Depression is a frequent comorbidity in patients with epilepsy (PWE). However, it is often undertreated because of concerns of seizure exacerbation by antidepressant treatment. The effect of tianeptine on seizure frequency is not known as yet. Thus, we aimed to evaluate the influence of tianeptine on the seizure frequency in PWE. We retrospectively reviewed the medical records of PWE who received tianeptine between January 2006 and June 2013 at the Epilepsy Center of Seoul National University Hospital. Patients were excluded if the dose or type of antiepileptic drugs (AEDs) they took was altered at the start of tianeptine treatment or if the treatment period of tianeptine was <3 months. A total of 74 PWE were enrolled in our study (male: 32, mean age: 41.9±14.5). Sixty-nine patients had localization-related epilepsy, and 5 had idiopathic generalized epilepsy (IGE). Mean seizure frequency during the 3-month period just after tianeptine exposure was compared with the baseline seizure frequency, which showed no change in 69 (93.2%) patients, decrease in 2 (2.7%) patients, and increase in 3 patients (4.1%). The type of epileptic syndrome, the baseline seizure frequency, and the number of coadministered AEDs did not influence the change in seizure frequency after tianeptine prescription. Change in seizure frequency did not differ between the patients given tianeptine as an additive antidepressant and those given tianeptine as a replacement antidepressant. Our data suggest that tianeptine can be prescribed safely to PWE with depression without increasing the seizure frequency regardless of the baseline severity of epilepsy. Tianeptine may be actively considered as a first-choice antidepressant or as an alternative antidepressant in PWE with depression.
