Abstract

Gabapentin, an anti-epileptic drug (AED) is commonly used off label for management of neuropathic pain and psychiatric disorders. Dosing of gabapentin requires taking into consideration the renal function as it is entirely cleared by the kidneys. Acute kidney injury and end stage renal disease increase the risk of developing myoclonic activity, an infrequent manifestation of gabapentin toxicity. We report a case of confusion and myoclonic activity related to gabapentin toxicity coincident with acute kidney injury that resolved with discontinuation of gabapentin and treatment with intravenous fluid hydration. As gabapentin is commonly used off label across multiple specialties, clinician recognition of the significance of renal dosing and understanding of the potential association with myoclonus and neurotoxicity is important.
