The maintenance dose is 8 mg once daily in the absence of concomitant antiepileptic drugs that accelerate the metabolism of this product, or 8 to 12 mg once daily in the presence of such concomitant drugs. The dosage may be increased or decreased as necessary by 2 mg at intervals of 1 week or longer depending on symptoms, but the maximum daily dose should not be over 12 mg.
