Gabapentin-induced Myoclonus in a Patient with End-stage Renal Disease

ABSTRACT

Myoclonus manifests in a variety of situations including epilepsy, metabolic derangements, brain lesions, and toxicity of drugs. A 57-year-old woman with end-stage renal disease was given gabapentin 900 mg/day for legs' paresthesia. Two days after taking gabapentin, multifocal myoclonus developed involving all extremities. Three days after discontinuation of gabapentin, myoclonus resolved completely. No deterioration of renal function was noted before and after the occurrence of myoclonus. Administration of gabapentin should be performed with caution in patients with impaired renal function.
