Treating functional impairment of autism with selective serotonin-reuptake inhibitors

OBJECTIVE: To review literature describing use of selective serotonin-reuptake inhibitors (SSRIs) in the management of functional impairments associated with autistic disorder. DATA SOURCES: EMBASE (1980-3rd quarter of 2003), International Pharmaceutical Abstracts (1970-August 2003), and MEDLINE (1966-August 2003) were searched. Search terms included autism, autistic disorder, citalopram, fluoxetine, fluvoxamine, paroxetine, selective serotonin-reuptake inhibitors, and sertraline. DATA SYNTHESIS: Studies and case reports evaluating treatment outcomes associated with the use of SSRIs in managing impairments of autism were reviewed. Multiple SSRI dosing ranges were evaluated in autistic patients of different ages with various functional impairments. No specific SSRI or dose range has been shown to improve a specific autistic symptom although some patients have demonstrated improvements. CONCLUSIONS: Benefits with SSRIs in treating functional impairments in autism have been observed. Response to therapy and adverse effects are individualized. Current evidence does not support selection of one SSRI over another for any impairment associated with autism.
