In children, Trileptal has been used primarily to treat partial seizures, ones that begin in a limited area of the brain.

Doctors figure out how much medicine to give to young children based mostly on their weight. To keep side effects at a minimum, the doctor probably will prescribe a low dose to start with and increase it slowly. Children usually start with a dose of 8 to 10 milligrams (mg) for each kilogram (kg, about 2.2 pounds) of their body weight per day in two divided doses.

After a gradual increase every two weeks or so, most children do best taking about 10 to 50 mg per kg per day, split into two doses, Adjusted for weight, this is a little higher than the adult dose because children's bodies eliminate Trileptal more quickly.

If the liquid suspension is used, it is very important to shake the bottle thoroughly immediately before measuring. A child who gets a dose from a bottle that has not just been well shaken may get too much or too little medication.
