MedWatch is the Food and Drug Administration's Safety Information and Adverse Event Reporting Program (AERS). If you think you or someone in your family has experienced an adverse reaction to taking a psychiatric drug, see this page for instructions on reporting the adverse event through your doctor or directly to the FDA using an online form.
A May 2006 USA Today article states that: "Drug companies are required to file any reports they have to the FDA, but consumers and doctors report such events on a voluntary basis. Studies suggest the FDA's Adverse Events Reporting System database captures only 1% to 10% of drug-induced side effects and deaths, "maybe even less than 1%," says clinical pharmacologist Alastair J.J. Wood, an associate dean at Vanderbilt Medical School in Nashville. So the real number of cases is almost certainly much higher."
