title: The abrupt discontinuation of fluvoxamine in patients with panic disorder.
abstract: BACKGROUND
  We evaluated patients abruptly withdrawn from fluvoxamine, a serotonin selective reuptake inhibitor, for evidence of a discontinuation syndrome.
  
  
  METHODS
  In an open-label study, 14 subjects were abruptly withdrawn from fluvoxamine after treatment lasting 8 months (7 months for 1 patient). Psychological, somatic, and perceptual symptoms were assessed at Day 5, Day 10, and Day 14 postdiscontinuation. Anxiety and depression were assessed using clinician and self-rated scales.
  
  
  RESULTS
  Twelve (86%) of 14 subjects developed new symptoms. The most frequent symptoms reported were dizziness/incoordination, headaches, nausea, and irritability. Symptoms peaked on Day 5 postdiscontinuation. Only 1 subject had a recurrence of panic, but another developed anxiety and depression; both were remedicated.
  
  
  CONCLUSIONS
  Abrupt fluvoxamine discontinuation is associated with a characteristic syndrome in many patients.
