Does dosing sertraline continuously or just before the period work better for severe PMS?
Both dosing schedules worked about equally well, significantly better than placebo.
What they did
Women with severe premenstrual syndrome and impaired functioning were randomly assigned to receive either continuous sertraline, intermittent sertraline just before their period, or placebo for 3 treatment cycles in a double-blind trial. The study was stratified by postmenstrual symptom severity and depression history.
What they found
Both sertraline groups improved significantly more than placebo, with particular improvement in mood and physical symptoms. Improvement occurred swiftly in the first month. Women with higher baseline postmenstrual symptoms remained more symptomatic regardless of treatment. More sertraline-treated women reported improved functioning in family relationships, social activities, and sexual activity.
What it means for you
Sertraline works for severe PMS whether taken daily or only before your period. If you have symptoms after your period ends, the medication may not help as much. The study only lasted 3 months, so longer-term effects are unknown.
