Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
This research is investigating severe premenstrual symptoms—a condition that causes significant mood and physical changes in the weeks before a period. The study will test whether sertraline, a commonly used antidepressant, at a low dose can help reduce these symptoms when taken only during the second half of the menstrual cycle. Researchers will also study changes in brain chemistry across the menstrual cycle to understand why some women are more sensitive to hormone fluctuations.
Severe premenstrual symptoms affect millions of women but scientists don't fully understand the underlying cause or why the medication works in some people. This study aims to fill that gap by examining the brain's chemistry and how this treatment affects it.

If you have severe premenstrual symptoms, you would track your mood and symptoms across two menstrual cycles while providing eight blood samples—four in each cycle. During the second cycle, you would take either a daily 50 mg pill of the medication or a placebo from ovulation until your period starts. If you are a healthy control (no premenstrual symptoms), you would track your mood, provide four blood samples, and answer surveys about your menstrual cycle and mood. All visits involve blood work and mood tracking questionnaires.
