Keppra XR (levetiracetam) Extended-Release Tablets is an anti-epileptic drug used to treat partial onset seizures in adults and children who are at least 4 years old, and is also used to treat tonic-clonic seizures in adults and children who are at least 6 years old, and myoclonic seizures in adults and children who are at least 12 years old. Keppra XR is available in generic form. Common side effects of Keppra XR include drowsiness, dizziness, weakness, tired feeling, loss of appetite, or stuffy nose. Effects are more common during the first 4 weeks and usually lessen as your body adjusts to Keppra XR.

The starting dose of Keppra XR is 1000 mg once daily. The daily dosage may be adjusted in increments of 1000 mg every 2 weeks to a maximum daily dose of 3000 mg. Other drugs may interact with Keppra XR. Tell your doctor all prescription and over-the-counter medications and supplements you use. During pregnancy, Keppra XR should be used only when prescribed. It may harm a fetus. Since untreated seizures are a serious condition that can harm both a pregnant woman and her fetus, do not stop taking this medication unless directed by your doctor. If you are planning pregnancy, become pregnant, or think you may be pregnant, talk to your doctor about using this medication during pregnancy. This medication passes into breast milk. Consult your doctor before breast-feeding.

Keppra XR FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

The following adverse reactions are discussed in more details in other sections of labeling:

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

KEPPRA XR Tablets

In the controlled clinical study in patients with partial onset seizures, the most common adverse reactions in patients receiving KEPPRA XR in combination with other AEDs, for events with rates greater than placebo, were irritability and somnolence.

Table 3 lists adverse reactions that occurred in at least 5% of epilepsy patients receiving KEPPRA XR in the placebo-controlled study and were numerically more common than in patients treated with placebo. In this study, either KEPPRA XR or placebo was added to concurrent AED therapy.

Table 3: Adverse Reactions in the Placebo-Controlled, Add-On Study in Patients Experiencing Partial Onset Seizures

  KEPPRA XR
(N=77) %
Placebo
(N=79) %
Influenza 8 4
Somnolence 8 3
Irritability 7 0
Nasopharyngitis 7 5
Dizziness 5 3
Nausea 5 3

Discontinuation Or Dose Reduction In The KEPPRA XR Controlled Clinical Study

In the controlled clinical study, 5% of patients receiving KEPPRA XR and 3% receiving placebo discontinued as a result of an adverse reaction. The adverse reactions that resulted in discontinuation and that occurred more frequently in KEPPRA XR-treated patients than in placebo-treated patients were asthenia, epilepsy, mouth ulceration, rash, and respiratory failure. Each of these adverse reactions led to discontinuation in a KEPPRA XR-treated patient and no placebo-treated patients.

Immediate-Release KEPPRA Tablets

Table 4 lists the adverse reactions in the controlled studies of immediate-release KEPPRA tablets in adult patients experiencing partial onset seizures. Although the pattern of adverse reactions in the KEPPRA XR study seems somewhat different from that seen in partial onset seizure controlled studies for immediate-release KEPPRA tablets, this is possibly due to the much smaller number of patients in this study compared to the immediate-release tablet studies. The adverse reactions for KEPPRA XR are expected to be similar to those seen with immediate-release KEPPRA tablets.

Adults

In controlled clinical studies of immediate-release KEPPRA tablets as adjunctive therapy to other AEDs in adults with partial onset seizures, the most common adverse reactions, for events with rates greater than placebo, were somnolence, asthenia, infection, and dizziness.

Table 4 lists adverse reactions that occurred in at least 1% of adult epilepsy patients receiving immediate-release KEPPRA tablets in placebo-controlled studies and were numerically more common than in patients treated with placebo. In these studies, either immediate-release KEPPRA tablets or placebo was added to concurrent AED therapy.

Pediatric Patients 4 Years To < 16 Years

In a pooled analysis of two controlled pediatric clinical studies in children 4 to 16 years of age with partial onset seizures, the adverse reactions most frequently reported with the use of immediate-release KEPPRA in combination with other AEDs, and with greater frequency than in patients on placebo, were fatigue, aggression, nasal congestion, decreased appetite, and irritability.

Table 5 lists adverse reactions that occurred in at least 2% of pediatric patients treated with immediate-release KEPPRA and were more common than in pediatric patients on placebo. In these studies, either immediate-release KEPPRA or placebo was added to concurrent AED therapy. Adverse reactions were usually mild to moderate in intensity.

In controlled pediatric clinical studies in patients 4-16 years of age, 7% of patients treated with immediate-release KEPPRA tablets and 9% of patients on placebo discontinued as a result of an adverse event. In addition, the following adverse reactions were seen in other controlled studies of immediate-release KEPPRA tablets: balance disorder, disturbance in attention, eczema, hyperkinesia, memory impairment, myalgia, personality disorders, pruritus, and blurred vision.

Comparison Of Gender, Age And Race

There are insufficient data for KEPPRA XR to support a statement regarding the distribution of adverse reactions by gender, age, and race.

Postmarketing Experience

The following adverse reactions have been identified during postapproval use of immediate-release KEPPRA tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

The listing is alphabetized: abnormal liver function test, choreoathetosis, drug reaction with eosinophilia and systemic symptoms (DRESS), dyskinesia, erythema multiforme, hepatic failure, hepatitis, hyponatremia, muscular weakness, pancreatitis, pancytopenia (with bone marrow suppression identified in some of these cases), panic attack, thrombocytopenia, and weight loss. Alopecia has been reported with immediate-release KEPPRA use; recovery was observed in majority of cases where immediate-release KEPPRA was discontinued.
