Keppra XR is a prescription used to treat certain types of seizures, including partial-onset seizures, in patients who are 12 years old or older. It is an extended-release form of the antiepileptic medication Levetiracetam. Levetiracetam is in a class of medications called anticonvulsants. It works by decreasing abnormal excitement in the brain.

Levetiracetam is also used in combination with other medications to treat seizures in adults and children 12 years of age or older with juvenile myoclonic epilepsy. It gradually releases the medication over a longer period, which helps to maintain consistent levels in the body and reduce the frequency of seizures.

Use and Dosage

Keppra XR (Levetiracetam) comes as an extended-release tablet that should be taken orally once a day as prescribed by your doctor, with or without food. The tablet should be swallowed whole and should not be crushed or chewed to avoid releasing all the drug at once, which can increase the risk of side effects.

The appropriate dosage of Keppra XR depends on factors such as your medical condition and how you respond to treatment. Children's dosage is typically calculated based on weight. To minimize the risk of side effects, your physician may initially prescribe a low dose of this medication, gradually increasing it over time. Be sure to follow your doctor's instructions closely.

Take Keppra XR regularly to derive the maximum benefit from it. To help you remember, take it at the same time every day. Do not take more than the prescribed dose or use this medication more frequently or for a longer duration than recommended. Following such practices will not hasten your recovery and could increase your chances of experiencing unpleasant side effects.

Do not abruptly stop taking Keppra XR without first consulting your doctor. If you stop the medication without tapering it off, your seizures could potentially worsen. Your doctor will advise you on gradually reducing your dosage.
