Measure
Treatment Group
The treatment group will be provided with month supply of 30mg tablets of nifedipine extended release prior to discharge from the delivery admission. Dose increases in clinic will be at the discretion of providers, however a treatment algorithm will be provided for guidance.Treatment group will be given a home blood pressure cuff prior to discharge with instructions for use. They will also be scheduled for a 1 week blood pressure check and 4 week postpartum clinic appointment which standard for these patients outside of this proposal. Nifedipine Extended-Release Tablets: Antihypertensive
Control Group
The control group will not receive any medications at discharge. Providers will be instructed to only prescribe new blood pressure medication at subsequent postpartum visits if the blood pressure is in the severe range (\>/=160/110). The control group will be given a home blood pressure cuff prior to discharge with instructions for use. They will also be scheduled for a 1 week blood pressure check and 4 week postpartum clinic appointment which standard for these patients outside of this proposal.
