Case ReportsA 55-year-old woman presented with numbness and pain in both lower extremities. The pain was of sudden onset and of 4 months' duration. A nerve conduction study demonstrated a bilateral sensorimotor peripheral neuropathy with axonal and demyelinating features of a mild degree. Initial treatment with oral thiamine and topiramate had little efficacy and caused unacceptable side effects. A switch to 1500 mg bid levetiracetam plus nortriptyline resulted in a 60% improvement in pain symptoms. A 75-year-old man presented with numbness in both feet of 5 years' duration. The sensation of numbness had progressed to persistent pain, resulting in sleep disruption. The patient's use of oral thiamine did not lead to pain relief, but the addition of 500 mg levetiracetam once in the evening led to a complete resolution of his pain and to sleep improvement. A 67-year-old obese male was referred from a podiatrist with progressive dysfunction in both lower extremities that developed over a 1-year period. Walking more than a few steps resulted in sharp, shooting pain that at night disrupted sleep. A nerve conduction study demonstrated a severe bilateral sensorimotor peripheral neuropathy with axonal and demyelinating features. Treatment with 1000 mg levetiracetam bid resulted in complete absence of pain.ConclusionsIn these 3 case studies, levetiracetam was demonstrated to be an effective therapy in the treatment of neuropathic pain. It has the benefits of a low incidence of adverse events and an improvement in patients' sleep.
