Gabapentin has been accepted worldwide as a novel antiepileptic drug with a favourable tolerability profile. Although its exact mode of action is not known, it is recently widely used to manage symptomatic treatment of neuropathic pain syndromes. It has few side effect profiles and it is known not to be associated with liver injury. But we experienced a case of liver injury associated with gabapentin. A 44-year-old man was hospitalized because of seizure caused by septic shock. He complained of tingling sensation and burning pain on his both legs. Gabapentin was prescribed to control his symptoms. An increase of serum aminotransferases was detected after gabapentin therapy, and immediately after stopping it, aminotransferase level normalized. (J Korean Acad Rehab Med 2006; 30: 286-288)
