Non-randomised trial, 1996 # Does fluvoxamine help premenstrual dysphoric disorder? In this open-label study, fluvoxamine at 100 mg per day improved PMDD symptoms in 60% of women, with the biggest improvements in irritability, anxiety, and feeling out of control. Side effects were mostly mild and temporary. Early or limited evidence 10 women with PMDD (12 initially screened) ## What they did Researchers conducted an open-label trial where women took fluvoxamine (an antidepressant medication) daily for 2 menstrual cycles. The dose was gradually increased to 100 mg per day. Women tracked their symptoms daily. ## What they found At 4 weeks, mean premenstrual symptom scores improved significantly, and improvement continued at 8 weeks. The biggest improvements were in irritability, anxiety, feeling out of control, and decreased interest in activities. 60% (6 of 10) of women had at least 50% reduction in symptoms. Side effects included insomnia (6 women), fatigue (4), dry mouth (4), and nausea (3), and were generally mild and temporary. ## What it means for you Fluvoxamine may help PMDD symptoms, with most benefits for mood and anxiety. This is an open-label pilot study with only 10 women and no control group, so we cannot be certain of the effect without a larger controlled trial. The side effects were generally mild. 10 Women completing treatment 60% With 50% or greater symptom improvement 100 mg/day Final dose ## About the study Original title Fluvoxamine for premenstrual dysphoric disorder: a pilot study Authors Freeman EW, Rickels K, Sondheimer SJ Journal The Journal of clinical psychiatry Year 1996 Study design Non-randomised trial Participants 6 What was tested Fluvoxamine (antidepressant) at 85-100 mg per day for 2 menstrual cycles Read the paper [https://pubmed.ncbi.nlm.nih.gov/8698682/](https://pubmed.ncbi.nlm.nih.gov/8698682/) ## Topics [Premenstrual syndrome (PMS)](https://niyora.com/research/topics/condition-pms/)[Premenstrual dysphoric disorder (PMDD)](https://niyora.com/research/topics/condition-pmdd/)[Low mood and depression](https://niyora.com/research/topics/symptom-depression-mood/)[Sleep and insomnia](https://niyora.com/research/topics/symptom-sleep/)[Fatigue and energy](https://niyora.com/research/topics/symptom-fatigue/)[SSRIs and antidepressants](https://niyora.com/research/topics/treatment-ssri/)[Major depressive disorder](https://niyora.com/research/topics/comorbidity-major-depression/) Research tells you what helps on average.
