Systematic review, 2022

Is taking antidepressants only at certain times as effective as taking them every day for PMS?

Yes. Intermittent dosing works just as well as taking them every day, with effects starting within hours and peaking within 2 days.

Strong study design Women with premenstrual symptoms (across 8 studies)

What they did

Systematic review and meta-analysis of randomized trials comparing intermittent versus continuous dosing of SSRIs (a type of antidepressant) for premenstrual symptoms.

What they found

Eight studies were reviewed. Intermittent dosing was as effective as continuous dosing. Response begins within hours and peaks in 2 days. The studies used sertraline and citalopram at low to standard doses.

What it means for you

Women can take these antidepressants only when needed rather than every day, which may reduce side effects and the stigma of daily medication use.
