Myoclonic Seizures in Adults: What to Do When Antiepileptic Monotherapy Has Not Achieved Seizure Freedom
This protocol applies to adults aged 16 years and older with progressive myoclonic epilepsy who continue to experience myoclonic seizures despite treatment with a single antiepileptic drug.
Clinical Scenario
The patient is an adult (16 years of age or older) with progressive myoclonic epilepsy, with myoclonic seizures as the presenting seizure type. The therapeutic goal is freedom from seizures.
Previous Line — Failure Condition
First-line management consisted of monotherapy with an indicated antiepileptic drug, individualised to the patient. Escalation to this protocol is triggered when that single-drug regimen has failed to achieve the primary target: freedom from seizures.
Next-Step Treatment Approach
When monotherapy has not achieved seizure freedom, the indicated next step involves a combination approach — moving beyond a single agent to a regimen that incorporates more than one antiepileptic drug.
The specific agents, selection criteria, and full regimen are contained in the structured protocol below.
