Reversible, late-onset disulfiram-induced neuropathy and encephalopathy.

Disulfiram toxicity is a well-recognized cause of peripheral neuropathy and encephalopathy, usually developing within a few months of the start of therapy. We describe a patient who insidiously developed a peripheral neuropathy and encephalopathy after thirty years of disulfiram ingestion. Both complications partially resolved after the medication was stopped.
