidepressant drugs are refusing to disclose the results of clinical trials involving depressed children. Doctors say the studies may prove that drugs such as Paxil. Zoloft and Effexor, may cause children to become suicidal. Researches familiar with the studies show that children who take the drugs did not get any better than children taking dummy pills. The drug companies say the studies are trade secrets.
