AbstractA 42-year-old man was brought to the emergency department with ethylene glycol intoxication. He was hemodynamically stable and had normal renal function. His serum ethylene glycol concentration was 284 mg/dl approximately 1 hour after ethylene glycol consumption. The patient was treated with fomepizole and forced diuresis. Elimination of ethylene glycol in this patient followed first-order pharmacokinetics. Elimination pharmacokinetics in this patient were compared with that in a patient who received fomepizole and hemodialysis. Fomepizole monotherapy can be given in patients without renal failure or metabolic acidosis even with serum ethylene glycol concentrations greater than 50 mg/dl. However, cost estimates based on this case suggest that if the patient is treated adequately with a single hemodialysis session and 24-hour hospitalization, then fomepizole monotherapy may be more expensive than the combination regimen of fomepizole and hemodialysis.
