In status epilepticus, the priority is rapid seizure stopping followed by preventing recurrence. The best approach is to give an IV benzodiazepine to halt the current seizure quickly, then give a loading dose of an IV anticonvulsant like fosphenytoin to achieve therapeutic levels and provide ongoing control. IV benzodiazepines act fast by enhancing GABA-A receptor activity, which suppresses seizure activity almost immediately. Because benzodiazepines wear off relatively quickly, a loading dose of fosphenytoin is used right after to maintain seizure suppression and reduce the chance of rebound activity as the benzodiazepine wears off. Fosphenytoin is chosen because it can be given IV, reaches therapeutic levels promptly, and has a longer duration of action than the benzodiazepine, helping stabilize the patient during acute management.

Options that rely on oral benzodiazepine, or that skip anticonvulsants entirely, or that depend only on observation, don’t provide the urgent, rapid control or sustained suppression required in this emergency situation.
