The researchers found no significant association between use of antipsychotics and increased risk of committing a homicide. However, a slightly increased risk of committing a homicide (31% increased risk) was associated with antidepressant use.
Use of benzodiazepines to treat anxiety and insomnia was associated with a significantly increased risk (45% increase in risk) of committing a homicide, while the greatest increased risk was associated with opiate painkillers (92% elevated risk) and anti-inflammatory painkillers (206% increased risk).
Wow!!!
