MsFLASH-01: Escitalopram for Menopausal Symptoms in Midlife Women

The MsFLASH-01 study, Efficacy of a Selective Serotonin Reuptake Inhibitor (SSRI) for Menopausal Symptoms in Midlife Women is a randomized, double-blind, placebo-controlled, parallel arm clinical trial. The design includes: 3 weeks of daily recording of hot flashes prior to drug treatment; 8 weeks of double-blind treatment with escitalopram or placebo with dose escalation at 4 weeks among non-responders; 1 week of drug taper for those on higher dose, followed by 2 weeks with no treatment; and a telephone follow-up post-treatment. This study is one of five clinical trials to be conducted as part of the Menopause Strategies - Finding Lasting Answers for Symptoms and Health (MsFLASH) study, a network of investigators and clinical trials designed to find new ways to alleviate the most common, bothersome symptoms of the menopausal transition.
