This prospective open-label study assessed the efficacy and tolerability of low-doze fluvoxamine in 14 children with pervasive developmental disorders (PDDs). Although there was no response for the group as a whole, eight subjects were considered at least partial responders in intent-to-treat analyses. Results suggest fluvoxamine can be beneficial in the treatment of select children and adolescents with PDDs. (Contains references.) (Author/DB)
