<qa>  What is the only restriction that no other anti-seizure medications will be givenFollowing randomization, patients will be managed as per the standard labor and delivery protocol for preeclampsia in that institution. The only restrictions will be that no other anti-seizure medications apart from the study agents will be given unless the patient is removed from the study. Use of non seizure-related drugs used will be recorded on the case report. The enrollment of patients in the study will not, other than in the choice of the anti-seizure agent, influence the obstetrical management of the patient. Routine hourly vital signs and fetal heart rate monitoring will be employed. A standardized case report form will be used for all study patients.
