Seizure and Epilepsy Treatment Guidelines

Introduction to Treatment

The American Academy of Neurology recommends monotherapy with standard antiepileptic drugs (carbamazepine, phenobarbital, phenytoin, or valproic acid) as first-line treatment for epilepsy, with drug selection based on seizure type, patient characteristics, and side effect profiles 1, 2

Clinical diagnosis of epilepsy can be made based on detailed seizure history from patients and witnesses, and non-specialist healthcare providers can be trained to recognize and diagnose convulsive epilepsy 1, 2, 4

For acute seizure management without IV access, rectal diazepam should be administered, and IM phenobarbital can be considered when rectal diazepam is not possible 2, 4
With IV access, IV benzodiazepine (lorazepam preferred over diazepam) should be administered for acute seizure management 2
For refractory status epilepticus, IV valproate (30 mg/kg) or levetiracetam (30 mg/kg) can be considered if seizures continue after benzodiazepines and phenytoin 3, 5
Valproate and levetiracetam show similar efficacy (68-73%) in refractory status epilepticus 5

Carbamazepine is preferred for partial onset seizures, with an initial dose of 200 mg twice daily for adults and children >12 years 2, 6
Valproic acid is the preferred first-line treatment for generalized seizures, but should be avoided in women of childbearing potential 2, 6
Monotherapy is preferred over polytherapy to minimize side effects 2, 6
AEDs should not be prescribed after a first unprovoked seizure unless there is a high risk for recurrence 2, 6
Consider discontinuation of AEDs after 2 seizure-free years, taking into account clinical, social, and personal factors 2, 6

For status epilepticus, IV benzodiazepines followed by phenytoin/fosphenytoin, valproate, or levetiracetam should be administered 3, 7
For febrile seizures, follow local standards for fever management, observe for 24 hours, and consider prophylactic intermittent diazepam only for recurrent or prolonged complex febrile seizures 2, 4

Polytherapy should be avoided when possible to minimize adverse effects and drug interactions 2, 6
