Lamictal (lamotrigine) is an anti-epileptic medication, also called an anticonvulsant. Lamictal is used either alone or in combination with other medications to treat epileptic seizures in adults and children. Lamotrigine is also used to delay mood episodes in adults with bipolar disorder (manic depression). The immediate-release form of Lamictal (regular tablet and orally disintegrating tablet) can be used in children as young as 2 years old when it is given as part of a combination of seizure medications.
