We take it on trust that the drugs our doctors prescribe are safe and effective. But this special investigation exposes huge failings in the system of medicines regulation that is supposed to monitor drug safety. It reveals how patients' lives have been put at risk as a result. Panorama takes a unique journey inside the secret world of the medicines regulator and discovers that it's been sitting on crucial safety information about one of Britain's most widely-prescribed antidepressants for over a decade. For the last two years, Panorama has been investigating claims that Seroxat can cause addiction, self-harm, aggression and even suicide. The medicines regulator always denied there was evidence to back up these claims. But now the programme reveals that, not only is the evidence there, it's been lying dormant in the regulator's archive for at least 13 years.
