Eligibility Criteria

Age4 Years - 64 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Male or female children, adolescents and adults having completed the final visit of a previous study with levetiracetam (LEV)
  • Subjects who were/are suffering from primary generalized (type II) epileptic seizures
  • Subjects for whom the Investigator believes a reasonable benefit (efficacy or tolerability) from the long-term administration of LEV may be expected

You may not qualify if:

  • Known clinically significant acute or chronic illness, for example: cardiac, renal or hepatic dysfunction, etc., which may impair reliable participation in the trial or necessitate the use of medication not allowed by protocol
  • Concomitant use of any drug with possible central nervous system effects unless at a stable dose
  • Concomitant use of any drug (other than hormonal treatment and the subject's normal anti-epileptic drugs (AEDs) that may influence the metabolism of the concomitant AED(s), except if the dose has been stable before entry in the study for sufficient length of time
