A display of hypomania in a depressed male in response to fluvoxamine.
The present report describes the behavioural and psychological changes in a 55-year-old depressed male who displayed hypomania after the use of fluvoxamine in addition to other antidepressant medications. The patient experienced his first major depressive episode after the bankruptcy of his company. When fluvoxamine was prescribed at a dose of 50 mg/day in addition to sulpiride at 150 mg/day and a 50 mg dose of trazodone before sleep seven months after admission, grinning and a violation of ward rules occurred repeatedly. The patient became verbally aggressive to the staff and addicted to gambling and alcohol. Six days after the cessation of fluvoxamine, his condition remitted. None of the neuromuscular abnormalities indicative of serotonin syndrome appeared during the episode. Upon review of previous reports on manic switches induced by SSRIs and other antidepressants, we speculate that the fluvoxamine accounted for his hypomania.
