Generic Name: Oxcarbazepine
Trileptal (Tri-LEP-tal) is related to Tegretol, TegretolXR, Carbatrol, and Epitol (carbamazepine). It was developed in an effort to combine the effectiveness of these related drugs with fewer side effects and drug interactions. Trileptal was approved for use in the treatment of epilepsy in 2000. It is used as single drug therapy (monotherapy) and as add-on therapy (adjunctive) in adults and children 4 years of age and older with partial seizures. It tends to be better tolerated than carbamazepine with fewer side effects.
It is available in tablet and liquid suspension forms. At doses above 1200 mg/day Trileptal may increase phenytoin (Dilantin) levels. Phenobarbital, phenytoin and carbamazepine may decrease blood levels of the active metabolite of Trileptal. It may also reduce the effectiveness of oral contraceptives.
Common side effects include fatigue, headache, dizziness, sleepiness, unsteadiness, nausea, vomiting and double vision. Allergic rashes sometimes develop, but less frequently than with carbamazepine.
