SSRIs for premenstrual dysphoric disorder.

Around 2-10% of women have premenstrual symptoms that severely disrupt daily living.

Fluoxetine, a selective serotonin re-uptake inhibitor (SSRI), is licensed in the UK for the treatment of PMDD. Here, we discuss the diagnosis of PMDD and the evidence for the efficacy of fluoxetine and other SSRIs in its treatment.
