Evaluation of the Efficacy of Fomepizole in the Treatment of Acetaminophen Overdose

If randomized to Control, the participant will receive only N-acetylcysteine. The dose will be determined by the site investigator. Typical continued infusion rate is 6.25 mg/kg/hr. The control drug (D5W) will be administered using the same schedule as fomepizole.

If randomized to fomepizole, the proposed infusion schedule for fomepizole closely mirrors the dosing outlined in the medication's package insert. Specifically, the Antizol (fomepizole) doses (bags) #1-5 allocated for the study will precisely adhere to the manufacturer's recommendations from the package insert. This entails an initial loading dose of 15 mg/kg followed by four subsequent doses of 10 mg/kg. The dose of fomepizole will not be adjusted based on age, presence of liver injury or renal insufficiency.
