If your blood pressure is consistently higher than 150/100 during pregnancy or if you have high levels of protein in your urine or other evidence that your kidneys aren't functioning properly, you may be at high risk for serious complications of hypertension, including stroke. You may require medication (for example, hydralazine-sold under the brand name Apresoline) to lower your blood pressure and protect you against complications. If your blood pressure is over 180/120-dangerously high-you may require intravenous medication to bring your blood pressure down immediately.
