Abstract

A step-therapy edit requiring HMO members to use a generic antidepressant, excluding tricyclics, prior to use of a brand-name antidepressant resulted in drug cost savings of 9.0% for the entire class of antidepressants, equal to $1,880,562 ($0.36 PMPM) in 2005 dollars in the first year of the intervention. A small (-1.5%) decrease in use of antidepressants occurred in the intervention group, which was less than the 5.0% decrease in utilization of antidepressants in the comparison group.
