A Case Of Pregabalin-Induced Parkinsonism

Drug-induced parkinsonism is the second common movement disorder after Parkinson's disease. It occurs due to the use of not only neuroleptics but also some other medications as pregabalin. Pregabalin is an antiepileptic drug and a structural analog of gamma-aminobutyric acid (GABA), and its use decreases the release of several neurotransmitters. In this case report, we present a 53-year-old female patient with the signs of parkinsonism following pregabalin treatment. Drug-induced parkinsonism was diagnosed based on the clinical features, investigations, and resolution of the complaints. The symptoms relieved after the treatment stopped at a follow-up of 10 days. Due to the rare report of pregabalin-induced parkinsonism, we aim to enhance clinicians' awareness of pregabalin's probable side effects.
