A case of serial nightmares and oneiroid state under paroxetine for senile depression

Abstract

We report on rare side effects of paroxetine. A 67-year-old female patient who had been suffering from prolonged depression for over a year but had not received appropriate treatment was administered 20-mg paroxetine daily. However, the patient required hospital admission after 16days because of behavioural disturbances and delusions that she was being chased by evil persons from a religious group. The delusions were ultimately confirmed to be serial nightmares and an oneiroid state. The nightmares gradually disappeared following discontinuation of paroxetine. The Adverse Drug Reaction Probability Scale showed a score of 6 (probable). Reports on paroxetine-induced nightmares are rare, and there is a possibility that, in this case, parexetine caused the nightmares in association with depression and assumed underlying brain dysfunction due to ageing. © 2012 The Authors.
