Brief Summary
The goal of this study is to compare levetiracetam to magnesium sulfate for the prevention of eclamptic seizures in pregnant persons with severe preeclampsia that are 32 or more weeks pregnant. This is an equivalence study so our primary goal is to see no difference in the incidence of seizure in the two groups. Since side effects can be a significant problem with magnesium sulfate and these patients are at significant risk of life threatening complications, we also plan to evaluate several secondary outcomes in the mothers and the babies, including: severe allergic reaction, magnesium toxicity, ICU admission, hospital readmission, transfusion for any reason, pulmonary edema, cardiomyopathy, Posterior Reversible Encephalopathy Syndrome, eclamptic seizure, loss of vision, stroke, renal injury requiring dialysis, cardiac arrest, maternal death, unexpected stillbirth or neonatal death, NICU admission, Apgars and length of neonatal respiratory support.

Outcome Measures
Primary Outcomes (1)
Eclamptic Seizure
Seizure based on clinical diagnosis by managing physician. It will be considered and eclamptic seizure for purposes of the study if it occurs following enrollment in the study.
From enrollment until then end of monitoring at 6 weeks postpartum.
Study Arms (2)
Levetiracetam Arm
EXPERIMENTALThis experimental arm will receive oral levetiracetam 3 times daily after an initial loading oral dose.
Magnesium Sulfate Arm
ACTIVE COMPARATORThis arm will receive standard treatment- a loading dose of magnesium sulfate followed by a continuous infusion that is the current standard of care (4 gram bolus followed by 2grams per hour continuous infusion).
Interventions
1g oral loading dose followed by 300mg q 8 hours beginning 8 hours after loading dose.
Eligibility Criteria
You may qualify if:
- Pregnant or postpartum women aged 19 years or older
- Diagnosed with preeclampsia with severe features, superimposed preeclampsia or HELLP syndrome
- At risk for eclampsia and eligible for seizure prophylaxis
- Less than 2 hours exposure to magnesium sulfate or greater than 48 hours since last dose.
- Admitted or plan to proceed with delivery
You may not qualify if:
- \<32 weeks estimated gestational age
- History of epilepsy or seizure disorders unrelated to pregnancy
- Allergy or contraindication to Levetiracetam or Magnesium Sulfate
- Severe renal impairment (Oliguria \<120ml in 4 hours)
