Randomised trial, 1998

Does taking sertraline only during the second half of the cycle help PMDD symptoms?

Yes, in this small study sertraline taken only during the luteal phase (the time between ovulation and your period) worked better than placebo at easing PMDD symptoms, but the evidence is weak because so few women finished the study.

Early or limited evidence 31 women with PMDD enrolled; 11 completed the full study

What they did

Researchers ran a randomized, double-blind, placebo-controlled crossover trial in 31 women with PMDD. The study lasted 7 months: 2 months of screening, 2 months of either placebo or sertraline (taken only in the luteal phase), 1 month off treatment, then 2 more months switching to the other treatment. Women tracked symptoms daily. Only 11 women completed the whole study.

What they found

During the luteal phase, women had higher (worse) symptom scores on placebo cycles than on sertraline cycles, for both behavioral symptoms (p = .0052) and physical symptoms (p = .014).

What it means for you

This suggests sertraline can work for PMDD even when taken only part of the month, which could mean less medication overall. The big limitation is that only 11 of 31 women finished the study, so the results come from a very small group.
