Randomised trial, 1987

Does progesterone suppository help premenstrual syndrome?

No, progesterone vaginal suppositories (200 mg) did not reduce PMS symptoms more than placebo. This was a small study of 30 women.

Moderate study design 30 women with premenstrual syndrome

What they did

30 women with PMS took progesterone vaginal suppositories (200 mg) during one cycle and placebo during another cycle in a double-blind study. Researchers compared physical, psychological, and behavioral symptoms between the progesterone and placebo cycles.

What they found

There were no significant differences in physical, psychological, or behavioral symptoms when progesterone cycles were compared with placebo or baseline cycles.

What it means for you

Progesterone suppositories don't appear to work better than placebo for PMS. This was one of the first controlled studies of progesterone treatment, challenging earlier uncontrolled studies that suggested it helped. The study was small, so more research is needed.
