It has also been shown to help to stabilize mood in mood disorders.

ADULTS

Lamotrigine combined with Tegretol Dilantin Phenobarbital and Mysoline:

One 50-milligram dose per day for 2 weeks then two 50-milligram doses per day for 2 weeks. The usual maintenance dose is 300 to 500mg (in two divided doses) is reached by increasing the daily dose by 100mg per day over 1 to 2 weeks.

The dosage of Lamotrigine varies significantly depending on the other medications that you may be taking. It should be started at low doses and slowly increased over time in all cases to prevent side effects such as a severe rash.

CHILDREN

Lamotrigine can be added to other epilepsy drugs prescribed for children under 16 who have a serious form of epilepsy known as Lennox-Gastaut syndrome. Doses for children under 12 are based on the child’s weight. Children 12 to 16 receive the adult dose. Doses are increased gradually from a low starting level to limit the risk of severe rash. Lamotrigine is not used as a replacement drug for children under 16.
