Trileptal is a medicine to treat partial seizures in adults. It is taken alone or with other seizure medicines. Taken with other seizure medicines, Trileptal is also used to help treat partial seizures in children 4-16 years old.

Special Warning(s) with Trileptal:

Trileptal can cause low levels of sodium in the blood. Signs of low levels of blood sodium include nausea, extreme drowsiness and discomfort, headache, confusion, or dullness, which can be dangerous. Tell your health care provider if you are taking any other medications that may lower the level of sodium in your blood. Medications that lower sodium include:

carbamazepine (Tegretol®)
chlorpropamide (Diabinese®)
cyclophosphamide
diuretics (water pills)
octreotide
vincristine

Trileptal can cause allergic reactions. If you have had an allergic reaction to other anti-seizure medicines, especially carbamazepine (Tegretol®), tell your health care provider.

Talk to your health care provider before stopping Trileptal or any other seizure medicine. Stopping a seizure medicine all at once can cause status epilepticus, a serious problem.

General Precautions with Trileptal:

Some people taking Trileptal can get serious reactions, including:

• Dizziness
• Drowsiness

• Difficulty with coordination and walking

Trileptal can cause drowsiness. Do not drive a car or operate complex machinery until you know how Trileptal affects you.
