A Case of Gabapentin-induced Myoclonus in a Type 2 Diabetic Patient with End-stage Renal Disease / 임상당뇨병

ABSTRACT

Development of myoclonus can manifest as a side effect of antiepileptic drugs in subjects with preexisting epilepsy, post-traumatic brain injury, encephalopathy, or focal and multifocal brain lesions. A 69-year-old male showed new onset severe myoclonus and confusion two days after taking 1200 mg gabapentin. The patient had end-stage renal disease secondary to type 2 diabetes and was receiving hemodialysis twice a week. After increasing hemodialysis to three times a week and discontinuing gabapentin, myoclonus spontaneously resolved. Here we report the first case of myoclonus in a Korean subject with diabetic renal failure. We recommend caution in the administration of gabapentin for diabetic subjects with renal disease.
