RATIONALE: Duloxetine hydrochloride may lessen muscle, bone, and joint pain caused by
hormone therapy. It is not yet known whether duloxetine hydrochloride is more effective than
a placebo in treating patients with muscle, bone, and joint pain caused by hormone therapy.
PURPOSE: This randomized phase III trial studies how well duloxetine hydrochloride works
compared to a placebo in treating muscle, bone, and joint pain in patients with early-stage
breast cancer receiving hormone therapy.
