Brief summary
This study will evaluate the long-term safety of LAMICTAL(lamotrigine)in subjects with partial seizures previously enrolled in protocol LAM20006 and in subjects 1-24 months of age who have never received LAMICTAL(LAMICTAL-naive). For LAMICTAL-naive subjects, LAMICTAL will be added to the subject's current epilepsy medications.

Eligibility
Inclusion criteria
* Must have completed the Open-Label Phase of protocol LAM20006 or meet criteria for LAMICTAL naive subjects as follows: * A confident diagnosis of epilepsy. * 4 or more partial seizures per month. * current treatment with 1 or 2 anti-epileptic drugs.
Exclusion criteria
* Has seizures not related to epilepsy. * Has a surgically implanted and functioning vagal nerve stimulator. * Has previously been treated with lamotrigine. * Is currently taking felbamate, ACTH (adrenocorticotrophic hormone) or is on the ketogenic diet. * Use of experimental medication within 30 days of enrollment.
