Rafsanjan University of Medical Sciences, Rafsanjan, Iran. *Corresponding author. E-mail: Reza_Bidaki@yahoo.com, Reza_Bidaki222@gmail.com. Tel: +03915230584. Topiramate is an antiepileptic drug and uses to induce weight loss. We introduce a case of Topiramate
induced Dissociative disorder with non common presentation. The patient was 27 year old obese girl.
Because of depressed mood, increased sleep and slow psychomotor she was treated with Sertraline
(Zoloft®, Pfizer, United states of America) 50mg and Bupropion 75 mg/daily. The patient had
complained strongly of hyperphagia and overweight. So Topiramate 25 mg/daily was started and was
increased to 50 mg/daily. The patient experienced a feeling of great strength and ability to perform
every task by her right hand, sense of depersonalization and derealization and feelings of all levels to
the steeper slopes and slightly angled. About one day after discontinuation of Topiramate, symptoms
had been eliminated and did not repeat any more in two months follow up. Our patient had Sertraline
(Zoloft®) 50 mg and Bupropion 75 mg/daily as two contributing factor when Topiramate started. The
increased serotonin level can be a justification for patient’s symptoms but alteration of the
norepinephrine system is one other mechanism. Physicians should be aware of this interaction and do
not prescribe these drugs simultaneously. More studies are suggested to find the exact mechanism for
these symptoms.

Key words: Topiramate, dissociative disorder, weight loss, sertraline, bupropion.

INTRODUCTION

Topiramate is an antiepileptic drug that use in
is defined as an experience of individual feeling unreality management of epilepsy and migraine prophylaxis.
