Is this trial a fit for you?

Likely a good fit

Ideal candidates are menstruating individuals aged 18-35 who experience painful periods and have regular menstrual cycles.

Probably not a fit

Patients with active pelvic or abdominal malignancies, other chronic pain conditions, or those on continuous hormonal medication may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the effectiveness of naproxen sodium, a nonsteroidal anti-inflammatory drug (NSAID), in treating menstrual pain and preventing chronic pelvic pain in menstruating adults aged 18-35 with painful periods. Participants will take either naproxen sodium or a placebo during their menstrual periods for one year and will complete questionnaires and hormone tests at home. The study aims to determine if the reduction in menstrual pain can predict the reduction in non-menstrual pelvic pain and if those with the greatest sensitivity reduction will experience the most significant pain relief.

Why it matters

Potential benefit: If successful, this study could provide a new approach to managing menstrual pain and preventing chronic pelvic pain in young women.

How similar studies have gone: Other studies have shown positive outcomes with NSAIDs for menstrual pain, suggesting this approach may be effective.
