CT and magnetic resonance imaging revealed minimal asymmetry of temporal horn size, the right being greater than the left, but both scans were otherwise unremarkable. Neuropsychological testing was performed on three separate occasions over a S-year period and each time revealed diffuse cerebral dysfunction. Oven the course of several prolonged hospitalizations, Ms. A’s condition was stabilized with a combination of fluphenazine, S mg b.i.d.; benztropine, 1 mg b.i.d.; lithium carbonate, 600 mg b.i.d.; carbamazepine, 400 mg b.i.d.; and propranolol, 120 mg b.i.d. Carbamazepine levels were in the range of 5-8 ig/ml, and the patient was without clinical seizures or violent episodes for 8 months. However, because of her hypercholesterotemia, an attempt was made to taper Ms. A’s dose of propranolol. This was done over a 2-week period without evidence of rebound hypertension while she was in the hospital. Co-

Ms. A, a 51-year-old woman, had a 3-year history of migraine-like headaches attributed to the onset of fibromyositis and had been treated for 3 years with alprazolam, 13 mg/day, and doxepin, 100 mg at bedtime. She was hospitalized for ahprazoham withdrawal. She was placed on a regimen of atprazolam, 1 1 mg/day, on hospital day 2, along with phenobarbital, 120 mg/day. The alprazolam

was tapered by means of a 2-mg decrease the last dose was given on hospital day

every third day; 24. She was pre-

scribed phenobarbital, 90 mg/day for days 2 through 25, 60 mg/day for days 26 and 27, and 30 mg/day for days 28 and 29. Doxepin, 100 mg, was continued throughout the hospital stay. Her vital signs remained stable, and she cxhibited no signs or symptoms of withdrawal. She was discharged from the hospital on day 30. Ms. B, a 33-year-old woman, had a 1-year history of back pain. She was prescribed alprazolam and a combination of propoxyphene, 100 mg, and acetaminophen, 650 mg. She gradually increased the alprazolam to 15-20 mg/ day and the propoxyphene-acetaminophen to 20-30 tab-

Fluvoxamine may be capable of precipitating mania, as is the analogue fluoxetine (2-4). Perse et al. (5) reported mania in a woman with obsessive-compulsive disorder and bipolar affective disorder who was treated with fluvoxamine. Investigators should be aware of the potential switch effect of this drug, which, hike fluoxetine, appears nonlethal in massive overdose.
