Gabapentin for Epilepsy

Examples

Generic NameBrand Name
gabapentinGralise, Neurontin

How It Works

It is not known exactly how gabapentin prevents seizures.

Why It Is Used

Gabapentin may be used alone or combined with other antiepileptic medicines to control partial seizures in adults and in children ages 3 and older.

How Well It Works

People taking gabapentin alone and in addition to other antiepileptic medicines may have fewer seizures.1

Side Effects

Gabapentin is a well-tolerated drug that usually causes only mild side effects. These often go away in 1 to 2 weeks and include:

  • Dizziness.
  • Drowsiness and fatigue.
  • Headache.
  • Weight gain.
  • Foot swelling.

FDA Advisory. The U.S. Food and Drug Administration (FDA) has issued an advisory on antiepileptic drugs (AEDs) and the risk of suicide. Talk to your doctor about these possible side effects and the warning signs of suicide in adults and in children and teens.

See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)

What To Think About

It may take time and careful, controlled adjustments by you and your doctor to find the combination, schedule, and dosing of medicine to best manage your epilepsy. The goal is to prevent seizures while causing as few side effects as possible. After you and your doctor figure out the medicine program that works best for you, make sure to follow your program exactly as prescribed.

  • Drug interactions. Many medicines for epilepsy can interact with other medicines you are taking. This means that your epilepsy medicine may not work as well, or it may affect the way another medicine you are taking works. Some of these interactions can be dangerous. It is important to tell your doctor about all the medicines, herbal pills, and dietary supplements you are taking. Gabapentin may be a good choice if you are taking medicines for other conditions, because it does not interact with many other medicines.
  • Risk of birth defects. All medicines for epilepsy have some risk of birth defects. But the risk of birth defects needs to be carefully compared to other risks to the baby if the mother stops taking her epilepsy medicine. If you are thinking about becoming pregnant, be sure to plan ahead and talk with your doctor about the benefits and risks of taking epilepsy medicine during your pregnancy. It you are already pregnant, it is not too late. The best thing to do is talk to your doctor about your pregnancy before you make any changes to the medicines you are taking.
  • Other concerns. For some people, gabapentin may produce side effects or carry risks that are not fully known yet. Report any unexpected side effects or problems to your doctor.
