Clinical Question

In patients with a history of epilepsy, how long must one be seizure-free before stopping antiepileptic drug therapy?

Evidence-Based Answer

Children with epilepsy should be seizure-free for at least two years before stopping antiepileptic drug therapy, especially those who have partial seizures or a history of abnormal electroencephalography (EEG) results. Evidence is insufficient to guide this decision for children with generalized seizures, and there is no evidence with which to answer this question for adults. (Strength of Recommendation: B, based on inconsistent or limited-quality patient-oriented evidence.)

Practice Pointers

Patients sometimes present to their family physician requesting discontinuation of their seizure medication, yet doing so prematurely can be harmful. A detailed history is important to establish whether seizures were focal (partial) or generalized (involving bilateral hemispheres of the brain), and whether consciousness was impaired. Attempts should be made to retrieve EEG or imaging study results. Furthermore, some patients may have had nonepileptic (psychogenic) seizures or seizures provoked by a resolved stimulus (e.g., fever, alcohol or drug withdrawal).1
