Fomepizole is an antidote for ethylene glycol (antifreeze) and methanol intoxication. It inhibits the dehydrogenase enzyme that converts ethylene glycol to toxic metabolites.
Fomepizole is used for treatment of acute ethylene glycol toxicosis in dogs and cats. In people, it is used for this purpose but also is registered for methanol poisoning. It should be used early for maximum success. Fomepizole was safe and effective in dogs in clinical trials if used within 8 hours of poisoning. In cats, it is effective if administered at high doses within 3 hours of ethylene glycol ingestion.
