Could a safer drug replace magnesium for seizure prevention in pregnancy?
NCT ID NCT07220902
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether levetiracetam, a seizure medication, works as well as magnesium sulfate to prevent seizures in pregnant people with severe preeclampsia. About 1,240 participants at 32 weeks or more will be randomly assigned to one of the two drugs. The goal is to see if levetiracetam can prevent seizures with fewer side effects for both mother and baby.
