During this review of spontaneous postmarketing reports, we noted a variety of neurologic or psychiatric adverse events associated with use of these products. Reports included: agitation, aggressive behavior or hostility, anxiousness, depression, disorientation, disturbance in attention, dream abnormalities, hallucinations, insomnia, irritability, memory impairment, restlessness, somnambulism, suicidal thinking and behavior including suicide and tremor. Some of these reports appeared to be consistent with a drug-induced effect. Events were noted in both adults and children, and the onset of events varied.
