Summary
This study tested whether a 14-day course of hydrochlorothiazide (a water pill) could prevent high blood pressure from returning after delivery in women with preeclampsia or gestational hypertension. Over 450 women were planned, but the trial was stopped early. The main goals were to see if the drug reduced hospital readmissions or the need for extra blood pressure medication.
