Written informed consent, dated and signed by the subject or, when needed, by (preferably both) parents or legal guardian (not applicable at the study site in Innsbruck).
Male or female children, adolescents and adults having completed the final visit of the double-blind study N166, the final visit of the double-blind study N01057, the second-year evaluation visit of the open follow-up study N164 or the final visit of the open follow-up study N129 (at the study site in Innsbruck only adults will be included).
The final visit of the previous study and entry into the present study will ideally occur on the same day.
Subjects who were/are suffering from primary generalized (type II) epileptic seizures, according to the Guidelines of the International League Against Epilepsy (ILAE). (6.)
Subjects for whom the Investigator believes a reasonable benefit (efficacy or tolerability) from the long-term administration of LEV may be expected.
Female subjects must be premenarcheal, two years postmenopausal or surgically sterile (bilateral oophorectomy or tubal ligation, complete hysterectomy) or using a medically accepted contraceptive method (intrauterine device, barrier method plus spermicide, oral contraceptive at a stable dose for one menstrual cycle prior to the start of the study, contraceptive implant inserted at least one month prior to the start of the study, or contraception injection administered one month prior to the start of the study). Abstinence will be considered as an acceptable method of contraception on a case-by-case basis upon discussion with UCB Pharma or its representative. The subject must understand the consequences and potential risks of inadequately protected sexual activity, be educated about and understand the proper use of contraceptive methods, and undertake to inform the Investigator of any potential change in status.
Subjects must be considered as reliable and capable of adhering to the protocol, according to the judgement of the investigator.

Clinically significant deviations from reference range values for laboratory parameters, as determined by the Investigator.
Receipt of any drug with possible central nervous system effects unless at a stable dose.
Receipt of any drug (other than hormonal treatment and the subject.s normal AED(s)) 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.
History in prior levetiracetam study of poor compliance with visit schedule or medication intake.
