From the Research
Pregnant patients with chronic hypertension who are taking labetalol should measure their blood pressure before taking their medication. This timing provides the most accurate assessment of how well their hypertension is being controlled between doses. Taking blood pressure measurements at the same time each day, preferably in the morning before the first dose of labetalol, establishes a consistent baseline for monitoring. Additionally, patients should occasionally measure their blood pressure at different times of the day to ensure adequate 24-hour control. When measuring, patients should rest seated for 5 minutes first, use a properly calibrated device, and take two readings about 1 minute apart. This approach helps healthcare providers make appropriate adjustments to medication dosing. If blood pressure readings are consistently high before the next scheduled dose, it may indicate that the current dosing regimen needs adjustment to provide better control throughout the day. Proper blood pressure control during pregnancy is essential to reduce risks of complications for both mother and baby, including preeclampsia, placental abruption, and fetal growth restriction. According to the most recent study 1, there were no significant differences in predetermined maternal or neonatal outcomes detected on the basis of the use of labetalol or nifedipine for treatment of chronic hypertension in pregnancy, which supports the use of labetalol as a viable option for managing chronic hypertension in pregnant patients.
Some key points to consider when measuring blood pressure in pregnant patients with chronic hypertension include:
- Using a properly calibrated device to ensure accurate readings
- Taking two readings about 1 minute apart to account for any variability
- Resting seated for 5 minutes before taking measurements to ensure a stable baseline
- Measuring blood pressure at the same time each day, preferably in the morning before the first dose of labetalol
- Occasionally measuring blood pressure at different times of the day to ensure adequate 24-hour control
By following these guidelines and prioritizing blood pressure control, healthcare providers can help reduce the risks of complications associated with chronic hypertension in pregnancy, as supported by studies such as 2, 3, and 1.
