Venlafaxine With or Without Zolpidem in Treating Hot Flashes and Associated Sleep Disorders in Women With Breast Cancer OR at High Risk for Developing Breast Cancer

• Status: Completed
• Trial end date: 2010-03-01
• Target enrollment: 0
• Participant gender: Female

Summary

RATIONALE: Venlafaxine may be effective in relieving hot flashes caused by hormone therapy. Giving venlafaxine with zolpidem (a sleeping pill) may improve sleep and quality of life in women who are receiving hormone therapy for treatment or prevention of breast cancer.

PURPOSE: This randomized clinical trial is studying giving venlafaxine together with zolpidem to see how well it works compared to venlafaxine alone in relieving hot flashes and associated sleep disorders in women who are receiving hormone therapy to treat or prevent breast cancer.
