KEPPRA is a brand name for Levetiracetam, supplied as a tablet. The medicine, its uses, side effects and dosage are the same regardless of brand.
Used for: KEPPRA (levetiracetam) is indicated as adjunctive therapy in the management of adult (> 18 years of age) patients with epilepsy who are not satisfactorily controlled by conventional therapy. 1.1 Pediatrics Pediatrics (< 18 years of age): Based on the data submitted and reviewed by Health Canada, the safety and…

1 Dosing Considerations KEPPRA is given orally with or without food. After oral administration, the bitter taste of levetiracetam may be experienced. 2 Recommended Dose and Dosage Adjustment Adults Treatment should be initiated at a dose of 1000 mg/day, given as twice daily dosing (500 mg bid).
Depending on clinical response and tolerability, the daily dose may be increased every two weeks by increments of 1000 mg, to a maximum recommended daily dose of 3000 mg. In clinical trials, daily doses of 1000 mg, 2000 mg, and 3000 mg, given as twice a day dosing, were shown to be effective.
Although there was a tendency toward greater response rate with higher dose, a consistent statistically significant increase in response with increased dose has not been shown. There are limited safety data from controlled clinical trials at doses higher than 3000 mg/day (approximately 40 patients), therefore these doses are not recommended.
KEPPRA® (levetiracetam) Page 5 of 35 Patients with Impaired Renal Function Renal excretion of unchanged drug accounts for approximately 66% of administered levetiracetam dose. Consistent with this, KEPPRA dosage should be reduced in patients with impaired renal function (see Table 1 below).
Patients with end stage renal disease should receive supplemental doses following dialysis. To use this dosing table, an estimate of the patient’s creatinine clearance is needed. 73 m2) Dosage and Frequency Normal > 80 500 to 1500 mg twice daily Mild 50 – 79 500 to 1000 mg twice daily Moderate 30 – 49 250 to 750 twice daily Severe* < 30 250 to 500 mg twice daily End-stage renal disease patients undergoing dialysis (1) – 500 to 1000 mg once daily (1) Following dialysis, a 250 to 500 mg supplemental dose is recommended.
* or according to best clinical judgment Patients with Impaired Hepatic Function No dose adjustment is needed in patients with mild to moderate hepatic impairment. In patients with severe hepatic impairment, the creatinine clearance may underestimate the renal insufficiency.
73m2. 3 Pediatrics). Geriatrics (≥ 65 years of age) Dose selection and titration should proceed cautiously in elderly patients, as renal function decreases with age. 4 Administration The film-coated tablets must be taken orally, swallowed with liquid.
The daily dose is administered in two equally divided doses. 5 Missed Dose If the patient misses a dose by a few hours, they should be instructed to take KEPPRA as soon as they remember. If it is close to their next dose, they should be instructed to take their medication at the next regular time.
). Seizure Worsening A paradoxical reaction of worsening of seizure may be observed especially when starting treatment or at increase in dose. Lack of efficacy or seizure worsening has also been reported in patients with epilepsy associated with sodium voltage-gated channel alpha subunit 8 (SCN8A) mutations.
In the case of lack of efficacy or worsening seizures, use of KEPPRA should be re-evaluated. Psychiatric Suicidal Ideation and Behaviour Suicidal ideation and behaviour have been reported in patients treated with antiepileptic agents in several indications.
All patients treated with antiepileptic drugs, irrespective of indication, should be monitored for signs of depression and/or suicidal ideation and behaviour and appropriate treatment should be considered. Patients (and caregivers of patients) should be advised to seek medical advice should signs of suicidal ideation or behaviour emerge.
An FDA meta-analysis of randomized placebo-controlled trials, in which antiepileptic drugs were used for various indications, has shown a small increased risk of suicidal ideation and behaviour in patients treated with these drugs.
The mechanism of this risk is not known. There were 43892 patients in the placebo controlled clinical trials that were included in the meta- analysis. Approximately 75% of patients in these clinical trials were treated for indications other than epilepsy and, for the majority of non-epilepsy indications the treatment (antiepileptic drug or placebo) was administered as monotherapy.
, patients in both treatment arms were being treated with one or more antiepileptic drug). 24% for patients on placebo) is based largely on patients that received monotherapy treatment (antiepileptic drug or placebo) for non-epilepsy indications.
The study design does not allow an estimation of the risk of suicidal ideation and behaviour for patients with epilepsy that are taking antiepileptic drugs, due both to this population being the minority in the KEPPRA® (levetiracetam) Page 10 of 35 study, and the drug- placebo comparison in this population being confounded by the presence of adjunct antiepileptic drug treatment in both arms.

Psychiatric Reactions and Changes in Behaviour KEPPRA may cause behavioural abnormalities and psychotic symptoms. Behavioural adverse reactions reported with KEPPRA include affect liability, aggression, agitation, anger, anxiety, apathy, depression, hostility, irritability, personality change, paranoia and obsessive-compulsive disorder (OCD).
Closely monitor patients treated with KEPPRA for psychiatric signs and symptoms. Renal Renal excretion of unchanged drug accounts for approximately 66% of administered levetiracetam dose. 3 Pharmacokinetics, Special Populations and Conditions, Renal Insufficiency).
In patients with renal impairment KEPPRA dosage should be appropriately reduced. e. 2 Recommended Dose and Dosage Adjustment, Patients with Impaired Renal Function).
Reproductive Health:
Female and Male Potential • Fertility The effect of this medication on human fertility is unknown. No adverse effects on male or female fertility or reproductive performance were observed in rats at doses up to 1800 mg/kg/day (see 16 NON-CLINICAL TOXICOLOGY, Reproductive and Developmental Toxicology) • Teratogenic Risk There is non-clinical evidence suggesting that levetiracetam is embryotoxic and teratogenic (see 16 NON-CLINICAL TOXICOLOGY, Reproductive and Developmental Toxicology).
1 Pregnant Women). 1 Pregnant Women Levetiracetam Blood Levels May Decrease During Pregnancy: As with other antiepileptic drugs, physiological changes during pregnancy may affect levetiracetam concentration. There have been reports of decreased levetiracetam concentration during pregnancy.
This decrease is more pronounced during the third trimester (up to 60% of baseline concentration before pregnancy). It is recommended that clinical response should be monitored carefully in women receiving KEPPRA treatment during pregnancy, and determination of changes in plasma concentrations should be considered to ensure that adequate seizure control is maintained throughout pregnancy.
In the event that medication is increased during pregnancy, the dose may need to be adjusted postpartum).
Risk to the Unborn Child:
In reproductive toxicity studies in rats and rabbits, levetiracetam induced developmental toxicity at exposure levels similar to or greater than the human exposure. There was evidence of increased skeletal variations/minor anomalies, retarded growth, embryonic death, and increased pup mortality.
In the rat, fetal abnormalities occurred in the absence of overt maternal toxicity. The systemic exposure at the observed no effect level in the rabbit was about 4 to 5 times the human exposure. KEPPRA® (levetiracetam) Page 11 of 35 There are no adequate and well-controlled studies on the use of levetiracetam in pregnant women.
Levetiracetam and/or its metabolites cross the placental barrier in animal species and in humans. Information about the potential risk for humans is limited. Pregnancy registry data indicate that the risk of […]
