Is the use of antipsychotic or antidepressant drugs, particularly phenothiazines like thioridazine, associated with sudden unexpected death?
Phenothiazines, particularly thioridazine, are disproportionately associated with sudden unexpected death in psychiatric patients, likely due to their arrhythmogenic effects.
Mehtonen et al. (1991) conducted an observational in Sudden unexpected death (n=49). Phenothiazines (especially thioridazine) vs. Other antipsychotic or antidepressant drugs was evaluated on Sudden unexpected death. Among 49 cases of sudden death associated with psychotropic drugs, phenothiazines were involved in 46 cases, with thioridazine being the only antipsychotic associated with 15 cases.
