Answer

Ethanol competes for alcohol dehydrogenase and can be used as an alternative to fomepizole. It is administered orally or intravenously to saturate alcohol dehydrogenase, to which it has a higher affinity, thus inhibiting metabolism of methanol or ethylene glycol to its toxic metabolites. The blood ethanol level should be maintained at 100-150 mg/dL.
