Some benzodiazepines can help treat seizures, but they work in a different way than levetiracetam ER (Keppra XR) to calm brain activity.

But it can stay in your system longer if you have kidney problems or are older in age. This is because the kidneys help remove the medication from the system. If the kidneys don't work as well (like with kidney issues or older age), the medication can stay in the body longer. Ask your prescriber for more information about how long levetiracetam ER (Keppra XR) stays in your system.

Keppra and Keppra XR are both seizure medications with the same active ingredient, levetiracetam. The key differences are how often you take them and what types of seizures they treat. Keppra is an immediate-release tablet that's taken twice a day. Keppra XR is the extended-release version that's taken once a day. Both treat focal aware (partial-onset) seizures. But Keppra is also an add-on treatment for juvenile myoclonic epilepsy and generalized tonic-clonic seizures. Ask your prescriber to learn more about the differences between Keppra and Keppra XR.
