Crossover from polytherapy to monotherapy in primary generalized epilepsy.
Patients with primary generalized tonic-clonic seizures can obtain equal or superior seizure control and fewer side effects when managed with valproate than when taking multiple antiepileptic drugs. The conversion from polytherapy to valproate monotherapy must be done carefully if side effects and seizure exacerbation are to be avoided. A gradual crossover, often requiring several months, is usually necessary. A well-developed plan and understanding by the patient, coupled with close follow-up, are essential. The major improvement in quality of life that results for the majority of patients after completing such a conversion fully warrants the extra time and effort required.
