Keppra is an anti-epileptic drug, also called an anticonvulsant.

Keppra is a prescription medicine used to treat certain types of seizures in people with epilepsy, including partial onset seizures, myoclonic seizures, and tonic-clonic seizures.

When used for partial onset seizures:

• Keppra XR is for adults and children at least 12 years old.

• Keppra (immediate release tablets or oral solution) may be used in children as young as 1 month old.

Keppra is also used with other seizure medications to treat tonic-clonic seizures in people who are at least 6 years old, and myoclonic seizures in people at least 12 years old.

Keppra injection is used only as an alternative for patients when oral use is temporarily not possible.

Do not stop using Keppra without first talking to your doctor, even if you feel fine. You may have increased seizures if you stop using this medicine suddenly. You may need to use less and less before you stop the medication completely.

Some people have thoughts about suicide when first taking this medicine. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.

Wear a medical alert tag or carry an ID card stating that you take Keppra. Any medical care provider who treats you should know that you take seizure medication.

Keppra may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert. Tell your doctor if you are pregnant or plan to become pregnant while using this medication. Do not start or stop taking levetiracetam during pregnancy without your doctor's advice. Having a seizure during pregnancy could harm both the mother and the baby. Seizure control is very important during pregnancy and the benefits of preventing seizures may outweigh any risks posed by using this medicine.
