This randomized controlled trial compares two common medications, labetalol and extended-release nifedipine, to determine which is more effective at managing postpartum high blood pressure. We hypothesize that extended-release nifedipine will better control blood pressure and reduce the need for continued medication beyond six weeks postpartum. The study will enroll 110 postpartum participants, randomly assigning them to one of the two medications, with remote blood pressure monitoring to evaluate treatment effectiveness and inform postpartum hypertension management.
