Implications for Patient Care
Fomepizole is an antidote labeled to treat known or suspected ethylene glycol or methanol intoxication. Fomepizole may be used alone or in combination with hemodialysis.2, 6,7
Fomepizole therapy alone does not replace the need for supportive fluid and electrolyte therapy to address metabolic acidosis.6, 7
Alternative Agents & Management
- Consult a poison center (1-800-222-1222) or medical toxicologist for any patient with a suspected ethylene glycol or methanol intoxication.
- Ethanol is an alternative to fomepizole. Oral ethanol may be preferred to an extemporaneous intravenous preparation due to potential delays in preparation.7 Commercial intravenous ethanol in dextrose solutions are no longer marketed.7
- Consultation with a poison center or medical toxicologist is essential when using ethanol as an antidote. Ethanol must be dosed according to patient specific criteria such as past tolerance and requires significant laboratory monitoring.7
