Bupropion (BPP) was originally an antidepressant, but now it is also used for seasonal affective disorder and smoking cessation. The aim of this systematic review was to evaluate the clinical epidemiological profile, pathological mechanisms, and management of BPP-associated movement disorders. Relevant reports in six databases were identified and assessed by two reviewers without language restriction. A total of 63 reports of 710 cases from 16 countries were assessed. The movement disorders associated with BPP found clearly defined were: dyskinesia (8), dystonia (7), parkinsonism (7), myoclonus (6), tic (6), stuttering (3), rapid eye movement sleep disorders (2), and ballism (1); the not clearly defined cases included 488 tremors, 80 slurred speech, 48 ataxia, 20 abnormal movements, 19 falls, 4 akathisia, 3 dyskinesia, 2 hyperkinesia, 2 poor coordination, and the rest was only reported once (dystonia, myoclonus, motor tic, and rigidity). The mean age was 46 years (7–85 years). The male was predominant sex (52.77%). The mean BPP dose was 248.38 mg, and the most common indication was a major depressive disorder (73.68%). The average time of onset was 3.47 weeks and of recovery was 2.71 weeks. The most common management was BPP withdrawal. In the literature, the majority of the cases did not clearly report the clinical neurological examination and lacked electrodiagnostic studies. Future studies about adverse effects with BPP should describe at least the clinical characteristics and the physical exam of the individuals, especially when fall and slurred speech are observed.
