• > **Dilution Required**: Concentrated drug must be diluted as directed before intravenous administration to prevent severe vein irritation. * **Timing**: Efficacy drops significantly if given after 8 hours in dogs, or after 3 hours in cats. If azotemia is present, prognosis is poor. * **Supportive Care**: Fomepizole must be used alongside aggressive fluid therapy and correction of acid-base/electrolyte imbalances. * **Decontamination**: If the patient presents within 1-2 hours of ingestion, consider inducing emesis or performing gastric lavage with activated charcoal to minimize absorption. * **Pregnancy**: FDA Category C. Benefits generally outweigh risks in life-threatening toxicity.
