Seizure activity and safety in combined treatment with venlafaxine and ECT: A pilot study

Some authors have described the combined use of ECT and psychotropic drugs, emphasizing possible interactions and synergisms of this combined therapy. We are unaware of reports of the concurrent use of the new antidepressant venlafaxine with ECT. The goals of our study were to assess the possible ef fects of venlafaxine on seizure length during ECT and the possible cardiova scular effects of this combined treatment. Nine severely ill, depressed pat ients were treated simultaneously with bilateral ECT and venlafaxine 150 mg /day and were compared with nine control, depressed subjects taking tricycl ic antidepressants (TCA) and ECT. No patients had prolonged seizures and no spontaneous/tardive seizures outside ECT were observed. With regard to mea n seizure length, no statistically significant differences were observed be tween the control group and the venlafaxine group. Neither significant incr eases in arterial blood pressure nor electrocardiographic recording abnorma lities were found in venlafaxine patients when compared with the tricyclic group. Even though the small number of patients used is a significant limit ation of this study, we found that combined venlafaxine and ECT appears to be safe when used in depression.
