When someone is diagnosed with epilepsy, one of the first questions is usually: “What is the best treatment for epilepsy?” There is no single treatment that is best for every person. The most effective treatment depends on:
- The type of seizures
- The epilepsy syndrome
- The underlying cause
- Age
- Other medical conditions
- Previous treatment response
- Potential medicine side effects
- Pregnancy or pregnancy planning where relevant
For most people with newly diagnosed epilepsy, an appropriately chosen antiseizure medicine is the first and most effective treatment. The World Health Organization estimates that up to 70% of people with epilepsy could become seizure-free with appropriate diagnosis and antiseizure treatment.
However, if seizures continue after two suitable medicines have been properly tried, the condition may be considered drug-resistant epilepsy. At that point, specialist evaluation for other treatments—including epilepsy surgery—becomes particularly important.
For a broader overview of the condition and available therapies, see our main guide to Epilepsy Treatment.
What Is the Main Goal of Epilepsy Treatment?
The ideal goal is: Complete seizure freedom with as few treatment side effects as possible. Effective treatment also aims to:
- Prevent seizure-related injuries
- Reduce emergency hospital visits
- Improve independence
- Protect education and employment
- Improve sleep and mental wellbeing
- Reduce risks associated with uncontrolled seizures
- Improve overall quality of life

The Best Treatment Starts With Identifying the Seizure Type
Epilepsy is not one single disease. Seizures may be:
- Focal
- Generalised
- Unknown in onset
There are also many specific epilepsy syndromes. This distinction matters because a medicine that works very well for one seizure type may be less effective—or occasionally make another type of seizure worse.
Doctors therefore use information such as:
*AI-generated image - for illustration only. Clinical accuracy is not guaranteed.
- A detailed description or video of the seizures
- Electroencephalography (EEG)
- Brain MRI
- Medical and family history
- Age when seizures began
1. Best Treatment for Focal Epilepsy
Focal seizures begin in one area or network of the brain. They may occur with preserved awareness, impaired awareness, or spread to both sides of the brain and become a bilateral tonic-clonic seizure. Current NICE guidance recommends considering:
- Lamotrigine
- Levetiracetam
2. Best Treatment for Generalised Tonic-Clonic Seizures
Generalised tonic-clonic seizures involve both sides of the brain from the beginning and may cause:
- Loss of consciousness
- Body stiffening
- Rhythmic jerking
Current guidance includes the following first-line options:
- Lamotrigine
- Levetiracetam
- Sodium valproate in appropriate patients
Sodium valproate can be highly effective for some generalised epilepsies, but it has important reproductive safety concerns. It is associated with a substantial risk of birth defects and neurodevelopmental problems when taken during pregnancy.
For this reason, its use is restricted or avoided wherever clinically possible in people who could become pregnant, and regulations vary between countries. Treatment therefore needs to balance seizure control with reproductive safety.
3. Best Treatment for Absence Seizures
Absence seizures commonly cause brief episodes of staring and reduced awareness. If a person has absence seizures without other seizure types, current NICE guidance recommends: Ethosuximide as the first-line treatment. If absence seizures occur alongside other generalised seizure types, treatment may instead involve such as:
- Lamotrigine
- Levetiracetam
- Sodium valproate when appropriate
4. Best Treatment for Myoclonic Seizures
Myoclonic seizures cause brief, shock-like jerks of a muscle or group of muscles. Current guidance includes:
- Levetiracetam
- Sodium valproate in appropriately selected patients
What Is the Best Treatment for Drug-Resistant Epilepsy?
There is no single answer, but treatment options can include:
- Epilepsy surgery
- Additional or newer antiseizure medicines
- Vagus nerve stimulation
- Deep brain stimulation
- Responsive neurostimulation where available
- Ketogenic or related dietary therapy
Epilepsy Surgery: When Can It Be the Best Treatment?
For appropriately selected people with drug-resistant focal epilepsy, surgery may offer a much greater chance of long-term seizure freedom than repeatedly trying additional medicines. Surgery is most successful when doctors can identify a specific area of the brain that:
*AI-generated image - for illustration only. Clinical accuracy is not guaranteed.
- Consistently produces the seizures
- Can be treated without causing unacceptable neurological problems
Examples of operations include:
- Temporal lobe resection
- Lesionectomy
- Other focal resections
- Disconnection surgery in selected severe epilepsy syndromes
How Successful Is Epilepsy Surgery?
Outcomes vary greatly according to the type and location of epilepsy. Temporal lobe epilepsy is one of the best-studied examples. A large systematic review involving more than 30,000 surgical patients found that approximately 69% of adults undergoing temporal lobe epilepsy surgery achieved an Engel Class I or equivalent outcome, meaning freedom from disabling seizures.
This number should not be applied to all epilepsy surgery. Outcomes depend on:
- Where seizures begin
- MRI findings
- The underlying brain abnormality
- How completely the seizure-producing area can be treated
- Other individual factors
Vagus Nerve Stimulation
Vagus nerve stimulation (VNS) uses a small implanted device that sends electrical impulses through the vagus nerve in the neck. It is generally considered when:
*AI-generated image - for illustration only. Clinical accuracy is not guaranteed.
- Epilepsy remains drug resistant
- Resective surgery is not suitable
- Or surgery has not provided sufficient seizure control
Deep Brain Stimulation and Responsive Neurostimulation
Other neuromodulation options include:
Deep Brain Stimulation (DBS)
DBS uses implanted electrodes to deliver electrical stimulation to specific brain networks involved in seizures.
Responsive Neurostimulation (RNS)
RNS monitors brain activity and delivers stimulation when abnormal electrical patterns associated with seizures are detected. These options may help selected people with drug-resistant epilepsy when complete surgical removal of the seizure-producing tissue is not possible.
How Doctors Match the Best Treatment to the Patient
| Clinical Situation | Possible Treatment Direction |
|---|---|
| Newly diagnosed focal epilepsy | Appropriate antiseizure medicine such as lamotrigine or levetiracetam |
| Generalised tonic-clonic seizures | Lamotrigine, levetiracetam or carefully selected valproate treatment |
| Pure absence seizures | Ethosuximide commonly used first-line |
| Myoclonic seizures | Levetiracetam or appropriately selected valproate treatment |
| Failure of one medicine | Review diagnosis and treatment, then try another suitable monotherapy or add-on treatment |
| Failure of two appropriate medicines | Evaluate for drug-resistant epilepsy and refer to a tertiary epilepsy service |
| Drug-resistant focal epilepsy with removable seizure focus | Epilepsy surgery may offer the best chance of seizure freedom |
| Drug-resistant epilepsy not suitable for resection | Neuromodulation such as VNS, DBS or RNS may be considered |
| Selected drug-resistant epilepsy | Ketogenic or related dietary therapy may be considered |
Common Epilepsy Treatment Mistakes to Avoid
- Stopping antiseizure medication suddenly
- Missing doses regularly
- Choosing medication without confirming the seizure type
- Assuming every seizure medicine works for every type of epilepsy
- Ignoring significant medication side effects
- Continuing repeated medication trials for years after drug-resistant epilepsy is established without considering specialist evaluation
- Using supplements or alternative therapies instead of effective epilepsy treatment
The Bottom Line
There is no single best treatment for epilepsy because epilepsy includes many different seizure types, syndromes and underlying causes. For most people, the best starting treatment is a correctly selected antiseizure medicine. Lamotrigine and levetiracetam are commonly used first-line treatments for focal epilepsy.
Up to 70% of people with epilepsy may become seizure-free with appropriate diagnosis and antiseizure treatment. However, if two adequately tried and appropriately selected medications fail to produce sustained seizure freedom, epilepsy is considered drug resistant under the International League Against Epilepsy definition.
At that point, the next step should not simply be endless medication changes. Patients should be evaluated at a specialist epilepsy centre to determine whether epilepsy surgery, neuromodulation or specialist dietary therapy may provide better control. For selected patients with drug-resistant focal epilepsy—particularly temporal lobe epilepsy—surgery can offer one of the highest chances of long-term seizure freedom.
Most importantly: The best epilepsy treatment is the treatment matched correctly to the person's seizure type, underlying cause and individual circumstances—and changed promptly when it is clear that the current strategy is not providing adequate seizure control.
