 Women recruited to the study will be randomly assigned to one of two groups: self-management or usual care. Participants allocated to usual care will have their BP monitored and medication adjusted by their general practitioner GP and midwife as normal. Participants allocated to the self-management group will use a home BP monitor daily following discharge from hospital after birth. They will be provided with an individualised schedule for gradually decreasing their medications in line with their BP readings. Women will be followed up for 6 months.
