OBJECTIVE: To review the available literature regarding the use of melatonin in the treatment of tardive dyskinesia (TD).
DATA SOURCES: Literature was identified through MEDLINE (1966September 2002), PsycINFO (1967September 2002), and references of relevant articles. Review articles, case reports/series, and animal and human studies were reviewed.
DATA SYNTHESIS: Melatonin has been investigated in TD based on its antioxidant properties. Animal studies and several human case series describe an association between melatonin and TD. Two recent, controlled studies evaluated the role of melatonin in the treatment of TD.
CONCLUSIONS: There is a paucity of data evaluating the use of melatonin in TD. Both of the controlled studies evaluating its use are limited by methodologic issues. Although the most recent trial did report a statistically significant improvement in TD with melatonin, these results are not considered to be clinically significant. There are inadequate data at the present time to support the use of melatonin in patients with TD.
Key Words: melatonin, tardive dyskinesia
