OBJECTIVE: To inform clinicians of the possibility that seizures due to the
rapeutic doses of fluvoxamine may not be as rare as previously considered.
CASE SUMMARY: A 49-year-old white man with schizoaffective disorder and a p
ast history of seizures secondary to head trauma had been seizure-free for
approximately 10 years. Fluvoxamine therapy was begun due to increasing obs
essive-compulsive behavior. Despite receiving anticonvulsants for this mood
disorder, the patient had a breakthrough seizure. There were no underlying
medical conditions that might have induced this seizure. No further seizur
es occurred after he was placed on a higher dosage of the anticonvulsants.
The obsessive-compulsive behavior improved considerably as a result of fluv
oxamine treatment.
DISCUSSION: The patient presented here developed a seizure with a therapeut
ic dosage of fluvoxamine; seizures associated with this agent have occurred
more often with overdose. Multiple factors such as a prior history of seiz
ures, head trauma, and concurrent treatment with other psychotropic agents
are considered in this case report.
CONCLUSIONS: Despite the relatively safe and benign adverse effect profile
of the selective serotonin-reuptake inhibitors such as fluvoxamine, clinici
ans should be cautious about seizures as an adverse effect, especially when
the patient has even a remote history of seizure or head trauma.
