Premenstrual physical and mood symptoms are common among reproductive-age women, but diagnostic criteria and treatment strategies to recognize premenstrual disorders are not always clearly understood. The purpose of this document to examine the evidence for commonly used approaches in the treatment of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD). Until recently, the difficulty in managing PMS / PMDD was largely attributed to imprecise diagnostic criteria, poorly designed clinical trials, and promotion of treatment options for which there was no scientific support. In the mid-1980s, however, rigorous criteria for the diagnosis of PMS / PMDD were defined. Since then, most studies of pathophysiology and treatment have met recognized standards of scientific design. Selective serotonin reuptake inhibitors (SSRIs) are found to be effective in treating PMS / PMDD symptoms and many other treatment options are discussed.
