Psychiatric Drugs—Regulatory Warnings on Violence, Mania, Psychosis, Homicide
Fact: Despite 27 international drug regulatory warnings on psychiatric drugs citing effects of mania, hostility, violence and even homicidal ideation, and dozens of high profile shootings/killings tied to psychiatric drug use, there has yet to be a federal investigation on the link between psychiatric drugs and acts of senseless violence.
Fact: At least 37 school shootings and/or school-related acts of violence have been committed by those taking or withdrawing from psychiatric drugs resulting in 175 wounded and 82 killed (in other school shootings, information about their drug use was never made public—neither confirming or refuting if they were under the influence of prescribed drugs).
Fact: Between 2004 and 2012, there have been 14,773 reports to the U.S. FDA’s MedWatch system on psychiatric drugs causing violent side effects including: 1,531 cases of homicidal ideation/homicide, 3,287 cases of mania & 8,219 cases of aggression. Note: The FDA estimates that less than 1% of all serious events are ever reported to it, so the actual number of side effects occurring are most certainly higher.
School-related acts of violence aren’t the only cases commonly found to be under the influence of psychiatric drugs. There are 28 other acts of senseless violence committed by individuals taking or withdrawing from psychiatric drugs resulting in an additional 270 dead and 164 wounded.

Also, because methylphenidate can cause or worsen some psychiatric disorders (such as depression, suicidal thoughts, hostility, anxiety, agitation, psychosis and mania) patient’s “psychiatric well-being” should be monitored.

The committee also recommended strengthened warnings on the withdrawal symptoms of paroxetine, which are common.
