Depression-related costs include a relatively large share of indirect costs
. We describe the impact of antidepressant treatment on absenteeism among w
orkers diagnosed and treated for depression, Monthly absenteeism counts fro
m employers were summed in the 6 months before and after the initiation of
antidepressant therapy in 630 workers treated for depression with a tricycl
ic antidepressant or a selective serotonin reuptake inhibitor (fluoxetine s
ertraline, paroxetine). Monthly mean absenteeism was compared using pairwis
e t tests. Absenteeism increased before antidepressant initiation and decre
ased after the treatment began for all antidepressant cohorts. Absenteeism
in the selective serotonin. reuptake inhibitor cohorts decreased at similar
rates for 4 months but was higher in the paroxetine cohort in months five
and six after the treatment initiation. Our data suggest that alternative t
reatments ts for depression may have differential impact on indirect costs,
but further research is warranted.
