Focal Epilepsy: Structured Add-on Treatment When Second-line Therapy Has Been Unsuccessful
When patients with focal epilepsy do not achieve adequate seizure control despite second-line add-on antiseizure treatment, a further escalation step is indicated. The choice of agent at this stage is guided by the patient's prior treatment history and individual factors.
Treatment Approach at This Stage
For focal seizures that remain uncontrolled after second-line add-on therapy, evidence-based third-line add-on antiseizure options exist. If the initial choice at this stage is not effective, an alternative agent from the same category can be considered next. The complete structured regimen — specifying which agents to evaluate and the decision sequence — is available in the full protocol.
