  • Overview

    Lamictal (generic name: lamotrigine) is classified as an anti-epileptic (or anticonvulsant) medication. It is used to treat epileptic seizures in both children and adults, and mood swings in bipolar disorder. Taking Lamictal generally helps people to reduce their seizures. In people with bipolar disorder, Lamictal may help delay or prevent mood swings.

    Lamictal XR (extended release) has been approved for use only in adults and children who are 13 years of age or older.

    Lamictal may be prescribed off-label for additional disorders, such as borderline personality disorder and posttraumatic stress disorder. Such use has not been approved the U.S. Food & Drug Administration.
