The efficacy of SSRI use to relieve the symptoms associated with premenstrual dysphoric disorder has been established. We proposed to test the hypothesis that intermittent treatment with paroxetine administered during the luteal phase of the menstrual cycle only is more effective than placebo in improving symptoms of PMDD. This was a double-blind, placebo-controlled, three-arm parallel group study of patients with PMDD. Menstruating women 18 years of age or older who met criteria for inclusion in the study were randomized to one of three arms: paroxetine 10mg/day during the luteal phase of the menstrual cycle; paroxetine 20mg/day during the luteal phase of the menstrual cycle; placebo daily during the luteal phase of the menstrual cycle. The objective was to evaluate the efficacy and safety of intermittent treatment of paroxetine in women with PMDD.
