Five patients with hepatitis C (HCV), three of whom were treated with peginterferon alfa-2 (IFN) and two who were not treated with IFN, developed homicidal ideation (HI) during a 4-year period. Following accepted rules for determining causation, there appeared to be a causal relatedness between IFN use and the development of homicidal ideation for those patients taking IFN. None of these patients attempted a homicidal act while on treatment with IFN, nor in the follow-up period after treatment. The incidence of HI while treated with IFN in our patient population is estimated to be less than 1%. The abil- ity of prescription medication to cause homicidal ideation is reviewed, and legal implica- tions are discussed.

Recently, there has been an increased awareness of the ability of antidepressant medications to cause a paradoxical increase in depression and, in some cases, suicidal ideation (SI) (Breggin, 2003, 2008; Food and Drug Administration, 2005a; Healey, Herxheimer, & Menkes, 2006; Khan, 2002; Marks, 2004). The clinical pharmacology and mechanism of the later effect may be related to the known ability of medications in the SSRI class to cause or exacerbate levels of anxiety, agitation, irritability, akathisia, aggression, hostility, emotional blunting, and disinhibition. Clini- cally all of these phenomena have been associated with violence. It is reasonable from a psychological perspective to understand how a medication that can induce or increase feel- ings of anxiety, agitation, akathisia, aggression, hostility, irritability, and/or disinhibition could lead toward self-directed or outwardly directed violence in a predisposed individual.
