What should I watch for?
Tell your doctor or healthcare professional if your symptoms do not start to get better or if they get worse.
Visit your doctor or healthcare professional for regular checks on your progress. Wear a medical ID bracelet or chain, and carry a card that describes your disease and details of your medicine and dosage times.
It is important to take this medicine exactly as directed. When first starting treatment, your dose will need to be adjusted slowly. It may take weeks or months before your dose is stable. You should contact your doctor or healthcare professional if your seizures get worse or if you have any new types of seizures. Do not stop taking this medicine unless instructed by your doctor or healthcare professional. Stopping your medicine suddenly can increase your seizures or their severity.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may interfere with the effect of this medicine.
