Adults

• Monotherapy

Adults and adolescents from 16 years of age
The recommended starting dose is 250 mg twice daily which should be increased to an initial therapeutic dose of 500 mg twice daily after two weeks. The dose can be further increased by 250 mg twice daily every two weeks depending upon the clinical response. The maximum dose is 1500 mg twice daily.

• Add-on therapy

Adults (≥18 years) and adolescents (12 to 17 years) of 50 kg or more
The initial therapeutic dose is 500mg twice daily. This dose can be started on the first day of treatment.

Depending upon the clinical response and tolerance, the daily dose can be increased up to 1,500mg twice daily. Dose changes can be made in 500mg twice daily increases or decreases every two to four weeks.

Children
The physician should prescribe the most appropriate pharmaceutical form and strength according to age, weight and dose.

The safety and efficacy of levetiracetam concentrate for solution for infusion in children less than 4 years have not been established.

Monotherapy
The safety and efficacy of levetiracetam in children and adolescents below 16 years as monotherapy treatment have not been established.

There are no data available.

Add-on Therapy for Children (4 to 11 years) and Adolescents (12 to 17 years) weighing less than 50 kg
The initial therapeutic dose is 10 mg/kg twice daily.

Depending upon the clinical response and tolerability, the dose can be increased up to 30 mg/kg twice daily. Dose changes should not exceed increases or decreases of 10 mg/kg twice daily every two weeks. The lowest effective dose should be used.

Dose in children 50 kg or greater is the same as in adults.

Dose recommendations for children and adolescents:

Infants and children less than 4 years
There are insufficient data to recommend the use of levetiracetam in children under 4 years of age.

Elderly
Adjustment of the dose is recommended in elderly patients with compromised renal function.

Renal impairment
The daily dose must be individualised according to renal function (see section Warnings and Precautions – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information). For adult patients, refer to the following table and adjust the dose as indicated. To use this dosing table, an estimate of the patient’s creatinine clearance (CLcr) in mL/min is needed. The CLcr in mL/min may be estimated from serum creatinine(mg/dl) determination, for adults and adolescents weighing 50 kg or more, using the following formula:

Then CL_cr is adjusted for body surface area (BSA) as follows:

Dosing adjustment for adult and adolescent patients weighing more than 50 kg with impaired renal function

For children with renal impairment, levetiracetam dose needs to be adjusted based on the renal function as levetiracetam clearance is related to renal function. This recommendation is based on a study in adult renally-impaired patients.

Hepatic impairment
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. Therefore, a 50% reduction of the daily maintenance dose is recommended when the creatinine clearance is <60 mL/min/1.73m² (see section Warnings and Precautions – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).
