Neuropathic pain due to metastatic invasive cancer successfully treated with intravenous lidocaine hydrochloride after failure of oral pregabalin

The concomitant administration of adjuvant analgesics is recommended for neuropathic pain due to metastatic invasive cancer, because such pain may respond poorly to analgesic agents such as non-opioid analgesics and opioids. We report the case of a 44-year-old female patient with severe pain caused by a lumbosacral plexus injury associated with a failure of oral pregabalin（ 200 mg daily for 2 weeks）. We administered lidocaine hydrochloride（ drip infusion 960 mg/day）, which successfully relieved the pain.
