Seizure Management Guidelines

Acute Seizure Management

The American Academy of Emergency Medicine recommends benzodiazepines as the first-line treatment for acute seizure management, with lorazepam being the preferred benzodiazepine in most emergency protocols 1, 3
Benzodiazepines must be administered immediately for any actively seizing patient, with demonstrated high efficacy in terminating seizures 2
Valproate is effective in controlling seizures in 88% of patients within 20 minutes for status epilepticus, with a dosing regimen of 30 mg/kg IV at 6 mg/kg/hour, followed by maintenance of 1-2 mg/kg/hour 4, 5, 6
Levetiracetam has a 73% response rate in refractory status epilepticus, equivalent to valproate, with a dosing regimen of 30 mg/kg IV at 5 mg/kg per minute (or up to 100 mg/min in pediatrics) 3, 4, 7
Phenytoin has an efficacy of 84% in refractory seizures but carries a 12% risk of hypotension, with a dosing regimen of 20 mg/kg IV (phenytoin equivalents for fosphenytoin) 2, 6

The National Institute for Health and Care Excellence (NICE) recommends carbamazepine as a first-line option for partial onset seizures, with a mechanism of blocking voltage-gated sodium channels 7
Valproate is the definitive first-line treatment recommended by NICE and other guidelines for generalized onset seizures, with a mechanism of multiple actions including sodium channel blockade, GABA enhancement, and T-type calcium channel modulation 1, 7
Lamotrigine and levetiracetam are suitable alternatives to valproate for women of childbearing potential, with lower teratogenic risk 7

The American Academy of Emergency Medicine recommends never using phenobarbitone as first-line treatment, as it performs significantly worse than all other options for treatment withdrawal in both partial and generalized seizures 1
Valproate should not be prescribed to women of childbearing potential without explicit discussion of teratogenic risks and contraceptive measures 7
Monotherapy is preferred to minimize adverse effects and drug interactions, and antiepileptic drugs should not be routinely prescribed after a single unprovoked seizure 7
