In mild preeclampsia, antihypertensive drugs may mask disease progression
In severe disease, expectant management is warranted only between 23 and 32 weeks, and only if mother and fetus are stable

Once you decide to expectantly manage a patient with preeclampsia, the balancing act begins. That means weighing fetal benefits against maternal risks, since the only justification for expectant management is to prolong pregnancy for fetal gain—there is no advantage to the mother.
The best approach is to classify the woman’s preeclampsia by the degree of severity and gestational age at the time of diagnosis, then follow recommendations tailored to that particular category.
