NCT00137709

Brief Summary

Both sodium valproate and lamotrigine are currently used in the treatment of newly diagnosed epilepsy. Although they appear to have similar efficacy, they have different side effects, which have not been well studied. This study aims to compare one particular aspect of their possible side effects, namely whether they affect certain hormonal functions.
