What is the primary treatment for status epilepticus?

• A. High-dose corticosteroids
• B. Benzodiazepines, such as lorazepam, followed by anti-seizure medications.
• C. Antipsychotics
• D. Diuretics

Answer: (B)

When someone is in status epilepticus, stopping the seizure quickly is the top priority to prevent brain injury from hypoxia and metabolic stress. The best initial pharmacologic move is a benzodiazepine given as soon as possible—usually IV lorazepam—because these drugs rapidly enhance inhibitory GABA transmission in the brain, halting seizure activity within minutes. Lorazepam is often preferred because it has a strong, durable CNS effect, though any benzodiazepine given promptly can work. If IV access isn’t available, intramuscular midazolam or rectal diazepam are appropriate alternatives. Because benzodiazepines mainly terminate the current seizure but don’t provide lasting control, after the seizure is stopped you proceed with a second-line antiseizure medication (such as phenytoin or fosphenytoin, valproate, or levetiracetam) to prevent recurrence and address ongoing epileptiform activity. In cases where seizures persist despite those measures, additional therapies and closer ICU management may be needed. Other options listed aren’t aimed at rapidly stopping seizures—corticosteroids are used for other brain conditions, antipsychotics do not treat seizures, and diuretics don’t address neuronal hyperexcitability.
