Management of Uncontrolled Seizures on Levetiracetam

Second-Line Options for Refractory Seizures

• Valproate has shown 68% seizure cessation rates in status epilepticus studies, comparable to levetiracetam, according to the American College of Emergency Physicians 1
• Phenobarbital can be used as a loading dose of 10-20 mg/kg IV if seizures persist despite optimized levetiracetam, as recommended by the National Institute of Clinical Excellence 2, 3
• Phenytoin is a traditional second-line agent, though levetiracetam has fewer drug interactions, as noted by the American Academy of Neurology 1

Safety Profile at Higher Doses

• Psychiatric symptoms, such as irritability and behavioral changes, can occur when escalating levetiracetam doses, and patients should be screened for suicidal ideation, according to the American Psychiatric Association 4

Common Pitfalls to Avoid

• Levetiracetam should not be abruptly discontinued without a taper plan, as this risks breakthrough seizures, as advised by the American Academy of Neurology 4
• Therapeutic drug monitoring of levetiracetam is not recommended due to lack of correlation between serum levels and efficacy, as stated by the National Institute of Clinical Excellence 5
