Related Articles Minor Increase in Risk of Road Traffic Accidents After Prescriptions of Antidepressants: A Study of Population Registry Data in Norway. J Clin Psychiatry. 2008 Jun 3;:e1-e5 Authors: Bramness JG, Skurtveit S, Neutel CI, Mørland J, Engeland A OBJECTIVES: Experimental studies have shown that both depression and the use of antidepressants may impair the ability to drive a motor vehicle. Population-based studies have been inconclusive. Differences in results have been shown for cyclic, sedating antide-pressants and newer, nonsedating antidepressants. The objective of the present study was to examine whether the use of antidepressants by drivers increased the risk of being involved in traffic accidents. METHOD: From April 2004 to September 2006, information on prescriptions, road accidents, and emigrations/deaths was obtained from 3 Norwegian population-based registries. Data on people between the ages 18-69 (N = 3.1 million) were linked. Exposure consisted of receiving prescriptions for any anti-depressants. Standardized incidence ratios (SIRs) were calculated by comparing the incidence of accidents during time exposed with the incidence over the time not exposed. Sedating antidepressants (tricyclic antidepressants, mianserin, and mirtazapine) were studied together as one group, and newer, nonsedating antidepressants (selective serotonin reuptake inhibitors, moclobemide, venlafaxine, and reboxetine) as another. RESULTS: Dur ...
