The other alcohols. Methanol, ethylene glycol, and isopropanol.

The alcoholic patient, in an attempt to maintain an altered mental status, may ingest ethanol substitutes containing methanol, ethylene glycol, or isopropanol. The subsequent clinical presentation in the Emergency Department is highly variable and depends on the ethanol substitute ingested, the time since ingestion, and concomitant ethanol abuse. This article describes the clinical features of intoxication by the ethanol substitutes. Early diagnosis and therapeutic intervention may prevent irreversible sequelae. The rationale for treatment interventions is discussed.
