Scope and safeguards
What it covers, who it is for, and the hard rules that hold whatever the model says.
Scope
Identifies the product and retrieves cited guidance for trained clinicians. Does not diagnose, does not compute doses, does not replace the poison-centre call.
Chemical groups
Twelve groups covering the common Indian poisonings; 140 registry chemicals, each with its WHO 2019 class and source line; 649 WHO rows parsed. A brand that is not in the registry is looked up on the web and shown as unverified with the antidote section withheld.
Class without a chemical
If only the class is known, for example a bottle that says organophosphate but no chemical name is readable, Antidote withholds antidote guidance and shows the syndromic stop: treat the toxidrome you see and call the poison centre. When the clinician records cholinergic signs, Antidote gives the cited guidance for that toxidrome; it guided both such cases in the held-out set correctly. Without those signs, guidance stays withheld.
Labels in regional scripts
The registration number and the active-ingredient percentage are printed in Latin script on every label by law, so matching works; the printed antidote statement is shown as read and may be in Hindi or a regional language.
Guideline coverage
Cards quote the NHSRC module and the ISCCM 2024 statement. Where neither names the chemical group, the card falls back to the general approach and says so.
Citation integrity
Reported per card and on the Evals page; any quote the verifier cannot find on its page is replaced by a link to the page.
Hosted demo
Shared, rate-limited; records are a demo workspace. Hospital deployments run the API on their own machine with the open models.
What Antidote refuses
- Atropine or an oxime for any chemical group other than organophosphates and carbamates.
- Supplemental oxygen for paraquat before hypoxia, quoted from ISCCM 2024.
- Induced vomiting or ipecac for any pesticide ingestion.
- Any dose written by the model; doses appear only as quoted spans with their page.
- An antidote section when the product match is below 75 percent confidence.
- Any pesticide guidance for a product that is not a pesticide.
