Methodology · worked example, guidelines & full notes
Supportive care and decontamination come before the antidote.
When to use
Rapid bedside reference for the targeted antidote. For life-threatening cases, prioritise airway/breathing/circulation, decontamination and a poison-control consult.
How it works
Examples: NAC for acetaminophen; naloxone for opioids; atropine + pralidoxime for organophosphates; fomepizole for toxic alcohols; hydroxocobalamin for cyanide.
Key points
- Supportive care and decontamination come before the antidote.
- Methylene blue and rasburicase are cautioned/contraindicated in G6PD deficiency.
- Long-acting toxins often outlast the antidote — repeat or infuse.
- Doses must be individualised to the toxin, amount and levels.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Toxin | Methanol/ethylene glycol |
|---|
→AntidoteFomepizole (or ethanol) + dialysis
- Fomepizole:15 mg/kg load → 10 mg/kg q12h
- Adjuncts:Haemodialysis; folate for methanol, thiamine/pyridoxine for ethylene glycol
| Toxin | Acetaminophen |
|---|
→AntidoteNAC (N-acetylcysteine)
- Dose:IV 150 mg/kg (1 h) → 50 mg/kg (4 h) → 100 mg/kg (16 h), total 300 mg/kg; or oral 140 + 70 ×17
