The purpose of the present study was to describe the use of psychopharmacological drugs for the treatment of a stated or presumed psychiatric comorbid condition in patients with refractory epilepsy and discuss the clinical implications of such treatment. The study was a retrospective descriptive study in patients admitted to the National Center for Epilepsy in Norway based on medication described in medical records. The mean age was 40 years (range: 9-90), and the gender ratio was 56/44% female/male. Psychotropic drugs (antidepressants and antipsychotics) were used to a lower extent than in the general population in Norway. Drugs for ADHD were predominantly used in children. The prevalence of patients treated with psychiatric comedication was 13% (143 of 1139 patients). The patients used two to eight concomitant CNS-active drugs, which calls for the close monitoring of potential pharmacodynamic and pharmacokinetic interactions and should challenge clinicians to achieve a less complex pharmacotherapy. Psychiatric comorbidity is an important concern in patients with refractory epilepsy and may be undertreated.
