Epilepsy Home > How Does Lamictal Work?

It is not known exactly how Lamictal® (lamotrigine) works for treating epilepsy. However, studies suggest that the drug may work by affecting sodium channels in the brain, thereby preventing the abnormal activity from spreading to other areas. This action helps control seizures.
Exactly how Lamictal works to treat bipolar disorder is also unclear. Clinical studies have shown that people taking the drug went longer without having an episode of mania or depression, compared to those not taking it. This effect may also be explained by the drug's effect on sodium channels.
