Get StartedPrecautions
It is important that your doctor check your progress at regular visits. This is necessary to allow dose adjustments and to test for serious unwanted effects.
Do not stop taking felbamate without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping completely. Stopping the medicine suddenly may cause your seizures to return or to occur more often.
Felbamate may cause blurred vision, double vision, or other changes in vision. It may also cause some people to become dizzy or drowsy. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert or able to see well. If these reactions are especially bothersome, check with your doctor.
