Colchicine-induced myopathy and neuropathy.

Abstract

Myopathy and neuropathy that have been induced by colchicine have been described only occasionally, although colchicine is a widely used drug. We describe a case of colchicine-induced myopathy and neuropathy in an 84-year-old woman who had renal impairment. Results from a muscle biopsy showed characteristic vacuolar myopathy and autophagic vacuoles. The cessation of medication resulted in a marked improvement of myopathy.
