Pregabalin for postherpetic itch: a case report

Abstract

Abstract Background Postherpetic itch has not commonly received attention as a complication of herpes zoster because pain predominates over itch in most patients with herpes zoster. Most cases of postherpetic itch are mild; however, cases of severe postherpetic itch reducing quality of life are rare. Case presentation A 52-year-old woman complained of severe itch in her left pinna and cheek 1 month after the first onset of herpes zoster at the same site. Owing to her scratching, she developed ulcers on her left pinna and cheek. Pregabalin was prescribed, and the itch subsided immediately, with the ulcers disappearing within 1 month. Discussion Severe itch was thought to be caused by neural injury from herpes zoster. Pregabalin may be a useful treatment option for neuropathic itch induced by herpes zoster.
