Dual Effect of Ziconotide in Primary Erythromelalgia

Abstract

Erythromelalgia (EM) is a rare disabling clinical syndrome more commonly known to affect the lower extremities. There is no single effective treatment for this disease that often requires a multidisciplinary approach. Herein, we report the case of a 31-year-old woman affected by primary erythromelalgia who was successfully treated with intrathecal Ziconotide. We also observed an unexpected result following therapy with Ziconotide. The legs and feet of the patient that at the time of admission were swollen and tumefied dramatically improved after one week of the drug administration.
