In some cases, anti-depressants kill. It has been shown that people who are on antidepressants are statistically more likely to kill themselves than people who are not. This is explained away as ‘people who are depressed are more likely to kill themselves in the first place’, although all people in the sample were depressed, and as ‘it gets worse before it gets better’- but if getting worse means jumping off a building, it doesn’t leave much room for improvement afterwards.
And is it a coincidence that virtually all school shootings were committed by teens who were on antidepressants? I only say virtually to leave room for the possibility that some did not involve meds, although personally I have not encountered such a case to date.
Here are some links someone sent me with further evidence that anti-depressants are associated with not only suicide, but psychosis, occasionally leading to murder.
These last two are talking about a scholarly article that I have access to on ProQuest from my school and I could email you the full text with graphs if you need so you have the root source.
The article is Selective Publication of Antidepressant Trials and Its Influence on Apparent Efficacy in NEJM.
