Fomepizole as an adjunct in acetylcysteine treated acetaminophen overdose patients: a case series.

This case series has demonstrated the safety of fomepizole in high-risk APAP overdose. The efficacy of fomepizole needs to be further elucidated through controlled clinical trials on a larger scale. In massive APAP overdoses, fomepizole should be considered as an adjunct due to the known failure rate of NAC and the safety profile of fomepizole.
