- Recently, a study was published which compared adverse drug events in patients who had received either fomepizole or ethanol for ethylene glycol or methanol poisoning.
- Importantly, this is the first trial which has compared these events head to head.
- Retrospectively, 172 charts over a 9 year period were reviewed. Toxicologists identified at least 1 ADR in 74 of 130 ethanol treated cases (57%) versus 5 of 42 fomepizole treated cases (12%).
- Severe ADRs occurred in 20% of ethanol treated patients vs 5% fomepizole treated patients.
- This adds further data to support the use of choosing fomepizole over alcohol for treatment of toxic alcohol poisonings
