OverviewTOP

Levetiracetam is used to help control certain types of seizures in the treatment of epilepsy. This medicine cannot cure epilepsy and will only work to control seizures for as long as you continue to use it.

This medicine is available only with your doctor's prescription.

Proper UseTOP

Take this medicine only as directed by your doctor, to help your condition as much as possible. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. Also, do not change your dose without checking first with your doctor.

This medicine comes with a Medication Guide. Read and follow the instructions carefully. Ask your doctor if you have any questions.

Levetiracetam may be taken with or without food or on a full or empty stomach. However, if your doctor tells you to take the medicine a certain way, take it exactly as directed. You should try to take this medicine at the same time each day.

Swallow the tablet or the extended-release tablet whole. Do not break, crush, or chew it. There is an oral liquid form of this medicine if you or your child cannot swallow the tablets.

If you are using the Spritam® tablet or the Spritam® tablet for suspension, make sure your hands are dry before you handle the tablet. Do not open the blister pack that contains the tablet until you are ready to take it. Remove the tablet from the blister pack by peeling back the foil, then taking the tablet out. Do not push the tablet through the foil. Place the tablet on your tongue and take a sip of water. After it has melted, swallow.

You may also add one whole Spritam® tablet for suspension to a small volume of liquid in a cup (1 tablespoon or enough to cover the medicine), and swirl gently. Swallow right away after it has dissolved. Then add a small volume of liquid to cup again, swirl gently, and swallow the liquid.

Measure the oral liquid with a marked measuring spoon, dropper, oral syringe, or medicine cup. The average household teaspoon may not hold the right amount of liquid. If you have any questions about this, ask your doctor or pharmacist.

This medicine can be used with other seizure medicines. Keep using all of your seizure medicines unless your doctor tells you to stop.

Take only the form of this medicine that your doctor prescribed. If you refill your prescription and your pills look different, do not take the medicine and tell your doctor or pharmacist right away.
