In Britain, researchers from Cardiff University have looked into the link between hostile and aggressive acts and antidepressant selective serotonin reuptake inhibitor (SSRI) medications. The research found that individuals on Paxil, and its generic paroxetine, have twice the risk for violent behavior, aggression and hostility than those not on SSRI antidepressant medications. Currently, 1.5 million children are on antidepressant medications. In 2008, consumer advocates and parent’s right organizations called on Congress to explore the link between psychiatric medications, school shootings, and the harmful aggressive side effects of psychotropic medications. Advocates for reform are calling on Congress to mandate “black box” warnings to include mania, psychosis, hostility, hallucinations and homicidal behavior—to the current warnings regarding suicide.
