Inclusion criteria

* 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

Exclusion criteria

* 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
