About half of all people who have one unprovoked seizure never have another.
Most people who have epilepsy can avoid seizures if they get enough sleep and take prescribed medications as directed. Most people with epilepsy need to take medication indefinitely. Never stop medication without specific instructions from your physician.
If you have had only a couple of seizures and have a normal EEG, your doctor might reevaluate the need for medication if you have no seizures after two to five years.
