AES 2016 — Evidence-Based Guideline: Treatment of Convulsive Status Epilepticus in Children and Adults

First-line: IV lorazepam, IV diazepam, or IM midazolam (Level A). Second-line if seizures continue: IV fosphenytoin/phenytoin (Level A), valproic acid (Level C), or levetiracetam (evidence indeterminate). The guideline does not address treatment of refractory status epilepticus beyond this point.
